Warbird:
There is a whole chapter on the H-17 buy one of the best Carlton Tucker in "Catamaran Racing for the 90's". You can get in from the Online store here. Boom is MUCH better and allows you to setup a mast rotation system, that it REALLY needs. I enjoyed mine for 6 yrs, before I got the Mystere 4.3. Learning spin to get ready for the Blade someday.
