Reading your original post, you led me to believe you wanted top speed from your rig- period. No mention of slow planing. Yes, the ‘foils will let you do this, but at a price. Look at your rig on the trailer, where your cav plate runs in relation to the bottom of the boat. If yours is normal, your cav plate is a bit below, which means its running submerged on plane. Adding a fin, irregardless of its design, creates drag, which kills speed. That drag is also stressing the cav plates, where holes were drilled to mount them. These cav plates are Castings, which means they are brittle- no warning before they break. It may not happen, but s**t happens to good people all the time. If trim tabs weren’t so expensive, they would be my only suggestion. I would say you need to decide if you want speed OR slow planing with a foil- unless you know metalwork and can fab a set of tabs for the transom.
If you have too many, AND not enough, you're a collector.
