Based on what I see around the dock, and what I have helped others with there are some things that cost nothing to not much that will save big bucks in the long run. No doubt others will be able to add to this list
1 Exercise through hulls so they don’t freeze up
2 Engine - change the engine oil and filter.
3 Prevent corrosion – keep zincs underwater and in the cooling system in good shape
4 Fix deck leaks before they cause rot
5 Prevent corrosion – use a corrosion inhibitor on engine mounts, stern tube, electrical wiring,
6 Replace hoses on engine and elsewhere before they fail
7 Prevent sun damage – put the shades on the dodger and covers on the sails
8 Prevent sun damage – protect the dinghy
9 Prevent sun damage – protect the binnacle and electronics
10 Change out hose clamps (and double clamp) before they corrode out
11 Engine – change the transmission fluid
12 Engine – Change the coolant
13 Service the winches and windlass
14 Clean the bilge, keep foreign bodies our of the bilge pump(s)
15 Service the head
16 Portlights – replace gaskets, lubricate dogs, re bed before you damage by forcing and they leak anyway.
17 Wiring – secure before it chafes
18 Halyards and other – quiet before they wear and/or your neighbors shoot you
19 Booms – prevent them from “wagging” so the goose necks, sails, sail covers and sheets are not wearing right at the dock.
20 Don’t slam her into gear or from forward to reverse with the engine revving too high
21 Replace the “fan belt” before it breaks
22 Don’t let your shore power cause electrolysis
23 Check your dock lines
