SEALS are highly trained and motivated, true. They have the same metabolism as you and me. During the recent raft tests, I talked at length with the USCG senior rescue swimmer Butch. We both served at AIRSTATION KODIAK. It would seem the SEALS train on Kodiak, and the Coast Guard recieved several evac requests for hypothermia. So what does this mean? Should we all buy Coast Guard issue knives? Once again the NSW kayak club's article is relevent. " Buy the best gear available, and then never make a decision based on having that gear."
