Somewhat related to this topic:

I spoke to someone last summer who wanted to take the middle hull of a windrider 17 tri (non foiling version) and make a mold for a fiberglass hull out of it. Modify it by putting on a centerboard, then taking beachcat hulls and putting lifting foils on them like an Orma 60' and stick an inter20 rig on it.

Sounded crazy but I bet it would rocket.
