BoatLog: Boat Maintenance Log

BoatLog is an offline boat maintenance log that works the way boats actually age: by engine hours. Enter the service intervals from your own engine manual once, punch in the hour-meter reading after each outing, and BoatLog tells you what's coming due — per engine. WHAT IT DOES • Engine-hour due tracking — oil and filter, impeller, gear lube, fuel filters, spark plugs, each measured against the interval you set from your manual • Independent hour clocks for twin and triple engines — the port impeller can be due while starboard still has hours left • By-time items — annual service, winterization, anode and zinc checks • Saltwater items — post-trip flush reminders for boats kept in salt • Safety-gear expiry dates — flares and extinguishers, tracked from the dates you record • Service records with photo receipts — date, engine hours, cost, shop or DIY, parts, up to 3 photos per entry • Winterization checklist — an editable template you reuse each season, saved per boat per year • Cost tracking — total spend, spend by system, and cost per engine hour, with per-currency totals • Service-history PDF — the full log with photos, ready for a buyer or a marine surveyor • CSV export and JSON backup with restore • Works fully offline — no account, no sign-up Every interval in BoatLog is one you enter from your engine manual, your mechanic, or your own judgment. BoatLog is a logger, not a mechanic — it never prescribes service. WHO IT'S FOR Outboard, inboard, sterndrive and pontoon owners; twin- and triple-engine offshore boats; sailboat auxiliary diesels; trailer boats that also need bearing and tire checks; and anyone who services their own rig and wants the history in one place instead of a drawer of receipts.
