Which is faster?

Personally (wis you can delete this if you wish) I think until you have raced an r/c multihull against anything in any breeze you need to stay out of the conversation if you are going to make open unfounded statements. I have personally seen a mini40 sail away from a TS2 one metre, a Jellybean Marblehead and another Marblehead in very light winds (0-4 knots).

A correctly built multihull will in my opinion as a person that regular races multi’s beat damn near anything else on the water that sail’s under the r/c umbrella.
