Here are my throughts on the mast head float. I don't think they are for all boats and sailing conditions. Spin boats seem to pitch pole more than turn over on there side (or at least I do)and I think the mast float would put a lot of stress on the mast when fliping. Sometimes you want to turtle the boat. In a Worrell leg a few years ago we were in a bad storm 50 to 60 mph winds with hail and turned the boat over while tacking to get closer to shore. We sat on the hull waiting for the worst to blow over and the boat just righted itself throwing us off and fliping over on its other side. We turtled the boat after that to keep from drifting so fast and waiting for the worst to blow over. I have turtled several different kinds of boats and don't think it is a big deal (unless you are in shallow water) to right the boat even with my wife and we have to add weight to the boat.
