What happens if you are fitting your rudder at 11pm, and trying to get the bolts for the rudder shoe to line up with the hole in the hull, and you are using black sikaflex?
PS Snow Petrel is back in the water at last I had a small window of opportunity to get access with the hoist, so after a late night after work and early morning fitting the rudder, prop and seacocks, I launched at 7am. Yippee
