Re: C&C 30 MK1 Boom Adjustment
The C&C 30 gooseneck is fixed, dont consider trying to move it.
There should be a black band at the top of the mast that marks full hoist, your halyard needs to raise the mainsail to that band.
The topping lift is too tight.
Note that C&C raised the boom a foot in '77, so a C&C main from an earlier boat would be too large on yours...but I dont think that is the situation here.
Certified...in several regards...
