Ok for starters i am not a cat lover thats for sure so lets get this one straight first......... But if a 2100 KC doesn't outpreform a 640BC in rough conditionsthen thats really poor for the KC owners as Bar Crushers i believe are not the best ride IMO.and there design for a flooding keel does not help as much as what they go on about in stability either, especially if you are comparing it to a multi hull..... I have been in a 6.4BC but not a 2100 Kevla. Only the 5.2 and 2400 Offshore. and IMO the 5.2 KC road better then the 6.4 BC so don't even ask me to compare the 2400 with it (which i believe the 2400 offshore is actually a 6.6m boat too).
Yes the BC is cheaper to maintain which i believe is why the KC is going, but not becasue of ride surely, but if so then the 2100 must be a pig to ride in compared to the others which is a possibility!!!!!! HAve you been in the 2400 or the 5.2 and if so do you think the 6.4 rides better then these?? What big boat are they looking at going to?
