I think Tiki said he's never been able to do a full flip. He only gets 1/4 of the way there. Must not be able to get enough air to get the mast all the way under. A lot like first attempted flips on a knee board or wake board... not enough air... end up dragging the "mast" in the water. <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />
