If hypothermia leaves you cold, then read this....
If you're like me, and I know I am, I shudder at the thought of freezing to death.
Bad pun aside, the human body operates best when its internal temperature ranges between 98 and 100-degrees F. The body starts to lose function when its internal temperature falls below 96-degrees F. Hypothermia is a bitch.
News of the blizzard expected to hit the northeast U.S. this afternoon brought hypothermia warnings to the fore. Hypothermia is easily avoided for most. Avoid the cold. Dress warmly in layers. Pay your heating bill. Be alert for signs of hypothermia.
Wikipedia -- you can always trust Wikipedia -- lists mild, moderate and severe hypothermia symptoms. At its mildest, hypothermia can cause involuntary shivers and mental confusion. At worst, hypothermia causes loss of muscle coordination, decreases in heart and breathing rate, blood pressure and can cause hypoglycemia.
The Power Squadrons is a boating civic & safety group. We are concerned with captains and crew who fall from the boat into cold water. This 2007 story at The Ensign is a dandy piece on hypothermia safety for boaters. It includes a chart that show survival times based on water temperature. If you fall into 32.5-degree water, you've got 15 to 45 minutes to get the heck out.
A second chart lists survival rates in 50-degree water with and without flotation devices. A life vest keeps you warmer as well as afloat. That's why the Coast Guard has become a doggone pest about wearing one all the time.
By the way, boaters, alcohol won't keep you warm in cold water. Instead, it speeds up hypothermia's effect. Save the drinkin' for the dock party.
Hypothermia is best avoided. If you must run the risk on land or on the water, be ready.

"Since the attacks of Sept. 11, 2001, improving the safety of major waterways and large ports has been a priority of the Department of Homeland Security. And the bay leads directly into the Port of Baltimore.
"The new $2 million, 41-foot boat will improve the Coast Guard’s performance and ability to respond to incidents. The new boat has significantly faster speeds—maximum of 42.5 knots—and a longer range at about 250 nautical miles, according to a release."

Warning From Topper Shutt: Ocean Temp Is Cooler Than On Thanksgiving
Some of the best boating news over the Memorial Day weekend (Thank you, veterans) has been penned by DC area weathermen dutifully repeating warnings issued by the National Weather Service. WUSA-TV 9 meteorologist Topper Shutt is the latest contributor with his piece in the Sunday, May 29, 2011 edition of The Washington Examiner.
Shutt's "Chilly water" message warning of hypothermia appears in the Weather News You Can Use column. Sadly, WashingtonExaminer.com did not post an active link to the story, so as a public service, I'm posting the entire piece here. This will assure two or three more people, mostly relatives, get this information.
Remember, full credit goes to Channel-9 weatherman Topper Shutt.
"Many people flock to the shore for Memorial Day weekend. If I suggested you go to the beach on Thanksgiving, you would think I was crazy. However, the ocean is actually warmer on Thanksgiving Day than on Memorial Day.
"The water temperature on Thanksgiving Day is typically 64 degrees. On Memorial Day, it's only about 61 degrees.
"The ocean is still recovering from winter and hasn't received the added boost from the Gulf Stream. The atmosphere is vertically mixed, but the ocean is horizontally mixed.
"If you get into the water this weekend, don't stay in long. It is possible to get hypothermia in water that is about 50 to 60 degrees. Hypothermia can set in between one and two hours.
"Although the sun might not feel that hot, late May sun is equivalent to July sun, so remember to apply sunscreen."

Be Careful On The Potomac

ANNAPOLIS, Md. — Maryland Natural Resources Police say they plan to patrol aggressively on waterways across the state this holiday weekend.
Natural Resources Police say officers will target boaters driving in a reckless or negligent manner or under the influence of alcohol. And they will also be making sure boaters have required safety equipment.
Authorities also are advising boaters to keep a cautious eye on the upper Potomac River, where recent rains had pushed the river to hazardous levels. NRP says an advisory for the upper Potomac has expired, but any significant additional rainfall could cause hazardous conditions again.
NRP says last year its officers responded to more than 323 boating accidents that led to 13 deaths.
~ Associated Press Story taken from here.
Montgomery County Fire and EMS crews will be handing out hundreds of these fliers in Great Falls Park reminding people that you cannot swim, wade, or drink alcohol there.
Because as enticing as the Potomac is this time of year, it is always dangerous. Crews pulled a 12 year old boy who was swimming near White's Ferry after he became fatigued and couldn't make it on his own.
Mark Gleason, who patrols the C & O Canal on bicycle for the US Park Service, says the Potomac is very deceptive.
In some places, the power of the Potomac is obvious. But in others--a deadly hazard lurks beneath the tranquil surface.
"Most of the accidents people here are when they step in and the water is much faster underneath and it sweeps them away."

Don't Go Into The Water

Flooding Potomac presents hazards for area boaters according to an online story by WTOP.
Heavy rains in the area has the Potomac River cresting its banks and creating navigational hazards for all boaters. The D.C. Harbor Police advises all boaters to stay off the Potomac through the weekend (20-22 May 2011).
A similar story on www.nbcwashington.com says the worst of the flooding is probably over, but advises boaters to stay off the Potomac this weekend. That story gave high tide (11:15 AM and 11:56 PM at Key Bridge) on Friday, 20 May, as a time for special caution for boaters and anyone along the waterfront.
The National Weather Service issued a Flood Warning for the Potomac River at Point Of Rocks affecting Frederick (MD) and Loudoun (VA) Counties and at Little Falls affecting Montgomery (MD) and Fairfax (VA) Counties. The warning is in effect until this evening. The warning was issued at 4:24 PM today.
A warning means that flooding is actually occurring. Take extreme caution when driving through flood areas. A vehicle can be swept away in as little as two feet of flowing water. Cars are not boats!
If you have first-hand knowledge of conditions along our waterways, leave a comment.

Did you hear the one about the fish just jumped into the boat?
Just like those old fish stories, these carp just jumped into the boat. Carp do that when startled. You would think they'd be used to motor boats on a well travelled river like the Wabash.
Oh yeah. There's a safety message here. Note that these boaters are wearing life vests. Good idea on a small boat. Especially when a 20-pound flying fish can knock you out.
See the Coast Guard's web page on life vest selection, care and use here.

Wave Running
Riding out the waves can be a fun part of boating...if you know what you are doing.
This skipper took the first wave bow-on. That's good, but he did not, or could not, maintain his position, so the second wave hit him abeam. That's not good. The skipper rights the boat to face the bow to the third wave. That's good, but it's a bigger wave. like Gilligan, the tiny ship--and the passenger--was tossed.
Even on recreational boats, if the helmsman is also the owner and, therefore, captain, he is responsible for passenger safety and for every action of the crew. If I were captain of this vessel, I would not maintain station in a boat that small with oncoming waves that big. And everyone on board, including me, would be wearing life vests.

I Must Go Down To The Sea, But Not With The Ship

You have to weather the storm
Boat long enough and you'll eventually run aground, they say. Cruise the Chesapeake long enough and you'll get caught in a squall.
Today's Washington Post tells the story of Steve Murfin who was caught in a violent storm last August. Murfin was tooling around the Eastern Bay just off St. Michael's (If you don't know where that is, you're just not a Bay boater) in his 17-foot Boston Whaler.
Murfin had been tracking the approach of a storm. He decided to head to home port about 90 minutes before the weather was predicted to hit. Then, two bad things happened. First he couldn't start his engine. Second, the squall hit at just that moment. Like Gilligan, Murfin's tiny ship was tossed.
A Good Samaritan on board the vessel Her Baby arrived and gave Murfin a tow through the worst of the storm. The Post's description of that adventure is as stirring as any you'll find in classic sea yarns.
Her Baby towed Murfin safely to his dock on the Wye River. She departed without Murfin so much as knowing her captain's name. Just another example of good boaters being good boaters.
Captains are expected to help other boaters in distress, if it is within their capability to do so and when such help does not constitute a danger to themselves. This is especially true in the case of accident.
The Boat Handling S102 manual (2002) of the Power Squadron's Seamanship Course has these legal tips for captains offering Good Samaritan tows:
- The skipper (of the towing boat) must have the proper equipment and be mentally prepared.
- Insurance coverage may change if you tow someone. Don't wait until you are faced with a towing situation to look into this. Check your insurance policy now--and every time it is renewed.
- Before towing, make sure actions are appropriate, reasonable and properly documented because they are subject to review in the event of mishap, damage, or injury. Keep a detailed log of every action taken.
- Under no circumstances should the owner of the boat doing the towing accept anything of value from the owner or crew of the boat to be towed. Such acceptance is regarded as being engaged in the business of commercial towing.
- The towing boat skipper should make clear that it is his /her intention to help a fellow boater. The owner of the towed boat must make clear that the assistance provided does not constitute a salvage operation. Crews should remain on their respective boats. If the crew from the towing boat boards the boat to be towed, there is possibly the implication that the skipper of the boat to be towed has surrendered command. The towing skipper should use lines from the boat to be towed.
Postscript: When the words "federal" and "boating" appear in the same sentence, it applies to navigable waters. To me, that means water under the control of the U.S. Army Corps of Engineers and patrolled by the U.S. Coast Guard. States have Good Samaritan laws, but each have their own local twist. Federal or State, Good Samaritans are not expected to, and should not, attempt something beyond their ability. Standing by until the authorities arrive is also a Good Samaritan act.
