[Alberg30] Mast bend

[Melissa Currier]

I have had the same question about approprite fore and aft position of the
mast on an Alberg.  I am used to racing on other bigger, faster boats that
have adjustable back stays and check stays for upwind and "fraculators"
for cranking the rig forward on the jib halyard when downwind under chute.

I am very curious about your findings.  It seems inverse to normal trim
and tune theory to point better with the rig forward upwind...  But maybe
that's just the way these boats go?  Any thoughts from others?

I would be curious about fore and aft tensions.  I am also curious about
how much jib halyard tension you had for the light air.

We've been battling the >44 degree pointing angles ourselves...  Looking
forward to this discussion.
