I've made that flight many times in multi engine airplanes, but I wouldn't do it in a single.
Why?
Wouldnt do it in a single in any circumstances, or wouldnt do it without a raft?
Sincerely interested in your views have thought about it but not yet found time. Plenty of flying time in the past in Florida and the other end of the WI between islands - some in singles and some twin time.
