M80's or M120's

[AlexT]

Bennett is going to agree that there is no harm and some benefits to going with the larger tabs, for all the reason listed above. For comparison sake, I have a 18' Parker which is a heavy boat at 1900 lbs. w/o motor, and Bennett suggest the 120s. Because my deadrise is straight and space along the transom was not an issue, I opted for the 18"x9" standard tabs, which provide more control.

What the tabs will do is allow you to go faster in the chop and keep the bow down so the sharp forefoot cleaves the waves. How fast you actually go, or if you get up on plane, is a function of the seas at hand and what you consider comfortable.
