This design is a semi scale model of the yacht that won 2000's Louis Vuitton Cup in Auckland. I designed it with either look and performance in mind. The sail plan is suitable for light winds. 

The trick to have a fast boat is not to exceed the given displacement and to try to make the hull as light as possible. In this way it will be possible to put more weight in the bulb. Fiberglass is recommended in building the hull but a balsa planked hull will do the job as well. 

You may take a look at my finished model in the Models  page. Enjoy it!

I updated the design with some minor changes: i moved slightly backwards the rudder to have better manoeuvrability, modifyied a little the stern shape (now it's more like the real thing) and the sailplan. The plan includes now a detailed deck accomodation to allow scale details to be added.

Specifications:

• scale: 1/20
• Lenght over all: 1.195 m
• displacement: 4 kg
• bulb: 2.5 kg
