Dear RC Racers,

We are participating in a prestigious RC Sailing Contest organized by a collaboration between the Technical University of Delft and the MARIN (Maritime Research Institute Netherlands).The organization we present is the Delft University. The aim of the contest is to challenge engineers and students to invent creative ways to sail and of course, to win the race. We are allowed to use 4 servo’s. The race consists of 3 courses. The first course is a straight race with a True Wind Angle of 120 degrees. The second race starts with the same straight course at a TWA of 120 degrees, but the same course has to be sailed in the opposing direction (so at a TWA of 60 degrees). The third race will be a down-wind zig-zag course where the course between the bouys will be between 110 en 120 degrees TWA. The hull can only be made out of balsa wood. The appendages can be made of lead or other metals. There are no restrictions on the material used for the sail. And we should be able to build the project ourselves.

We would like to innovate our design since this contest is held every year and some things have been built a dozen times. We are at the very start of the design process. We are thinking of new concepts and ideas that have never been built before and we would like you guys to participate in this process. Do you have a wild, crazy idea that has never been done before? We have the time and the knowledge to find out if this concept is buildable. We would really appreciate your help!

With kind regards,

I have so many wild and crazy ideas about yacht design
it would take you more than ten years to realise all of them.

Please tell me more.

Haha ok I will tell you a bit more about the restrictions:

the projected area of the yacht (viewed from the side) is limited to 0.85 m^2.
This is measured in an upright, zero velocity condition. This restriction is only
valid for the part of the ship above the waterline. For the sails, the maximum projected
surface is taken.

The only material used for the hull and reinforcements is balsa wood, which may be impregnated
and glued with epoxy.

the mast and goose can be produced of polyester or aluminium.

Ballast can be steel or lead. Appendages can be produced with steel, aluminium or polyester.

We are provided with 3 servo's.

Last year, a team made a submarine sailing boat. You can see a movie of it here:

We would like to think of something that cool too!

We are thinking about building a Mono-Hull with a wingsail. We have acces to a windtunnel so we could do some tests to find the best sail configuration per course. But this is not really innovative since the concept has been used in the America's Cup. But then, on the other hand, it would be cool to do some testing with a wingsail. Anyway, we are still open for other ideas!

Did you also try this forum.

How does the sub maintain the right level below the water?
