HURRICANE EARL

 SETTING OF PORT CONDITION X-RAY

 The National Hurricane Center has issued an Intermediate Advisory regarding Hurricane EARL.  Advisory #29, issued at 11 a.m. on September 1, 2010, reports that the eye of EARL was located approximately 350 miles east of the Bahamas.  EARL is moving toward the northwest at 17 mph but a gradual turn to the north is expected on Thursday.  On the forecasted track, the core of Hurricane EARL will pass well east and northeast of the Bahamas today and tonight and is expected to affect Cape Cod and the Islands within the next 48 hours.  EARL is a Category Three hurricane on the Saffir-Simpson Hurricane Wind Scale (sustained winds 111-130 mph).  Maximum sustained winds remain near 125 mph with higher gusts.  Some fluctuations in strength are likely during the next 24-36 hours.  EARL is a large hurricane with hurricane force winds extending outward to a 90-mile radius and tropical force winds extending out to 200 miles. 

Mariners in southeastern New England should closely monitor the progress of EARL over the next 48 hours. 
PORT CONDITION X-RAY: 

The Captain of the Port, Southeastern New England, has set Port Condition X-RAY in advance of Hurricane EARL.  While ports in southeastern New England remain open to all commercial traffic, the following preparatory measure is effective immediately: 

 ·         Owners, operators or agents of all self-propelled oceangoing vessels and barges over 500 gross tons (GT) and their supporting tugs must immediately advise the Captain of the Port of their intention to remain in port or to depart. 

o   Commercial vessels and barges greater than 500 GT desiring to remain in port must arrange safe mooring and shall complete and submit a Remaining Inport Checklist to the Captain of the Port by 1600 on 02 September 2010 for approval.  Checklists are available at homeport.uscg.mil/sene, or by calling Petty Officer Daniel Malec of Sector Southeastern New England at 401-435-2335.  Submit completed checklists to D01-SG-MsoProvInspections@uscg.mil, call 401-435-2335, or fax to 401-435-2399.  For more information contact the Sector Southeastern New England command center at 508-457-3211. 

o   Commercial vessels and barges over 500 GT intending to depart port must depart not later than 24 hours prior to the arrival of gale force winds.  Vessels bound for Narragansett, Mount Hope, Buzzards Bay, and Cape Cod Bay that are unable to depart 24 hours prior to the arrival of gale force winds are advised to seek an alternate destination.

·         Pleasure craft are advised to seek safe harbor.  Drawbridges may not be operating upon the onset of high winds or when evacuation is in progress.

 The Coast Guard will continue to monitor Hurricane EARL and, if necessary, may implement preventative measures to ensure the safety of mariners, vessels, and waterfront facilities.  Possible preventative measures include, but are not limited to, terminating lightering or transfer operations, rescinding permits for marine events, and directing vessel arrivals/departures to/from port.  We request that all port managers, harbormasters and marina managers please advise Mr. Kevin Blount when their facilities are at or approaching capacity for accommodating vessels seeking shelter from the approaching storm.  Mr. Blount can be reached at (401) 435-2321 or (401) 339-9776 (mobile), or by email at Kevin.J.Blount@uscg.mil.

 As always, any vessel casualties, pollution, or any incidents that may affect the navigable waterways of Rhode Island and Southeastern Massachusetts, including all of Cape Cod and the Islands, should be reported to Coast Guard Sector Southeastern New England command center via VHF channels 16 or 22, or via phone at 508-457-3211.

HURRICANE EARL

 SETTING OF PORT CONDITION WHISKEY

 The National Hurricane Center has issued an Intermediate Advisory regarding Hurricane EARL.  Advisory #25A, issued at 2 p.m. on August 31, 2010, reports that the eye of EARL was located northeast of the Dominican Republic.  EARL is moving toward the west-northwest at 14 mph but a gradual turn to the northwest is expected later today.  On the forecasted track, the core of Hurricane EARL will move over the open Atlantic, east of the Turks and Caicos Islands later today and tonight and is expected to affect the Cape Cod and Islands later this week.  Maximum sustained winds remain near 135 mph with higher gusts.  EARL is a Category Four hurricane on the Saffir-Simpson Hurricane Wind Scale (sustained winds 131-155 mph).  Some fluctuations in intensity are likely but EARL is forecast to retain Category Four status for the next day or two.

Mariners in southeastern New England should closely monitor the progress of EARL during the next 48 to 72 hours. 

PORT CONDITION WHISKEY: 

The Captain of the Port, Southeastern New England, has set Port Condition WHISKEY in advance of Hurricane EARL.  While ports in southeastern New England remain open to all commercial traffic, the following preparatory measure is effective immediately:

             At the January 2009 public meeting of the Dartmouth Waterways Management Commission, changes to Schedules A & B of the Dartmouth Mooring Regulations were unanimously and immediately enacted.   The heading to these mooring size regulation sections is now “Minimum Anchor and EXACT Ground Tackle Specifications.”                 The changes were enacted to address the widespread problem of many vessels sitting or riding on bottom chain heavier than could be moved by the attached vessel.  Heavy chain could be found laid out in any direction of the last strong gale, or sitting in a pile on the mooring anchor.  When all boats do not pull their full mooring scope according to the prevailing wind or wind/tide, the likelihood of boats bumping in our crowded harbor increases significantly.  In order to keep the same number and density of moorings accommodated, it was decided to require uniform mooring scope configurations based upon vessel size.               
           What impact does this have for each mooring permit holder?  Starting with every mooring which is due for inspection in 2009, the chain diameters for each mooring must change to match the required sizes for only the vessel of record approved by the Harbormaster for that mooring permit.  Inspections in each year hereafter will also require compliance at that inspection, as will any changes to your approved vessel of record.  If your bottom (or top) chain is oversized, it will need to be replaced with the appropriate diameter chain as specified in the Mooring Regulations.  Total mooring scope (length) remains unchanged and is based upon the mean high water site depth.  Mooring anchor weights described in the regulations remain minimum sizes and only this component of your mooring gear may be larger than recommended.         
          One additional change to mooring regulations affects only vessels less than 20’ in length moored north of the Bridge.  Moorings under “Schedule A” for approved vessels of record under 20’ in length should now have ½” diameter links for both top and bottom chains.               These changes are the result of deliberate public consideration by the Commission given to documented situations of property damage.  These mandatory changes are designed to promote public safety and the welfare of vessels moored in the tight boundaries of Padanaram Harbor.  Compliance is not optional and permits shall not be granted for non-conforming gear in Dartmouth waters.   These changes are not intended for mooring areas outside of Padanaram Harbor.  Mooring Service Providers are instructed to either bring indicated mooring gear into compliance with the new regulations, or to designate non-compliant gear as “failed” under Dartmouth Mooring Regulation 15(ii).

Rusty-Colored Algae Floats Again in Buzzards Bay This summer marked the fifth summer since 2005 that Baywatcher volunteers reported cloudy streaks of rust-colored water in Buzzards Bay – the sign of abnormal amounts of Cochlodinium polykrikoides, a dinoflagellate, which is a type of phytoplankton or single-celled algae. Dinoflagellates, such as Cochlodinium, naturally occur in Buzzards Bay and are likely present all the time, but usually occur in significantly less densities. Whenever there is a population explosion, or “bloom,” of these microalgae, cell densities may exceed millions of cells per liter of water. Characteristic of all dinoflagellates, Cochlodinium cells have two flagella, or thin, whip-like outgrowths used for swimming, and armored plates of tissue. However, Cochlodinium cells also contain reddish pigments that give the water a rust-colored hue when high densities of this organism accumulate at the surface. Although a Cochlodinium bloom looks rusty-red, it is not the type of algae that is injurious to humans, such as the red tide alga, Alexandrium, which contains a toxin that attacks the nervous system in marine animals and humans. Cochlodinium does not contain any toxins; however, if a Cocholodinium bloom becomes large enough, especially in a semi-enclosed system such as a bay or harbor, it can kill fish, as the overabundance of algae consume all of the oxygen in the water. Large concentrations of Cochlodinium may also affect the growth, survival and development of some shellfish, such as oysters, but much remains unknown about these effects, and thus, is the focus of ongoing research. Algae blooms tend to occur when environmental conditions such as temperatures, nutrients, and turbulence change, triggering the rapid growth of algal cells. For example, when a long dry spell is followed by heavy rains, nutrients such as nitrogen and phosphorus contained in farm fertilizers, animal wastes and sewage-treatment-plant discharges are flushed into the bay. This addition of excess nutrients to the bay fuels the production of algal blooms similar to how fertilizer promotes the growth of your lawn or garden. “These blooms appear to be increasing in frequency, which is an indication that significant changes are occurring in Buzzards Bay,” said Coalition Director of Monitoring Programs Tony Williams. According to Dave Whittaker, Senior Marine Fisheries Biologist at the Massachusetts Division of Marine Fisheries, this “rusty tide” has occurred in Buzzards Bay long before 2005, but blooms were more sporadic. “In the last three or four years, blooms have been much more regular and pronounced with a much greater spatial distribution,” Whittaker explained. “We actually had a bloom as late as three weeks ago in Clarks Cove in New Bedford following that last extremely heavy rain event. With the size of these blooms, thank goodness Cochlodinium is not harmful to humans.” This year Baywatchers first began reporting observations of rusty-colored water at the end of July in Fiddlers Cove, which was about three weeks earlier than last year’s initial report. Baywatchers then reported seeing blooms two weeks later in August in Wings Cove, the Wareham River, West Falmouth Harbor, and Snug Harbor. Tracking trends, such as recording the occurrence of these “rusty tide” events, is critical to understanding the changing health of the bay and how human activities impact the bay ecosystem. As the Coalition’s 2007 State of the Bay Report reveals, the overall health of the bay is declining and algae blooms are just one sign of troubled waters. The Coalition will continue to monitor the bay’s health and collect long-term data to provide the information necessary to make informed, science-based decisions about the restoration and protection of Buzzards Bay. The Coalition needs your help in monitoring the health of Buzzards Bay. If you observe an algae bloom in Buzzards Bay, immediately contact Tony Williams, Coalition Director of Monitoring Programs at 508-999-6363 ext. 203 or e-mail at williams@savebuzzardsbay.org, with the location and a description of the bloom.

HURRICANE AND STORM PREPARATION

Hurricane and Storm Preparation

Dartmouth has been spared the direct hit of a major (category 4 or 5) hurricane for the life of most median-aged residents.   The early season Hurricane Bob in August of 1991 devastated Padanaram Harbor with a direct hit, but fortuitously struck at a low tide.  The impact upon the relatively sheltered harbor was significant and decimated the vessels left at anchor or on moorings.  The Padanaram Bridge and causeway were inoperable and impassible for up to one week following the storm.  Broken boats, some with moorings still attached, were strewn across the causeway.  In excess of one hundred vessels of all types and sizes foundered along the town shoreline, roadways, and causeway.  To this day, some vessels lost during Hurricane Bob still remain unaccounted for.  Low-lying areas, including roadways, parking lots and businesses were flooded with a storm surge that was minimal in comparison to similar storms.    Most private and business docks were either destroyed severely impacted by waves, loose boats, and flotsam.  High Hurricane season usually lasts from late August through October.   Hurricane preparation is not a joke.

The Saffir-Simpson scale classifies hurricanes into five categories according to their intensity, allowing comparisons of past hurricanes and communication of the strength of an approaching storm to the public.

Category 1: Minimal Damage Winds of 74-95 mph and storm surges of 4-5 ft. No significant wind damage to well constructed buildings. Some damage is done to poorly constructed signs. Wind damage primarily occurs to mobile homes, shrubbery, trees, and foliage. Low lying roads are inundated by storm surge. Minor pier damage occurs. Example: Danny, 1997 & Bob, 1991.

Category 2: Moderate Damage Winds of 96-110 mph and storm surges of 6-8 ft. Some roofing material, doors, windows of homes and businesses are damaged by winds. Considerable wind damage done to mobile homes and vegetation. Low lying roads are inundated by storm surge. Considerable damage done by storm surge and wave action to piers. Small craft in unprotected anchorages break their moorings. Example: Flossy, 1956

Category 3: Extensive Damage Winds of 111-130 mph and storm surges of 9-12 ft. Winds cause structural damage to homes and utility buildings with a minor amount of curtainwall failure. Mobile homes are destroyed. Storm surge flooding destroys many smaller buildings while large buildings are damaged by floating debris. Terrain continuously lower than 10 feet above mean sea level is flooded. Example: Andrew, 1992

Category 4: Extreme Damage Winds of 131-155 mph and storm surges of 13-18 ft. More extensive curtainwall failures with some complete roof failure on homes. Major damage to lower floors of homes and businesses from storm surge flooding. Terrain continuously lower than 15 feet above mean sea level is flooded. Example: Audrey, 1957

Category 5: Catastrophic Damage Winds greater than 155 mph and storm surges greater than 18 ft. Compete roof failure of many homes and businesses. Complete structural failure of many small buildings. Major storm surge flooding to areas lower than 20 feet above mean sea level. Example: Camille, 1969 Source: National Oceanic and Atmospheric Administration

High tide during a hurricane in Dartmouth can rise 4-6+ feet above the normal high tide caused by lowered atmospheric pressure. Wind-caused surge can form an addition and unpredicted wedge of water on top of this tide. Boats moored in high-energy areas such as the outer harbor will lose the protection of the breakwater which will be deeply submerged at high tide. These boats must be moved to safer harbor before the storm hits. Mooring scope at this time may become too short and cause anchors to pull.

Boat ramps will be jammed at the time close to the storm. Therefore, if you have reached the end of your useful boating season, consider an early haul out.

THINGS YOU SHOULD DO- SHORT OF HAULING OUT

MOORED BOATS:

1. Inspect your mooring tackle and renew all parts that show signs of serious wear. This should include quality of chain, splices, and condition of thimbles and shackles.   Especially important is the quality and sufficiency of chafing gear. (See  #3 below).

2. All moorings during these months should be equipped with secondary storm painter (mooring line) to attach to the opposite bow cleat.

3. Equip all mooring lines passing through bow chocks with chafing equipment which can include a short piece of rubber hose or vinyl tubing protecting the lines from wearing through. Wear and tear of mooring pennants at deck level has been the most common reason in Dartmouth for mooring failure.

4. Inspect the security of bow cleats and eyes. Sailing vessels extend mooring lines back to the base of the mast, remove and stow all sails.   The less windage you present to the storm, the less impact the storm-force winds will have upon your vessel, its mooring, and related deck hardware.

5. Batteries driving automatic bilge pumps should be fully charged and float switches tested for good working order. Bilges should be cleaned of oil and contaminants.

6. All through hull fittings equipped with valves as heads, holding tank valves, and exhaust overflows should be placed in closed position.

7. Where practical add to the mooring scope by lengthening the painter. Be sure you maintain clearance with boats around you. Position all extra fenders to fend off blows.

8.  Do not attempt to “ride-out” a storm on your vessel.  It may sound valiant and adventurous, but I have not yet heard of a single positive memory generated from such foolhardiness.  Resulting deaths have been documented.  The nature of the chaos found in a harbor during a hurricane prohibits even the saltiest mariner from being able to make any effective corrective maneuvers while dodging loose boats and flotsam.

DOCKSIDE BOATS

1. Secure extra fender between boats and docks. Make use of a fender board where vessel is tied up between pilings.

2. Double up all dock lines. Be sure spring lines are secured in both directions and make certain cleats are well secured.

3. In areas of floating docks, tie only to near top of the pilings, otherwise the rising tide will "jack" the pile or otherwise pull the boat under.

4. Owners with vessels tied alongside a fixed pier should make certain that the gunwales will not get caught under the dock as the tide rises. The boat may be warped away from the pier using an anchor as an outhaul.

5. Disconnect all shore power lines going to the vessel before the storm hits.

6. Attempt to dock sailboats so that masts will not be "caught" on one another when boats rock.

7. Wherever possible, get off of a dock or float unless in a very protected harbor.

BOATS HAULED OUT

1. All day sailors and light-weight boats which can make use of trailers should be taken out of the water as soon as possible.

2. Sailboats dinghy type should be flooded with freshwater on their trailers or tied to stakes as a means to hold them down.

3. At home, park boats close to buildings, if possible, to shelter it from the effects of direct wind gusts..

4. Boats stored using jack stands on soft ground, mud, sand, or gravel should use plywood under each stand as a precaution to prevent each stand from settlement. Make certain each jack is snug firmly against the boat hull and use safety chains to "cross-lock" jacks.

The USCG has installed a new light at the end of the Breakwater.  The temporary red lighted buoy has been removed.

Notice to Mariners:  The Padanaram Breakwater Light (LL 16765) at the end of the breakwater at the entrance to Padanaram Harbor was knocked out in a recent storm.  The Coast Guard Aid to Navigation Team has been notified. Please use caution when approaching the entrance to the harbor.

The Dartmouth Waterways Management Commission is responsible for regulating the safe allocation of the greatest number of accommodations within the public waterway. Padanaram North Harbor will be re-gridded with all mooring sites re-aligned on the basis of the size and characteristics of each registered vessel of record.  The need for the planned re-grid lies in the current irregular distribution of sites, inconsistent swing circles, draft constrictions and high public demand for moorings.     The re-grid project is designed to safely accommodate the greatest number of vessels within clearly-defined mooring circles, define safe thoroughfares or navigational passages through the mooring field and from the public launch area, and remove any improperly-marked obstructions found.   Due to circumstances beyond our control, the timing of this project has been delayed until October 2010.   At this time, all mooring locations north of the Padanaram Bridge will be adjusted.
The Waterways Commission is developing a precise and thorough plan for the details of this re-grid project.  Mooring Inspections that are due prior to this project must be completed to be eligible for a continued permit in the new grid.  All moorings will require proper markings, and all vessels must be removed from north side mooring sites prior to October 18, 2010.  Please continue watching the Waterways website (www.dartmouthharbormaster.com) for developing details on this immense undertaking.  Thank you for your cooperation, we will post updated information as it becomes available.

The Dartmouth D.P.W. will maintain the posted opening schedule for the Padanaram Bridge through 2100 hrs (9 p.m.) on October 31, 2009.   Mariners who cannot clear the span by lowering antenna or other readily lowered structures may request a bridge opening between 0500 (5a.m.) and 2100 (9p.m.) any day on the hour.  Between 0500 (5a.m.) and 0800 (8 a.m.), and at 2030 (8:30 p.m.) an opening may be requested on those half-hour marks only.  Hail the Padanaram Bridgetender on VHF radio Channel 13  prior to the requested opening time, prior to October 31st.

Bridge openings after October 31st must be made 24 hours in advance by telephone request to the DPW (during DPW business hours only) at 508-999-0740.  Please note that the Padanaram Swing Bridge is operated by the Dartmouth Department of Public Works, and not the Harbormaster Office.

For example, when a long dry spell is followed by heavy rains, nutrients such as nitrogen and phosphorus contained in farm fertilizers, animal wastes and sewage-treatment-plant discharges are flushed into the bay. This addition of excess nutrients to the bay fuels the production of algal blooms similar to how fertilizer promotes the growth of your lawn or garden. “These blooms appear to be increasing in frequency, which is an indication that significant changes are occurring in Buzzards Bay,” said Coalition Director of Monitoring Programs Tony Williams. According to Dave Whittaker, Senior Marine Fisheries Biologist at the Massachusetts Division of Marine Fisheries, this “rusty tide” has occurred in Buzzards Bay long before 2005, but blooms were more sporadic. “In the last three or four years, blooms have been much more regular and pronounced with a much greater spatial distribution,” Whittaker explained. “We actually had a bloom as late as three weeks ago in Clarks Cove in New Bedford following that last extremely heavy rain event. With the size of these blooms, thank goodness Cochlodinium is not harmful to humans.” This year Baywatchers first began reporting observations of rusty-colored water at the end of July in Fiddlers Cove, which was about three weeks earlier than last year’s initial report. Baywatchers then reported seeing blooms two weeks later in August in Wings Cove, the Wareham River, West Falmouth Harbor, and Snug Harbor. Tracking trends, such as recording the occurrence of these “rusty tide” events, is critical to understanding the changing health of the bay and how human activities impact the bay ecosystem. As the Coalition’s 2007 State of the Bay Report reveals, the overall health of the bay is declining and algae blooms are just one sign of troubled waters. The Coalition will continue to monitor the bay’s health and collect long-term data to provide the information necessary to make informed, science-based decisions about the restoration and protection of Buzzards Bay. The Coalition needs your help in monitoring the health of Buzzards Bay. If you observe an algae bloom in Buzzards Bay, immediately contact Tony Williams, Coalition Director of Monitoring Programs at 508-999-6363 ext. 203 or e-mail at williams@savebuzzardsbay.org, with the location and a description of the bloom.

HURRICANE AND STORM PREPARATION

Hurricane and Storm Preparation

Dartmouth has been spared the direct hit of a major (category 4 or 5) hurricane for the life of most median-aged residents.   The early season Hurricane Bob in August of 1991 devastated Padanaram Harbor with a direct hit, but fortuitously struck at a low tide.  The impact upon the relatively sheltered harbor was significant and decimated the vessels left at anchor or on moorings.  The Padanaram Bridge and causeway were inoperable and impassible for up to one week following the storm.  Broken boats, some with moorings still attached, were strewn across the causeway.  In excess of one hundred vessels of all types and sizes foundered along the town shoreline, roadways, and causeway.  To this day, some vessels lost during Hurricane Bob still remain unaccounted for.  Low-lying areas, including roadways, parking lots and businesses were flooded with a storm surge that was minimal in comparison to similar storms.    Most private and business docks were either destroyed severely impacted by waves, loose boats, and flotsam.  High Hurricane season usually lasts from late August through October.   Hurricane preparation is not a joke.

The Saffir-Simpson scale classifies hurricanes into five categories according to their intensity, allowing comparisons of past hurricanes and communication of the strength of an approaching storm to the public.

Category 1: Minimal Damage Winds of 74-95 mph and storm surges of 4-5 ft. No significant wind damage to well constructed buildings. Some damage is done to poorly constructed signs. Wind damage primarily occurs to mobile homes, shrubbery, trees, and foliage. Low lying roads are inundated by storm surge. Minor pier damage occurs. Example: Danny, 1997 & Bob, 1991.

Category 2: Moderate Damage Winds of 96-110 mph and storm surges of 6-8 ft. Some roofing material, doors, windows of homes and businesses are damaged by winds. Considerable wind damage done to mobile homes and vegetation. Low lying roads are inundated by storm surge. Considerable damage done by storm surge and wave action to piers. Small craft in unprotected anchorages break their moorings. Example: Flossy, 1956

Category 3: Extensive Damage Winds of 111-130 mph and storm surges of 9-12 ft. Winds cause structural damage to homes and utility buildings with a minor amount of curtainwall failure. Mobile homes are destroyed. Storm surge flooding destroys many smaller buildings while large buildings are damaged by floating debris. Terrain continuously lower than 10 feet above mean sea level is flooded. Example: Andrew, 1992

Category 4: Extreme Damage Winds of 131-155 mph and storm surges of 13-18 ft. More extensive curtainwall failures with some complete roof failure on homes. Major damage to lower floors of homes and businesses from storm surge flooding. Terrain continuously lower than 15 feet above mean sea level is flooded. Example: Audrey, 1957

Category 5: Catastrophic Damage Winds greater than 155 mph and storm surges greater than 18 ft. Compete roof failure of many homes and businesses. Complete structural failure of many small buildings. Major storm surge flooding to areas lower than 20 feet above mean sea level. Example: Camille, 1969 Source: National Oceanic and Atmospheric Administration

High tide during a hurricane in Dartmouth can rise 4-6+ feet above the normal high tide caused by lowered atmospheric pressure. Wind-caused surge can form an addition and unpredicted wedge of water on top of this tide. Boats moored in high-energy areas such as the outer harbor will lose the protection of the breakwater which will be deeply submerged at high tide. These boats must be moved to safer harbor before the storm hits. Mooring scope at this time may become too short and cause anchors to pull.

Boat ramps will be jammed at the time close to the storm. Therefore, if you have reached the end of your useful boating season, consider an early haul out.

THINGS YOU SHOULD DO- SHORT OF HAULING OUT

MOORED BOATS:

1. Inspect your mooring tackle and renew all parts that show signs of serious wear. This should include quality of chain, splices, and condition of thimbles and shackles.   Especially important is the quality and sufficiency of chafing gear. (See  #3 below).

2. All moorings during these months should be equipped with secondary storm painter (mooring line) to attach to the opposite bow cleat.

3. Equip all mooring lines passing through bow chocks with chafing equipment which can include a short piece of rubber hose or vinyl tubing protecting the lines from wearing through. Wear and tear of mooring pennants at deck level has been the most common reason in Dartmouth for mooring failure.

4. Inspect the security of bow cleats and eyes. Sailing vessels extend mooring lines back to the base of the mast, remove and stow all sails.   The less windage you present to the storm, the less impact the storm-force winds will have upon your vessel, its mooring, and related deck hardware.

5. Batteries driving automatic bilge pumps should be fully charged and float switches tested for good working order. Bilges should be cleaned of oil and contaminants.

6. All through hull fittings equipped with valves as heads, holding tank valves, and exhaust overflows should be placed in closed position.

7. Where practical add to the mooring scope by lengthening the painter. Be sure you maintain clearance with boats around you. Position all extra fenders to fend off blows.

8.  Do not attempt to “ride-out” a storm on your vessel.  It may sound valiant and adventurous, but I have not yet heard of a single positive memory generated from such foolhardiness.  Resulting deaths have been documented.  The nature of the chaos found in a harbor during a hurricane prohibits even the saltiest mariner from being able to make any effective corrective maneuvers while dodging loose boats and flotsam.

DOCKSIDE BOATS

1. Secure extra fender between boats and docks. Make use of a fender board where vessel is tied up between pilings.

2. Double up all dock lines. Be sure spring lines are secured in both directions and make certain cleats are well secured.

3. In areas of floating docks, tie only to near top of the pilings, otherwise the rising tide will "jack" the pile or otherwise pull the boat under.

4. Owners with vessels tied alongside a fixed pier should make certain that the gunwales will not get caught under the dock as the tide rises. The boat may be warped away from the pier using an anchor as an outhaul.

5. Disconnect all shore power lines going to the vessel before the storm hits.

6. Attempt to dock sailboats so that masts will not be "caught" on one another when boats rock.

7. Wherever possible, get off of a dock or float unless in a very protected harbor.

BOATS HAULED OUT

1. All day sailors and light-weight boats which can make use of trailers should be taken out of the water as soon as possible.

2. Sailboats dinghy type should be flooded with freshwater on their trailers or tied to stakes as a means to hold them down.

3. At home, park boats close to buildings, if possible, to shelter it from the effects of direct wind gusts..

4. Boats stored using jack stands on soft ground, mud, sand, or gravel should use plywood under each stand as a precaution to prevent each stand from settlement. Make certain each jack is snug firmly against the boat hull and use safety chains to "cross-lock" jacks.

Rusty-Colored Algae Floats Again in Buzzards Bay This summer marked the fifth summer since 2005 that Baywatcher volunteers reported cloudy streaks of rust-colored water in Buzzards Bay – the sign of abnormal amounts of Cochlodinium polykrikoides, a dinoflagellate, which is a type of phytoplankton or single-celled algae. Dinoflagellates, such as Cochlodinium, naturally occur in Buzzards Bay and are likely present all the time, but usually occur in significantly less densities. Whenever there is a population explosion, or “bloom,” of these microalgae, cell densities may exceed millions of cells per liter of water. Characteristic of all dinoflagellates, Cochlodinium cells have two flagella, or thin, whip-like outgrowths used for swimming, and armored plates of tissue. However, Cochlodinium cells also contain reddish pigments that give the water a rust-colored hue when high densities of this organism accumulate at the surface. Although a Cochlodinium bloom looks rusty-red, it is not the type of algae that is injurious to humans, such as the red tide alga, Alexandrium, which contains a toxin that attacks the nervous system in marine animals and humans. Cochlodinium does not contain any toxins; however, if a Cocholodinium bloom becomes large enough, especially in a semi-enclosed system such as a bay or harbor, it can kill fish, as the overabundance of algae consume all of the oxygen in the water. Large concentrations of Cochlodinium may also affect the growth, survival and development of some shellfish, such as oysters, but much remains unknown about these effects, and thus, is the focus of ongoing research. Algae blooms tend to occur when environmental conditions such as temperatures, nutrients, and turbulence change, triggering the rapid growth of algal cells.
