I have a pair of SmartTabs on my trailer boat to keep the bow down to cut through waves easier. The boat is light and rode up and over the waves too much. I had a cutty cabin years ago that was back-end heavy and was hard to get the bow down. It also porpoised a bit. I tried a fin but that didnt help at all. I wish i knew about the tabs then as they work great. Theyre about $150 and easy to install. The manufacturer has different models depending on your boat.

Ps. The tabs have a piston that extends the tab down until water pressure builds to compress the piston and push the tab up.
