They should be just far FWD enough to clear the mounting
plates for the forward cross beam thru bolts. Also make
sure the bulkhead has a drain cut out at the bottom to let
any water drain. This does two things, it reenforces the
cross beam stress area as well as stiffening the hulls for
less "walking" when cutting waves. This (I think) was
done on the P19's made after 90 or 91. I know there is an
aft bulkhead on boats made after 90. But I am not sure about
the FWD ones. I had mine done after watching stress
fractures appear on two P19's in my area that went to an
MX rig.

Mr. Dobbs is correct...and I stand corrected. The spin I got
was a tornado spin for a T sailor made by Smythe. BUT, it
turns out it was a special order oversize kite...which I am
having cut down for controllability.

A square top main, with a standard size jib and a 24 to 26
square meter spin will bring your D-PN to 64 and change.
Sailed properly (which I am still learning to do) it will
wax N20's....seen it done
