Stability Curves

(The fwd end of the inserted rod storage in the gunnel. ) This helps to provide stability so the tower can't overpower the flat stability.

Hope this helps.

Thank you ! the tower is about 70 lbs and stands 4 feet above the rail . She is a good wakeboard boat when she has full ballast tanks ( 1200LBS +-) but i dont run with them full unless i have some one on the tower. I Also have 2 wake speakers on the tower as well but they weigh nothing (8 lbs for the pair). I will try to find 60lbs of lead soon before i have to get her ready for Key West Race week in Late January
