Today I also added the locations of my inspections ports. I have chosen an 8" Beckson screw-in inspection port for easy ingress and egress of larger items. The smaller 6" port is for access to the rudder gudgeon fittings. It is off-center due to the seat cleat that runs down the middle of the compartment from BH4 to the transom. This could have been circumnavigated had I thought about it beforehand, but I didnt, so this is what I get. Not the end of the world.
Finally, a quick look on how I glued the knees in place: Two tape covered shims held in place by clamps for vertical support, and the clamp just to weight it up against the side of the hull. Not too much weight is needed, because the knee could slide up, also, if its beveled correctly it wont slide down.
