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 тАФ per engine.
WHAT IT DOES
тАв Engine-hour due tracking тАФ oil and filter, impeller, gear lube, fuel filters, spark plugs, each measured against the interval you set from your manual
тАв Independent hour clocks for twin and triple engines тАФ the port impeller can be due while starboard still has hours left
тАв By-time items тАФ annual service, winterization, anode and zinc checks
тАв Saltwater items тАФ post-trip flush reminders for boats kept in salt
тАв Safety-gear expiry dates тАФ flares and extinguishers, tracked from the dates you record
тАв Service records with photo receipts тАФ date, engine hours, cost, shop or DIY, parts, up to 3 photos per entry
тАв Winterization checklist тАФ an editable template you reuse each season, saved per boat per year
тАв Cost tracking тАФ total spend, spend by system, and cost per engine hour, with per-currency totals
тАв Service-history PDF тАФ the full log with photos, ready for a buyer or a marine surveyor
тАв CSV export and JSON backup with restore
тАв Works fully offline тАФ 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 тАФ 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.
