Anyone had experience with trim tabs on whalers? I'm thinking about installing on a 210 ventura. The factory option is 9" x 9" Bennett's. Seems small for a 21 foot boat.

Lots of previous discussion on this topic and lots of contributors here have tabs. Try searching for earlier threads in this forum as well as Repairs/Mods.

The 9x9 Bennett tabs are what came factory installed on my 21' Outrage, and they do the job well. Should be all you will need.

I agree...the 9x9's are too small IMO. Whaler takes the conservative approach due to liability issues. I'd go with 9x12's or 12x12's

Call Tom at Bennett in Delray Beach FLA. He can advise you. I'm running 10"x12" newish design Bat Wings on my 22' OR. Great action for hole shot, port vs starboard lean in the wind, plus help a ton going into a heavy chop. Service support is first rate. Recently my port rocker switch took a dump. Tom replaced it under warranty in two (2) days to my mailbox. Back in business Good luck David

I put the Bennett bat wings on my 22' OR also and love them!!! Bennett offers the very best service and warranty of anyone!! I've got some pics of mine mounted I can mail.Here's Tom's e-mail firstname.lastname@example.org

Went with Lenco 9 x 18 on my 210 Ventura in spite of hearing all the glowing reports of service from Bennett. Keep up the good work Tabman! The electrics offered too many advantages IMO for me to pass up. Top speed is now 50+ mph compared to 47/48 mph without tabs,and ride is flat and level. 210 Ventura power is 225 Yamaha OX66.

I put Lencos on my 24' Bertram Moppie. I am truely amazed. Absolutely instant response, and no pumps to fail or be in the way.

Congratulations, rapidrobert, I am pleased to hear both that trim tabs are filling the bill, and that you settled with Lencos - I have Lenco 12x12s on my OR22 and couldn't be happier if I was in my right mind. I am puzzled about gaining top end speed though; I get higher top end by raising the tabs out of the water and trimming the motor up, reducing wetted surface.
Nice to hear from another happy Lenco customer - I had begun to feel a little self-conscious with all the marketing Bennett gets around here...

Thanks for the comments kingfish. I think I would have similar results on the top speed with less weight in the rear. I will do some more testing later. On the day I tested I had a lot of fuel and a full 20 gallons of fresh water on board.

Rapid- The tabs add drag. They don't increase top end speed. Congrats on your new tabs. David

I agree about the drag and the fact that tabs under a lot of circumstances do not increase top end speed, but IMO if they improve boat attitude they can, and do, increase top end because the small added drag can reduce a bigger drag elswhere on the boat. Ever see an offshore race boat without tabs?

Offshore race boats are fitted with tabs in order to adjust for chop etc just like Whalers. They do not add to top end speed at WOT on glass. David

Of course they don't increase top end speed on glass with a perfectly balanced boat. They do add the ability, however, to trim a boat to compensate for fuel consumption, chop, etc., to keep it running at the "design" attitude for minimum drag and maximum speed under variable conditions.

Rapid- If you think your boat goes faster with tabs than without -- go for it. Makes no sense. See Kingfish comment. David
