I couldn't find much in a search.

My family had a Dingo 30+ years ago. It is a Rodney MacAlpine-Downey design and was built in the United States by Dick Gibbs. It is a 15-foot-long unirig. It has one centerboard that is literally in the center, hung off the aft crossbeam. Therefore, the mast is raked radically aft, so it looks like an iceboat from a distance.

I don't know what more I can tell you. I have some information and photos in my files in Florida, but I am in Ohio until late October. Best thing is to find somebody who currently owns one. I hear there are one or two that sail off Dunedin Causeway in Florida. And most of the ones still in existence probably are in the Michigan area.

Maybe Salty Dog Marine in Michigan has some information about them.

You might also want to contact CRAM (Catamaran Racing Association of Michigan), and they have a forum on their website, http://www.websitemagic.com/cram/

Good luck. (P.S. I loved the boat, although it was a little hard to tack because of that centerboard.)

Do you have one, or are you thinking of buying one?
