33 / 35 is the best size . loves any kind of water you throw at it,,, In my honest opinion 30 &31 are not much more than a 26.
dont get me wrong, I LOVED my 26 but eventually I realized that, on the ocean ya need over 30 ft. to really get a good ride!
..... and 39 dominators require big power and a big dually truck.
I use my 1500. vortec max tow package ( 6.0) and it is perfect for the 35! plus all year long I dont have to drive a big bulky truck!
did I mention that the boat is always for sale!
