I mentioned Hobie 16MX because there is some similarity between this idea and the Prindle 19MX. I don't know what the 'MX' stands for, but a Prindle 19MX is essentialy a Prindle 19 with a square top and a large radial-cut jib, and is much more competitive than the original design.

<br>Might be worthwhile to look into how the Prindle 19MX class was formed and possibly use that as a model.<br><br>
