No such thing as forward rake, Meaning beyond vertical. No boat will point well with the mast forward. The question is Deg of rake relative to it's design,For instance I believe j boats use a lot of rake,105's use 20+ inches because the mast is ahead of the keel thus if the mast were left straight there would be too much lee helm.
As I understand it more rake = more helm and I'm struggling to find that balance. In our case we now have 12" of rake but the rigger accomplished this by adding 3 toggles in front and shortening the back stay.(Not good) I now have what I believe to be a little more rake than needed and the foot of the sail is 10" or more off the deck at the tack and several feet at the clew, so much for the "end plate effect". We raced the other night with this set up for the first time and finished 7th when we've never finished below top 4.
In my case the heavy rake induced some helm,enough to point better, but the lifted Jib was under powerd so we pointed without speed.
In any case it's never desirable to have the mast leaning forward.
