MyBoatWorks is a boat management and maintenance app built by cruisers, for cruisers. Designed for both sailboats and cruising powerboats, it gives boat owners one trusted place to organize equipment, track maintenance, manage spares, record fuel and water usage, store documents, and keep up with the countless details of life aboard. Whether you manage a weekend boat, a racing boat, or a long-range cruising vessel, MyBoatWorks replaces scattered notes, spreadsheets, paper logs, and memory with a practical system designed for real-world boating. Share access with a spouse, co-owner, or crew member so everyone can view and update the same boat information. KEY FEATURES • Equipment Tracking Build a complete inventory of onboard equipment and systems, including engines, pumps, electronics, batteries, safety gear, dinghies, outboards, and more. Store manufacturer, model, serial number, installation location, photos, notes, and supporting documents for quick access whenever you need them. A built-in Starter Equipment Catalog makes it easy to add common marine equipment without starting from a blank screen. • Maintenance Scheduling Create recurring maintenance schedules tied directly to your equipment. Track service intervals by engine hours, calendar time, or both. Quickly see what is coming due, overdue, or on track. • Maintenance Logs Record completed maintenance and repairs with dates, engine hours, detailed notes, parts used, and service history. Quickly answer questions such as: “When did I last change the oil?” “Who worked on the engine in La Cruz?” “Did we replace that impeller already?” • Spares Inventory Management Track onboard spare parts and consumables, including filters, impellers, oils, belts, and service kits. Low-inventory items are highlighted and added to your shopping list, helping you restock before the next trip or passage. • Storage Locations and Stowed Items Create named storage locations throughout your boat, including lockers, cabinets, bilges, lazarettes, and other spaces. Record what is stored in each location, along with category and quantity, then use fuzzy search to quickly find items aboard. • Fuel and Water Logs Record fuel purchases, water fill-ups, operating costs, tank usage, engine hours, and other details to build a useful historical record for your vessel. • Tasks and Shopping Lists Capture repairs, inspections, projects, reminders, supplies, and gear purchases the moment you think of them. Track task completion dates, undo accidental completions, and keep priority items visible from the dashboard. • Boat Profile Store essential vessel information, including registration details, propulsion type, engine information, ownership information, and important identifiers in one convenient location. • Notes and Documents Store manuals, receipts, service information, photographs, and other documents where they matter most. Keep supporting information connected directly to your equipment and maintenance history. • Bulk Web Import Use a desktop keyboard to add equipment, spares, and maintenance logs through the MyBoatWorks web import page. Imported information appears automatically the next time you open the app. • Dashboard Overview The Home dashboard provides a clear snapshot of your boat’s status, including upcoming and overdue maintenance, low spare inventory, yearly expenses, recent activity, quick actions, and priority tasks. • Data Export Export your boat data—including equipment, maintenance logs, schedules, spares, fuel, water, engine hours, and more—to a dated CSV file using the iOS share sheet. BUILT FOR REAL CRUISING LIFE MyBoatWorks was created from years of hands-on cruising experience and designed around the way boat owners actually manage their vessels. It focuses on simplicity, fast information capture, and having the answers you need when and where they matter most. Your boat. Lives here.
