I personally would agree with you Karl...

It would seem the design of the N20 makes it ideal for windward/leeward bouy races (small jib, high aspect main, asym spin). I think the M20 builds on this and would, in some circles, be considered a 'better' bouy boat

The length makes it a bit more comfortable in the chop compared to smaller boats, and more room = better sailing long distance. With the bigger jib, the N6.0 with spin sailplan would be advantageous. The low rear beam clearance on the N20 has occasionally lodged complaints by distance sailors

But what, in the opinion of current sailors/owners, is the 20 foot "niche". This would appear to be the place to begin to build a product/fleet around.

Kind of like building the F18-HT for the bouy niche and the Capricorn for distance (except put a bigger jib and a reefing main on the sailplan)
