Trim tabs

[aussie]

hi guys i have been reading alot of old posts about trim tads from what i read the seem to help keep the nose of the boat down on bad weather my last boat was a outboard and i could trim the motor down untill water was coming over the deck-- so do larger boats suffer with running with there nose in the sky i have seen alot of big cruiser riding high up front but i thought it was beacuse of the big heavy inboards and lac of driver experance this pictures i got of my v20 sitting in the water it looks really well balanced so please give me so insite on this topic and WOW there not cheap to buy

anyone no what brand these are i can get them cheap no other bits with them but i still need to no wether the will work well on my boat

I believe they are on the small side . remember even though a smaller tab will work they induce more drag and will slow the boat down . I went with 22x16 Bennets and I notice no difference in top end speed and it only requires the smallest amount of tab angle to do what you want .

No comparison - these V20's / V21's to the large deep V cruisers that ride " bow high. "

With these V runabout's, it's about using the tabs to get the cutting edge into the waves to reduce lift and slam back down - pounding as it's called.

Too much tab.........sure....... the bow will ride a bit further down and you'll eventually start taking waves. It's real easy to feel - running into a chop and just adding a little tab until the boat's riding at the best attitude.

The main idea with trim tabs is to be able to push the bow of the boat down so to get the best ride and actually use the V in the bow to cut through the waves. On some boats you can trim the engine in enough to push the bow in, but this changes the engines thrust from pushing you forward to pushing the stern up to plant the bow. It makes your efficiency go way down because instead of pushing the water straight back, your now forcing it to push the water downward to hold the bow down. With tabs you can keep the engine trimmed for peak efficiency which helps with milage, using less throttle, less strain on the engine, and since it is running at a better angle it stears easier. Then you can adjust your tabs to get the boat to run at the best angle for a smooth ride. Also they help you to get on plane and stay on plane at slower speeds which really helps out in rough weather.

My friends Verado w/Smart gauges...you can watch the mileage increase w/proper trim tab settings...I think that's pretty indicative of how effective these things are...

I feel I can push the bow down far enough with just the motor when its rough and your want to plow more through the waves. When its not rough you really don't need the bow down anyways. I'm sure its nice to have trim tabs from time to time but not sure I shell out that much money for them.

You bet you can shove the bow down with your motor, at what cost to the transom and your fuel burn. I put on the Lennco electric tabs and whined about the money it cost as well(they where less than the bennett's) but after a couple trips out and using them offshore--i would not want this boat without them. Huge difference with the trim tabs and alot less strain on your transom and drivetrain.

Aussie---Those are some heavy *** looking commercial trim tabs there-I have never seen those. Must be a downunder manufacturer.

Amen to that - the tabs make this a MUCH better running boat.

Love my tabs. It took some getting used to, but once I did, I fell in love with them.

Not only do they help with efficiency, but it's also nice to be able to keep the boat from listing when the weight distribution of friends and gear is a bit off...
