Exactly, big rig helps but rocker and narrow beam makes for low wetted area which more than makes up for the short W/L. A 14' 'Britsh Moth Plus' would be faster still.

A British Moth plus now there is a boat I would buy in a minute. But I donít think any one will ever build one and I still have my doubts if a scaled up boat would work .

I wasn't really thinking of a scaled up version more a longer boat but with the same qualities that make the BM good in the light. TBH it probably exists somewhere but the closest I can think of off the top of my head is the Phantom.

Its not that hard to make a larger drifting weather boat. The difficult bit is to make one that isn't pants in any breeze at all, 'cos who wants to sail a large slow boat? The fastest boat in drifting conditions I've ever sailed was my modified Skol international Moth, and it might be interesting to try the ideas behind that scaled up. However minimal stability, and extreme difficulty in getting back on board for the heavier sailor are probably not great sales features...

Real drifting conditions are so anomalous for anything else I'm not sure its that useful a target. Even if you don't want a planing demon you at least want a boat that sparkles in a sub planing breeze. Length doesn't help in real drifting conditions, and because long and thin tends to a wetted area penalty it may even hinder. ICs are not great in the very light for example.

The Phantom has far too much wetted surface, making it great in planing conditions, and it is OK in light winds, but in a real drift, it simply sticks. Lapping one in a Firefly is satisfying!

However, as Jim says, why make a boat only for zero wind? Unless you live somewhere with very low average wind speeds, I suppose, but then waterskiing might be more fun?

Don't get me onto the 'three year cycle of speedboat ownership'.......
