I found out the other day that my trim system is woefully too small. I have hyd. 12x9 tabs on a 29 ft Proline. Bennett recommends 18x12 with down fins on the side due to the limited stern area available to add larger tabs. Bennett doesn't make trim planes with larger than 12" chords. However, for those of us who have heavy dual I/Os with limited trim span areas, perhaps a 14" chord might be even better. I can get larger ones (18x14) made at local fab shop, but Bennetts have always been the chosen trim makers. Any suggestions???????.
