Toe'd SC 20 hulls

Post by Calum »

Any advice would be appreciated.

To keep my SC20 at the marina (which means I will sail it much more than trailering it) I have had to change its width to 10 feet from 12 feet. What toe in (if any) should I use to set the huls up at their new width. When I got the boat at its 12 foot width there was substantial toe in of the hulls (3.5 inches at least).

Hopeful

Also has anyone ever but wings on an SC20?

Calum,

The SC20 should not have any toe-in, the boat should be square (or close to it) when measured diagonally.

Thanks Matt,
Will adjust accordingly.
If I loosen the Allen key bolts at the corners where the crossbars attach to the hulls can I fine tune the toe in from there, or are they not adjustable at that point?

At the bottom of each saddle are 2 locating pins (allen screw heads) and a corresponding hole in the beam which prevent the beams moving inside the saddles.

Maybe yours got pushed in if the were not initially aligned correctly when the bolts were tightened.
