Two Lucky Fish here, we're at the outboard end of P dock, uncovered. I raise the engine out of the water and rinse it with fresh water every time I leave. I use a dilute solution of Simple Green to get gunk off the boat. I own a trailer, but don't have a place to store it. I go fetch it from my buddy's lot when it's time to pull the boat for maintenance.
My boat's 3.5 years old, and it's about time for new bottom paint. The aluminum trim tabs look like a lab experiment. I'm hoping to find a yard that goes through enough $300-a-gallon bottom paint for aluminum that they can spare a few tablespoons for my trim tabs while they paint the rest of the hull.
I left my little electric heater on during December, due to some
cabin flooding that was drying out. But I'm not going to keep it on this month...I want to see what the difference is.
Zincs: They still look fine to me, so I leave them as-is. Of course, with the motor up, there is very little metal in the water...mostly those dang trim tabs!
Let me know if you want to go out and practice docking. I'm sure Sarge and I can help you put a few new dings in your gelcoat

Seriously, you can practice on the guest docks, where you have a little more room. Perhaps I can explain my "Asteroids" theory of C-Dory maneuvering.
I was really intimidated by docking at first, but not anymore. I don't claim to be any sort of expert, but I seem to be able to get the boat into the slip, which is only 9" wide on the north side of P-dock, without causing damage to the boat, the dock, or my neighbor. So far. Knock on wood.
