WHY TRIM TABS?

Improve the performance of your vessel by adjusting the running angle of your vessel. Trim tabs help reduce bow rise, get you on plane faster, correct listing, improve visibility, and increase efficiency

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

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)

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. I 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, i generally point you to use the premier or high-performance systems.

In a nutshell , getting the right sized tabs will help improve the stability of your vessel and efficiency !
