Some Comments:
When using the length of a boat to assess its comfort/ convenience levels I think it also is prudent to consider the size and mobility of the likely occupants. What would feel cramped and and uncomfortable to somebody who is say 6'4" tall, weighs 300lbs and suffers from joint stiffness might seem very acceptable and comfortable to somebody who is say 5'10" tall, weighs 165lbsand has no mobility challenges. In other words the size of the boat is not the only factor so the assessment is very much an individual one.
I also very much agree that a mere 2ft extra length and 1+ft increase in beam is (ie less than 6%) will result in a boat that seems inordinately larger. (Of course these absolute figures only apply to boats in this size range).
Also to my relatively untrained eye I do not see much of a difference when looking at photographs of the 34ft and 36ft boats. Hence my desire to "try one on for size".
It seems like I will need to increase the search area to at least something that can be accomplished in a day's driving as that would open up the Florida Southwest coastline.
OTH I might just concentrate on the 34ft vessels since I weigh about 165lbs am 5'10" tall and although having been born towards the end of the first half of last century I have been blessed with good health (so far!) and the sense to maintain it.
Once again thanks for the replys
