timucin Some guys swear by them!But Wait some of the Skater guys may post Regarding the Tunnel flaps,Get a lot of Imput before you make a move that way.

Remenber talk to the Skater Owners they will be the best ones to give you advise.

Lowering the tab increases tunnel pressure and lift by not allowing the air to excape out the back. The difference can be dramatic.

The only cat to ever blow over backwards while going in a straight line was a 43' Skater at 140mph. They put the tab down rather than up. The indicator was backwards. They put the tab down too far at full tilt and packed the air so hard that she blew over backwards.

These tabs should only move a few inches. Nothing too much. When they are set properly, they should increase stern lift.

dear Ron-p and Steve-1
I am running a small cat (28) with quite heavy engines at the back.
I think I need an extra lift?!?

*by the way Turkey has received its first 40 Skater ! I havent seen the boat but they say it was tested before delivery and top speed was around 150's
