My comments were relative to a Pogo style boat vs heavier and rounder boats.
In light air on a wide boat, you get the feeling of being "stuck", then suddenly the boat becomes alive, IME rounder hulls don't show this behaviour, they just accelerate smoothly and thus initially are at an advantage. If you aren't convinced take part in an IRC race where there is a mix. I hadn't realised that the carbon cutters didn't have that much sail area for their weight, so yes may be it will hard to exploit their "slipperiness" in light air.
Upwind in confused seas, I've seen heavier boats of moderate beam, barely slowed as they charge upwind going "through" waves, on a lighter and wider boat it can soon become a "stop and go" scenario which obviously isn't very efficient, hence my comment.
In others conditions at a similar length, the rounder and heavier older designs can't compete. There is a reason why their TCC is lower LOA for LOA.
It is mainly observations while sitting on the rail during semi offshore races like Cowes-Dinard where you can witness stuff like a Swan, a J boat, a X a Pogo and a JPK racing each others.
I don't think that I've said or inferred somewhere that the cutters were designed to plane, VPP may not have a column for "confused sea" but when you are out on the water it matters a lot whether waves are coming from several directions or not.
Bob, you are doing a poor job at pretending to ignore me.
What on earth does a POGO have to do with these 50'+ cutters?? It's like comparing the handling on my new Maxima with those of the 90' Kenworth I just passed on the highway.
I gotta find the ignore button.
