A K-plane is a trim tab on steroids

Doesnt that really trade wide and short for long and skinny?
It's same width, and about 2' long. Some are 3' long

They extend the running surface, and react faster than traditional tabs. The really big ones have 3 cylinders and a dedicated hydraulic pump per side

Thank God now I know what I'm looking at.....

1) Why the diff colored things on top?
2) Why the holes into the bottom of the swim platform? Wire could go thu sterndrive holes?
3) Tabs should be functionally fine where they are at or what is a k tab?
#1 - I'm using lower density foam for less critical parts . . . spacers, etc.

#2 - I need to be able to reach areas inside the swim platform cavity to install bolts.

#3 Scott replied about the K-planes. . . They are more narrow, but longer. The cost is above my allowance.

For now, I'll unfasten the trim tabs and may re-locate them a wee bit further out towards the chine.
