In trying to set up the standing rigging on my P-19. I've noticed that the
cabin roof is not parallel to the rest of the boat (check out how the front
hatch cover fits). I'd like to rig the mast so it is truly vertical with
respect to the hull, so it can sail evenly with respect to all points of
wind. I don't have a tension guage so I can't do it accurately by the
rigging length and tension. I thought of a plumb bob down the center of the
mast, but that means drilling more holes in the mast and it just tells if
the mast is vertical, but not the boat. Also the plumb bob should be brass
so it is not affected by the keel. If I put it in water, my weight will
shift the hull all over the place. Could I get a good level line by leaving
the boat moored in calm dirty water for a few days? What is the best
reference on the hull for level and how can I get this whole thing straight?
