Guys, thanks for the info. My aim is to be able to car top, mainly because I have to take a ferry to get on and off the Island, so trailer or overhangs = more dollars.

In theory, could such a mast be made two piece? My ideal would be a slightly shorter version of the Weta mast.

Has anyone put any thought into an unstayed mast? I would have thought previously that it wouldn't be stiff enough for the righting moment of a cat - or to trap off. But the Devoti One is carrying 11m2 and a 15m2 kite with no stays and designed for heavyweight crews, so it could be a possibility. It would be great just to able to drop the mast in and go.
