Galley Headliner Leaks

In the midst of the worst torrential downpours Key West has seen since the 1800's, and they've had a lot of downpours in the intervening years, we get serious about finding the source of the leak(s) in the galley's headliner. We drop seven planks and discover there are actually two leaks. The most water is coming from the wire bundle penetration inside the stack. This will be an easy fix. The second, smaller leak, is just to port of the first but still under the stack. I'll caulk the stack to the pilothouse and also rebed the four stack mounting bolts. The headliner has some water damage but replacing a few planks should take care of that. The trick will be matching the color and grain. Quarter sawn maple is supposed to be a good approximation for the grain.
