Just my two cents but after sailing on more boats than I can remember since my Dad first took me out in 1954 I have never seen a boat that that is not uncomfortable under some conditions; and most boats can be comfortable under other conditions.
No question cats do have an issue with bridge deck
slamming; but the standard solution is to fall off a few degrees. Problem with that is in some conditions like confused seas this may not solve the problem. Another big issue for me is living in Florida
I have been in the Gulf Stream
with a North fetch in the wind (especially in 15kn plus) and the square waves this wind direction against the current
produces is uncomfortable in almost any boat I have seen.
On the other hand as was noted earlier if the wind direction is for a broad reach in many boats a quick cat will have the apparent wind move far enough forward that you will be on a maybe a close reach. But my experience has been that by falling off you speed increases enough that your VMG is as good, and sometimes better, than sailing closer to the wind; not to mention a much more comfortable ride.
Bottom line is any of the boats in the vid could be very comfortable if the skipper
wanted to alter the course for that reason; or in the alternative none of the boats would be comfortable under the Gulf Stream
square wave conditions.
As an aside there have been multiple threads that discussed cat v monohull comfort on passages. The consensus seems to be cats are less taxing in part because they sail flat and as a rule
are faster. Another big plus for cats is moving around on deck
; especially going forward is usually much easier on a cat as there is a lot more deck space.
Most important thing I have learned over the years is that there are boats that seem to fit people. I am 5'8" so over six feet of headroom
is a waste for me. On the other hand I am in the water
almost every day when cruising so ease of entry and boarding on the sugar scoops is mandatory. While I get it that self tacking jibs cause a performance hit as a single
hander they are a must. Without listing every thing I look for in a boat I would point out that my list is not the same as the guy in the vid so his boat would not fit me and vice versa.
Only way to know which boat is right for you is get on it and sail it.
