Sugar-free boat, hehe. Reminds me of an experiment by some French dude, he wrote a book about it, Naufragé Volontaire. Don't remember which ocean but he crossed it in an inflatable dinghy, one of those emergency boats on big ships. He wanted to show it was quite possible to do this, because it was a big deal at the time. No supplies to begin with except the basic tools included in those emergency dinghys, he had to get water and food from the sea. Sugar-free boat for sure.
