Talk about BS'ing...Surfesq, "A full keel boat is more comfortable" ? Where do you come up with this stuff?
There is absolutely no relationship between a full keel and comfort. It is true that many a boat that is comfortable for offshore work has a full keel, but its not the full keel that makes the boat comfortable. Motion comfort comes from a cluster of factors that revolve around a boat's buoyancy and weight distribution, and dampening. Keel shape may come into play on some specific design but from a motion comfort standpoint a full keel offers no specific advanage and infact can offer disadvantages in terms of absorbing greater impact area for its weight.
You might argue that a full keel provides better directional stability, which is more often true than not, but motion, forget about it. No relationship at all. Sorry Dude.....
