> How well does your Ulua track while paddling, Dan? Do you use a rudder while only
paddling, if you ever paddle only? Sorry for a seemingly non-sailing question, but for some
environments paddling is a necessary evil. No offense meant to the purists ;-).

The Ulua turns on a dime. This is a great feature for sailing and fine for paddling as a single
outrigger. As a tri/double outrigger, it really wanted to wander all over. It does not have
strong tracking features as these are in direct opposition to some of the other features that a
sailboat would want and Hawaiians needed. To turn instantly is a necessity in waves–which
they have in abundance there.

As usual it is better to have one big leeboard, than two small!

Making a high aspect ratio leeboard is the ticket to success, and if
you do that in aluminium you’ll get yourself a fairly heavy leeboard,
as a thin plate will definitely flutter and bend. You could make it from
a thin piece of aluminium, wrapped around a well designed hydrofoil,
made of stiff foam, but that is tricky and a bit complex!
