I know the sailboat in the below link doesn't meet the Hawaii requirement, but I've been looking at it...a friend of mine owns one and it is a joy. The wind here on the Chesapeake is mecurial in the summer. It is really nice to purge the ballast and run home on the 50hp outboard at 20 kts
The purists may howl, but it is a great way to learn.
