Ken,I've always been a fan of aerodynamics. Anything that may have any affect on attempting faster travel of anything... That being said... John Finch did an article on pushing a mono hull to higher speeds. You may or may not know about that article. In any case it's well worth reading. And, if you've read it before it's worth reading again! I have to admit some of what he found surprised me more than once... It's in Advanced R/C Boat Modeling. Published in '92 and republished in '94. Sorry, I am NOT a fan of mono's. But, I found this well worth reading! Chapters one and two.
I am glad to be of help. I have learned so much since that book was published and still learning. last weekend me and my buddy Steve got to put the concepts of weight, cg, rudder placement and prop design to work, and after 5 hours of constant testing we gained 11 mph on his mono saw setup. Things change every 10 mph gain in speed and aerodynamics is a big part of it when only one inch of the boat is touching the water.
