After reading several other posts I am not sure which would be better, Hydrofoil or Trim Tabs (no specific brand is important, since opinions vary). On full Throttle the front of my boat comes out of the water about 2-3 feet. This is with me, my two sons, and tackle, in the seats. The top of my transom is just out of the water. It never planes except at half throttle. Before anyone asks neither I nor my sons are over weight, about 300 pounds total. I moved my eldest to the bow but that made little difference. If it is tabs should they be adjustable or fixed?
