I have been experiencing a problem when beating in moderate+ winds. My
foresail is a masthead rig(?)a large genoa & really 'bangs' when
sailing close to the wind, this in turn is transmitted down the mast. I
know that the rigging is probably on the slack side, particularily the
forestay (its at the end of its adjustment at the bottlescrew), would
this be the likely cause or should I be looking elsewhere?
