Started on Plumbing

Added anti-freeze to engine. Looked around at the hoses to count up clamps I need and figure out where stuff goes. Started to rain to quit early. I noticed the head sink and galley sinks through-hulls are frozen. It looks like they haven't been serviced in many years. Some may need to be replaced. This is more than I can take on at this time so we should put it on the list. I will get some emergency through hull plug stoppers so if one fails while I'm on the boat I can save the boat easily.
