Upskirt shots and check out the Wagons! Think it's a Nomad?

Last two plan drawings and when you are ready to build your own, just sign the agreement and mail it back!

Do you have the study plans for the 33'?

     That Stiletto 27 was probably nearly as much fun and sounds like you all had plenty of time with it. My Dad's boat dreams died when he got re-married while on that assignment in Japan. I eventually went to work for a boat dealer in New Orleans who had Stiletto's in stock and I had nearly unlimited use of them. We went to three National Championships in the 27 and some real adventures on them.

I have study plans for Manta 34. I will post them after I put up The Trimaran Design Center 1970 catalog. 

Yes, the Stiletto was awesome. Party platform with the front tramp and hauled ass whenever there was good breeze.

On the last three drawings you can see my fathers pencil lines to increase the cabin house and work out a folding system. He was a mechanical engineer and enjoyed designing projects outside the norm.

And this wraps up the collection. I wanted to archive it for anyone that is interested in multihulls and their history.

Hope folks enjoy it.

Interesting seeing up thread a pic of the 25' sailing to Hawaii with what looks like a windvane self steering vane on the stern.  Every once in a while someone asks if you can mount one on a multihull.  Answers are usually mixed with rare examples.

A guy in our club has an older Brown 25 that he rebuilt in his back yard.  I don't think it is demountable though. 

What a lot of archival stuff you've put out.  It might help someone out sometime.
