All 3 are good sea boats....if you are questioning going bigger and can do it definitely go bigger. Real 4' is not a fun day in my 31'.....fishable yes, good day to be out marginable. Real 4' seas are gonna be a swing of 4' above and 4' below flat seas and that is pretty big for comfortable fishing depending on the period.
