We have a listing problem on our 1985 Revenge 22 W/T.(175 single Yamaha OB) Mainly with passengers moving around . I'm not too keen on Trim Tabs. The Doel-Fin folks say their stabilizer will help. Does it? I'd appreciate any advice!

I've got tabs on my 2986 22 W/T. I believe their an absolute necessity to correct the listing. The Doel Fin won't let you dynamically balance the load like tabs will.

On my 22 Outrage w/WD, I used a Stingray Hydrofoil. It corrected the torque list of the big 250 Yamaha. However, if I could have put them in, I would have installed the Lenco trim tabs in a second.

Agreed-

I have had a Doel fin and now have Lenco trim tabs on my Outrage 22. I have used Doel fins extensively on a number of boats, and I recommend them without reservation to help control porpoising and to achieve a slower planing speed. But for lateral dynamic balancing and trimming you have to go to the next step and install adjustable tabs.

Brian - does your WhalerDrive keep you from installing tabs?

Yes, the Whaler Drive does not allow for tabs. The curve of the drive from transom to side is too great, and the transom itself is too narrow. Additionally there would be nothing to "bolt through" the actualtor arms to without somehow getting through the deck of the WD and removing some foam.

Frontier -

I have a 1990 Revenge 22 (Alaska Whalers, page 44). Tabs are the only way to go. The Doel-Fin will help with your bow attitude. But Whalers respond to the wind (tilt into it), shifting people, and shifting dogs, so tabs will even you out. Mine came with Insta-Trims and they've worked flawlessly (11 yrs old).

I think I am in the minority here. We have a 20-Revenge, no Doel Fins, no Trim Tabs.

Yes, it does lean into the wind, but we have a system to fix that. If it is leaning to PORT, I tell Chris to come over and stand next to me at the helm. If it is leaning to STARBOARD, I move over to the left and steer with one hand. Usually, this will get us back on (or close to) even keel.

Now for the Trim Tab issue as it relates to trimming the bow attitude. I find that usually the best ride is with the bow running rather high. This puts the chop on the aft one-third of the hull, at the vee of the centerline/keel. I get into situations where I am blowing the props out trying to trim the engines out farther to hold the bow up, and I have to bring the engines down lower to get the props grabbing cleanly. This puts the bow lower than I would like it, and I am taking the chop on the aft two-thirds of the hull now, with the result the ride is rougher.

There is nothing that trim tabs can do here to help me raise the bow, so I don't think I need them.

What I am going to do this winter is to move the engines back on 10-inch brackets. This will help me out with the static trim, bringing the bow up a bit more, and I should get better leverage on the bow trim with the extra 10-inches of lever arm from the prop thrust vs the boat center of pitch resistance.

Also, dragging those trim tabs through the water uses some horsepower, and I need all the horse I can get as I am only powered with 140-HP.

I also agree with JimH on trim tabs, at least with respect to the 25 Outrage hull. Just doesn't need them, and rides fine in all sea conditions for me. The "lean into wind" condition can also be eliminated by twin engine proper trim, trimming out the engine on the "low" side, or trimming in the engine on the "high" side. That's what I do for a perfectly level ride.

Whoops! Got that twin engine trimming backward! Trimming in RAISES (pushes up) low side of stern, trimming out LOWERS (pushes down) high side of stern. Together, you can make a hull ride level in a cross wind with no need for trim tabs.
