Yes, we are in a potentially wet environment, but, we mostly pick up dry casualties and mostly can get them into the dry wheelhouse. To take an example, last year we had a fellow who thought he had indigestion on his yacht but called for help. We arrived and he was sat on deck flashing his torch and talking into his VHF to guide us to him. We came alongside, he walked on board, I escorted him into the wheelhouse, he turned grey, then green, then collapsed onto the deck. He was unconcious, not breathing and clearly no circulation. We started CPR but it took us 1/2 an hour to rv with an ambulance. They had a cardiac massage machine thingy and defib........all to no avail. I suspect that he would have died whatever we did, however, I would have liked to have been able to give him a better chance by trying a defib earlier. You are right, saltwater and electrics don't go well together but we can keep them apart..... Cheers John
