Terry:

Thanks for the advice, but I ordered the Hobie Bob yesterday before I saw your note about the slip over foam. Some years ago, I tried using heavy velcro strips to attach pieces of closed cell foam to the top of the mast and it worked. Problem was that when I got the mast back up into the air, the water seperated the foam from the mast by getting under the glue on the foam.

Matt:

The reason the Hobie 18 turtles a lot easier than the Prindle or the Tiger is probably the Comp tip; it seems like a dead extension to the mast and seems to help drive the mast under water. The Hobie Bob will work...
