Frenchie,

Wouters comments were in reply to my thread "speed!", I was actually more interested in the cat speed compared to wind speed, but asked about top speed out of curiosity.

The reason I asked the question is because I am considering putting a biplane rig on my cat. And it struck me that a biplane rig would only work well if the cat was able to sail faster than the wind as this would mean the apparent wind would be unlikely to result in one sail masking the other.

Indeed I think the fastest boat at Weymouth was a biplane rigged trifoiler.

Now that this thread has got so much attention from so many knowledgable people what do people think of biplane rigs on beach cats?
