This seems odd to me that trim tabs would actually show up on a forum for trawlers. I consider them about as useless as cupped propellers on a slow boat. A drag to lift issue. Most trawlers are very heavy and even if the device would lift the stern the boat probably still wouldn't plane.
Mugillicudy,
This must be something I've never seen before.
Pictureswould be very helpful ..., umless these "tabs" are nothing new. The best a tab could do is to adjust the hull for it's optimum angle of attack .. and of course it has to pay for it's own drag.
