    You won't be sliding a boat that far up a trailer that the tabs would (or should) contact anything.

    Every boat I have ever loaded correctly, the bunks go past the transom. Other wise it can cause hook in the hull. Granted this kind of boat lives in the water. But I will want to be able to pull it on the trailer for cleanings and travel.

    Siboatguy - you should probably look to change those swim platform bolts sooner than later - Looks like an advanced case of crevice corrosion going on. Use 316 SS replacements with ample sealant.

    Bennett recommended drop fins on my tabs. They told me it should make my tabs act like the next size larger. Turned out to be the single best mod I have done to my boat. The bow rides lower and I have picked up about 1.5-2 kts. I could still use more tab but for $34. Thank you very much!

    What size are your tabs and which drop fins did you install? Sounds like a nice off season mod.

The kit I added was Bennett drop fin DF12. I would give them a call. They can verify.

    My boat is out of the water how and I’m seriously considering adding the drop fins.
    If you take yours out of the water, could you possibly post pictures and measurements of your tabs with the drop fins on them?

    Sorry, haven't spent much time here lately. I will try to get to the boat this weekend and post a picture.
