Marine Keeper

Stay ahead of every oil change, impeller swap and registration renewal. Track engine hours, log every trip and save toward your next big project all in one place.

Marine Keeper is a logbook app that brings together a maintenance schedule, an educational library for maritime systems, and financial planning tools. You'll understand why each repair matters, record it when it's done, and start saving for the next one before the bill arrives. Replace spreadsheets, sticky notes and forgotten oil changes with one simple system that knows what your boat needs, when and why.

WHAT YOU CAN DO • Snap a photo of your maintenance chart and get a ready-made service schedule • Set savings goals for big projects or refits with a compound interest calculator and watch your savings grow • Track maintenance across all your boats by hours, date or season, with reminders before service, docs or renewals come due • Keep insurance docs, registrations, manuals and receipts in one searchable library • Plan provisions so you know how much food to bring on each trip • Learn how your boat's systems in the education library • Use calendar, inventory and budgeting tools built for boat life

DESIGNED BY BOAT OWNERS, FOR BOAT OWNERS Whether you sail a daysailer, own a 50-foot cruiser or manage a fleet, Marine Keeper keeps every boat ready for the season ahead.
