I just purchased my 2019 130 SUPER SPORT, and I truly enjoy this skiff.

Q1: Have trim tabs been put on the transom of the 2019 130 SUPER SPORT?

I don't think trim tabs have often been installed on any 13-foot skiff. A small and light 13-foot boat is sensitive to placement of crew weight. A slight adjustment in crew weight location will generally have a significant influence on trim on the boat, both lateral and fore-and-aft.

A waste of money if you ask me. Boat is too small and subject to loads moving around that trim tabs are way too excessive for the benefit

Question: What problem are you trying to cure with trim tabs?
Is the rear “squatting too low” at certain speeds? Are you unable to bring the bow down at lower speeds?
Are you trying to level out one side versus the other?

I recommend new owners use their boat for a season before doing any mods/upgrades. Gives you a chance to refine what you want.

The boat has a slow advancement to achieve planing speed. Sits bow high for a 5 to 7 second period. Thought permanent tabs would lengthen the hull overall and create a longer stable platform for the hull to achieve a quicker plan. Been boating for 40+ years. This 130 SS is more a small boat than a skiff design.

With two soles on board, the fuel tank mounted under seat in the factory location, and no other weight added, this hull should not bow ride as long as it [does].

If I were able to shift weight I would agree with your comment. I have noticed several other 13-foot hulls have added tabs, not power tabs but permanent plates and was looking for responses as to how they had either improved or made no significant change. Thanks

When accelerating onto plane with your 2019 130 SUPER SPORT with two people aboard, are you setting the engine for maximum down-trim? If yes, and the bow rise is still too prolonged for your liking, you should contact Boston Whaler for advice on this new boat.

Boston Whaler should have some remedy for this problem if the cause of this prolonged five to seven second bow rise during transition onto plane is a defect in the hull design.

I am curious: in your view, how long should the duration of the bow rise while transitioning onto plane be in order to not be too long?


ASIDE: when referring to the number of living people aboard a vessel, the usual unit is "souls." If you were to count "soles" you would have a number that was two times greater than the number of living people aboard, unless some of the people aboard had lost a foot.

With experience in several small Whalers, I would recommend adding a hydrofoil to the anti-ventilation plate.
There are one or two available WITHOUT drilling holes in the plate. Drilling 2 holes never really bothered me because the hydrofoil worked so well that they became permanent.
The benefits were: quicker to plane, and ability to stay on plane at lower speeds, and less “squatting”, and less bow rise.
Many times it gave a much better ride in choppy slop because you could plane at a lower speed.
The one I used on our 13 was a Sting-Ray Jr.
Worked for me.
