Controlling chine walk

Have you found bending the outer corners of the trim tabs effective in controlling chine walk?

no, but it helps you to not drag off more speed in the corners. considering they are bent up? if they are install direcltly in he center of the strakes the water exiting the boat hull @ speed will stabailize the hull, They dont need to be mounted close to the center where they drag in the water. the spray off the rear of the boat hull is free energy. use it...

Almost all the monos and vees I have owned chine walk to varying degree. Prather's instructions for their vees suggested to bend the outter corners of the trim tabs down to control chine walk. I want to make sure if works before bending mine.

I have never heard of bending them down on he edges. it will kill the performance of the boat,

To properly trim the trim plates. hold a 12 inch straight edge under the hull long ways with the boat & set them flush with the bottom of the boat hull. They dont even begin to work for you till you are at least flush with the bottom.

If thinking of following those instruction there in more going on with that hull than a bad Chime walk.

One set of trim plates or two sets of trim plates, splits in the midlle of a single set of trim plates. Plates to close to the Keel or Plate to far away.

More information is needed to give a specific asnwer to your Question. Size of the plates will play a key part also.

Chine walk is an issue from having the wrong strut height. The problem is usually changing it as most of the time the driveline is already stuck in place (bolted, epoxied). Try turning a smaller prop to see if this helps as that will tell you if the strut need to be raised or not. I went through this same problem with an Aeromarine Titan 21. Trim tabs had nothing to do with chine-walking.

The length of the strut is also a big factor; the longer the strut, the higher it needs to be. Ever look over the transom of a full-sized boat while it's up to speed? That would show you why it would have to be mounted higher.
