I fitted Bennett trim tabs to a fast fishing boat .
I had an outboard engine but found the tabs were able to level up the vessel when the wind was blowing from either side and cross tides. made for a better trip.

But to get onto the plane i only ever used the tilt on the engine.
As I found the controlling both tabs at the same time were slower than the engine tilt.

However i have not fitted any to my rib.

There is an article in this months SB&R about tabs, written by Cookee.

I learn't something, but that's not saying much...

Hi Paul....my two penneth worth....

I have a 6.5 with Bennet Hydraulic Trim tabs fitted (admittedly before i bought the RIB and when it had a smaller OB). As someone else said, they are bloody slow to adjust, but the greatest benefit I find is being able to 'level out' the boat better when unevenly laden with divers /gear......

Paul if you read back through this thread you will see that I have already explained my reasons for Tabs. I certainly don't believe they will give me any additional speed and never intended that to be the case. For me its primarily about being able to pin the nost down into a head sea.

Took the boat out on Saturday and very happy with the setup. The tabs did not interfere with performance or attitude when retracted and provide just the right amount of extra control that I was after when running into the lumpier stuff. After the succesful trial I have sent them up to Marine Fabrications to have them stregthened as I was recommended this by Roy at Osprey.

how much did that cost. I actually gained speed wih my trim tabs fitted(probably due to wrong prop fitted) as i can get the boat to behave... only about 2 knots but better than a kick in the teeth
