Product Overview

12x9 BOLT System with Adjustable Upper Hinge

Properly sized trim tabs improve the performance of your boat by adjusting the running angle of your vessel. Bennett Marine trim tabs help you get on plane faster, correct listing (roll), improve visibility, and increase overall efficiency and control.

Features:

  • Get on plane quickly to see over the bow
  • Increase vessel performance and efficiency
  • Correct listing (roll)
  • Adjust the boat’s attitude for changes in speed, sea conditions, and shifting weight
  • Correct porpoising (rhythmic bouncing)
  • Controls sold separately 

General guidelines for choosing a trim tab size:

In general, the widest span tabs that will fit on the transom will be the most effective. The greater the surface area, the greater the lift. We‘ll typically recommend a 9” chord tab, but depending on available transom space a shorter or longer chord tab, or specially shaped tabs with upfins or dropfins may be advised.

As a general rule for boats with max speeds of 40MPH, choose at least one inch of trim tab span (per side) for every foot of boat length. For example, a 22′ boat would use a 24”x9”.
For speeds 40MPH and over, we’ll generally point you to one of our Performance, or Premier Line high-performance systems.

Users can adjust the boat's attitude to adapt to varying speeds, sea conditions, and shifts in weight. This product is suitable for boat owners and marine technicians looking to improve the operational efficiency and handling characteristics of compatible vessels. It addresses common issues related to boat stability and performance by providing a mechanism for dynamic trim adjustment. Controls for this system are sold separately.
