We have had a lot of broaches during the years bit this one was the worst, it were actually 2 broaches in one. Just at the last gate at shore...... We made a wonderful gybe on sea before coming in where we kept planing full speed through the whole gybe.
I blame it the balls of the rudder bearing, they are probably square now. I was at the helm race before and the rudder got stuck sometimes at one side under pressure.
We even lost a runner out of the mast during the broach. I still hear the owner saying please guys don't sink the boat.... ehh yea we're on it...who the fuck put a figure knot in the tack line..... knife!!!! pffttt adventure hahahahha.
