After reading all the stuff on mast floats (via Google), my conclusion on turtles... is that all masts should have an eye strap or straps or some optional attachment point near the tip where a buoyancy bag or some flotation device can be fitted.

I am surprised that this attachment point is not a standard safety feature item. (It is with some, yes. Like the Wave that has to have one no matter what.)

With marginal swimmers on or when in locations where the water is shallower, then the float looks like a necessity. (Marginal swimmers also make it a necessity not to go out where turtling may be required unless there is a safety boat around.)

The Weta certainly does have a very slick righting concept...

A while back, Jeremy ran a "what-if" here on an TheMightyHobie18 that had to be turtled because of someone going overboard. It was a nice mental exercise (not for them, for the forum). Turtling was about the only option in that case. What those guys could have done better, IMO, was pre-think their boat to conditions before going out...

Anyway, it all seems to be personal preferences and I don't want to beat a turtle... that is already, like, dead.
