As the cooler temperatures make their way south to the Houston area we find increased risks with boating...Should you fall over board and remain in the water very long you are at increased risk for
hypothermia.
Hypothermia is actually defined as any time the core body temperature falls below 95* F. Taking extra precautions in cooler temperatures is the key to avoiding a tragic outcome. On Friday December 2, 2010 we had a shrimp boat capsize in our waters and 3 of the 4 men were rescued clinging to debris, sadly they have to be treated for hypothermia which leaves a grim reality that the 4th person in the water probably has hypothermia as well leaving them at greater risk of drowning. He has still not been located and the Coast Guard suspended it's search for him.

Make sure there is a working
PFD for each person aboard and make sure they are wearing it. By having the life vest on you give yourself an advantage should you fall over board. Once you fall into the cold water if you begin to lose dexterity and function you will not be able to swim to keep your head above water a
PFD is designed to help you stay afloat. Wearing it is the only way to be sure it will work.
With that being said there are some things that can make your journeys on the water safer and help protect you against
hypothermia. The first thing you need is a life raft this will help get you our of the water if your boat were to capsize or sink. even if you go into the water and become wet and cold you can increase your chances by having a way to get out of the water. Pack some extra isothermal blankets in your ditch bag and use them to attempt to stay warm once you are in the life raft. Purchase an
EPIRB or
PLB or both and keep the
PLB with you. The sooner they can find you the better chance you have of recovering fully from
hypothermia.
If you plan on making overnight trips in cold weather you may want to consider an immersion suit for each crew member. The immersion suits are designed to help you stay warm, they will make a big difference in how quickly your body begins to go through the stages of
hypothermia.
As always file a float plan, check dates on safety gear, check all components of the boat, and be prepared for the worst conditions and you will always have a more enjoyable boating experience.
There are a lot of ditch bag items that can help one survive and if you need help choosing these items we will be happy to sit down and help you. We can also provide you with more information on PFDs, PLBs, EPIRBs, and Life Rafts.

Water Temperature | Loss of Dexterity | Exhaustion or | Expected Time of |
Degrees C | Degrees F | with no protective clothing | Unconsciousness | Survival |
0.3 | 32.5 | Under 2 min. | Under 15 min. | Under 15 to 45 min. |
0.3 to 4.5 | 32.5 - 40 | Under 3 min. | 15 to 30 min. | 30 to 90 min. |

15.5 to 21 | 60 - 70 | 30 to 40 min. | 2 to 7 hrs. | 2 to 40 hrs. |
21 to 26.5 | 70 - 80 | 1 to 2 hrs. | 2 to 12 hrs. | 3 hrs. to indefinite |
Over 26.5 | Over 80 | 2 to 12 hrs. | Indefinite | Indefinite |
The above table is simply a reference, remember each person's body reacts differently and one may become colder more quickly if they suffer from certain illnesses or if they take blood thinning medications.
