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?

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 .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 , 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.

Hi I am 14 years old and very interested in the Americas cup, and have been wanting to build a rc model of the AC45 for a long time. Is there anyway that you could please send me the plans for the model that you made? I would also appreciate any tips that you may have, and where you buy your supplies. Thanks!

Hi. I would love to get a copy of the files for this boat. I have been following your work on one of the R/C forums too. I have a friend who can cut the panels on ABS sheet and i think he would be interested in building one as well. What thickness do you recommend?

Dan Elliott (author)  F_R_D1 year ago
When I get back in the office I will sent you a PDF and DWG of the Black Cat.

Dear Dan,
Would you mind to send me the templates for the wingsail and hull. I am a model "yachter" and am very interested in creating a "mini AC45" as you have. Also, what CAD app do you use?
Dan Elliott (author)  us173561 year ago
No problem, send me an e-mail and I will send you a PDF of the CNC line work. I can also offer you the same line work in AutoCad 2004 if you like.
us173561 year ago
