    I want to do a slightly larger version of the WETA, 18 feet long.

    The reason is as follows, and is maybe ambitious from a design point of view:

    The amas on their own make a beach cat.

    A short(5500mm LOA) central hull added makes for a turbo version of the WETA.

    Replace the racing hull with a slightly longer cruising hull and you have a micro coastal cruiser.

    All versions use the same rig, aka's and ama's. The rig is from a Prindle 18, 20 square metres of upwind sail area. A nice blank canvas (pun intended) to start with.

    I have this rig, thus my interest in doing it this way.

    Of course the structural requirements of a cruising boat on the open sea in heavy weather is different than that of a light racing boat intended for use on protected waters, and this is where the biggest design challenge lies, and also the largest compromises will have to be accepted.
