Wwhen you tighten the shrouds on a keel stepped mast, the chain plates
are pulling up thus caving in the sides of the boat. The cabin deck is
pinched up and the partner rides up the mast.
Now imaging lots of sail up in a rough sea, those shrouds are apumpin
and that cabin top is moving up and down causing all kinds of problems
down the line.
The fix is a tie rod running from the step to the partner with a
strenghtened cabin roof. Top can't ride up, sides can't cave.
