Hi Pepin,
Ah, but I do have the exact dosage for you. Check out the Super Wave.

With this rig the boat is almost as fast as the Hobie 16. I won first overall (60 boats, most with spins) at the last Round the Bay Regatta put on by Mike Fahle at LaSalle, MI, took 2nd in the Conch Cup in Miami, FL, (about 40 boats.., lots of spins, Marstroms, A-Cats, H16s, et al), Won the Sandusky Steeplechase, and the list goes on.

Hot set up. And Chris.., if you really want a youth trainer boat, this is it -- small, cheap, fast, double-handed (if you want) and a great lead-in for larger, faster, expensive spin boats.

I had been working on the SuperSuperWave. I used a nine foot bow sprit, had a pretty large self-tacking, roller-furling jib tacked about midway out the pole, with a roller-furling Hooter on the end.
At the Sandusky Steeplechase a couple years ago I was keeping up with Rick Roten's Hobie 20.
Keep in mind, the boat has tremendous buoyancy and can handle unlimited power (Great F14 platform) sort of like the International 14.
It was absolutely skipping across the water. With the Hooter angled out to the end of the3 9-foot pole, it created a tremendous amount of lift.
Alas, it all exploded.., or imploded. Needs a heftier bow sprit. Still have the sails, but have not returned to the project as there are so many other projects going on right now.

And money is getting scarce.
Rick
