Adjustable Trim Tabs
I designed my Convertible trim tabs for people that were not sure if they wanted electric tabs, or didn't have the money right now for the cost of eclectic tabs, but want to have an option to upgrade them later. My fixed tabs have proven that they can improve the performance of small boats, my adjustable are the missing link. They are a step above fixed tabs, and a step below the electric tabs.
When you are ready to upgrade, you simply replace the turnbuckles with actuators.
