This is a Wing Sail Catamaran project that I started over 4 years ago after seeing the new AC 45s introduced to the America's Cup races. The model uses PVC sheet, Carbon Fiber tubing and 377 Dupont Mylar to "skin" the wings. The "Cookie Cutter" construction technique allows me to make quick inexspensive changes to the design without having to scrap a model and start over, everything is tweekable. Two Catamaran models are shown here, but I have created a total of four boats during design development, one of which only sailed once,and poorly. But that one sailing taught me alot, and I started another boat the next day. It's not all about finishing one boat, it's about developing a Platform that can evolve as you learn.

Hi Dan,

I think i may have communicated with you before on other forums but I am sixteen and making a four foot long, roughly 2 and a half feet wide and over six feet tall (the wing itself is six feet) model Americas cup foiler. I have made the wing and will be starting on the hulls as soon as I can. I think you will be very interested in my foil system, my boat will be able to adjust the rake of the foils and instead of doing it manually I am going to have a raspberry pi automatically adjusting the rake for most efficient foiling. Do you have any tips for me?

Dan Elliott (author)  sumneros2 months ago

Hello Sumneros,

Sorry it took so long to reply to your message, I've been away.

The best advice I can give you is, keep a blog of your experiments and share everything that happens, especially the failiers. Take lots of pictures. Check out Jonathan Everetts attempts to create a foiling wing sail catamaran. That is his cat shown in the photos above. Put a GoPro on it if you can.

Hi dan, I've found some info and pictures online of the amazing rc wingsail catamaran you have made and would be really interested in building one myself or ordering one of the kits if your still making them, could you please send me the plans and drawings for it to see if I'm capable of doing it myself! To leesaunders1987@yahoo.co.uk .Could I also get some more info on the kits what they include and what I would need, many thanks. Lee saunders

I am currently producing a run of (10ea.) kits, (3ea.) are sold, one to the Univ. of Michigan. If you would like to purchase one of the second gen. Black Cat model kits please send me an e-mail delliott@1220.com , The future intent of the Black Cat platform is to utilize rapid prototyping tools to create retofitable foiling configurations for the dagger board well and rudder assemblies in order to test new foiling designs.
