So with the Getaway tipping the scales at 390 pounds (177 kg) and only slightly slower than the Dart 16, I suppose Hobie USA has done as best that could be expected, performance wise. They certainly have found a niche with a stable craft with a high payload capacity. In regards to "the majority of sailors don't care about performance", seems like a catamaran has to be one of the logical choice if you do care about it, so I'm not ready to sluff it off as not applicable.

Is the material and moulding process such that durability suffers with lighter hulls? Could not lighter and more refined shaped hulls in addition to a larger rig, without the complexities of a high performance mast and daggers, produce a boat capable of a 10% speed increase?
