Boat maintenance log
One place for what was done to the boat, when, by whom and what it cost, plus the California details that are easy to lose track of: bottom paint and date, zinc checks, DMV and mussel stickers, and who holds a Boater Card.

How this works
Type into the boat record and the rows. Entries are saved in this browser only (not sent anywhere), so keep a copy: Download CSV opens in any spreadsheet, and Print gives a paper log you can also fill in by hand. Costs are added up in whole cents.
Why these fields. Zinc checks catch fast anode wear, which can point to a stray-current problem in the boat or the marina[1]. Registration renews by Dec 31 of every odd-numbered year[2]; boats used in fresh water also need the mussel fee sticker[3]. Everyone who runs a motorboat needs a Boater Card unless an exemption applies, and must carry it[4]. Slip, repair and fuel receipts are among the records the state tax agency asks for when a boat bought out of state claims a use tax exemption[5], and a surveyor's condition report lists the boat's systems and recommended repairs, which your log helps answer[6].
Pair it with the maintenance calendar for what's coming up.
