Trim Tabs

Do trim tabs help the performance of a boat by making the hull length effectively longer?

Nick.

Yes. Along with much added control in choppy conditions.

Longer and they obviously can change the angle of the hull with the water depending on how they're adjusted.

Thanks for the replies.
What about the likes of smart tabs or automatic tabs. they seem to be cheaper, but is there a down side.

Assuming you mean the non-adjustable ones?

They are very useful on small inflatables, helping to lift the stern and lower the nose. Perhaps they would also have some benefit for small RIBs but not with much more than 30hp. They would simply act as an extension to the hull in this case. Adjustable tabs are not really necessary on a sub-150hp boat but they are absolutely excellent.

Gotchi, do you have any actual hands-on experience with Smart Tabs or the like?

Yes, our Zodiac tender doesn't have them but I have used one that does and can therefore comment on the difference.

Also, we have electric trim tabs in Into The Red, Erin didn't on La Frette.

I was wondering if they would make a 5 to 6 metre boat perform better or give a smoother ride in lumpy water like you get in the solent.
Adjustable tabs, about 400 to 500?

They would, and if you can justify the outlay then they will make a huge difference. Erin is the one to speak to on cost but I think that would be top end.

La Frette tab'd

But don't believe everything he says about trim tabs, he hasn't even had his strengthened!
