About
Seaworthy is a maintenance logbook for your boat on iPhone and iPad. Photograph a part on board and the app recognizes it on your device, reads labels and expiry dates and creates the entry. Set the service interval once and Seaworthy reminds you before the work is due.
PHOTO IN, ENTRY OUT
Point the camera at a part or pick a photo from your library. Apple Vision text recognition reads labels, serial and model numbers and expiry dates. An image model on your device sorts the part into a category: engine, rigging, safety, hull, electrical, plumbing, navigation, interior, tender or other. If a part is not recognized, you enter it by hand.
REMINDERS BEFORE SOMETHING FAILS
Plan each task by date, by engine hours (for example 100 h or 12 months, whichever comes first), at season start or as a one-off. Choose the lead days, for example 60, 30 and 7 days for safety equipment, and the time of day. Mark a task done or snooze it for one week right from the notification.
YOUR BOAT AND EVERY PART
Store type, manufacturer, model, year, home marina, HIN, length, draft and engine hours. A starter maintenance plan for your boat type gets you going. Every item keeps photos, documents such as manuals and receipts, serial and model number, expiry date, notes and its full service history.
A LOGBOOK YOU CAN SEARCH
Every completed service is logged with date, engine hours and cost. Search the full text, including text read from photos.
CHECKLISTS, SPARE PARTS, RECEIPTS
• Checklists for leaving, arriving, safety check, laying up and commissioning, with a history of every run.
• Spare parts inventory with stock, minimum stock and where each part is stowed. Parts used on a job are booked out and the shopping list fills itself.
• Photograph a receipt or import a PDF. Seaworthy reads date, items and total on your device and suggests the cost.
• Barcodes and QR codes are read and saved as the part number.
COSTS AND EXPORT
See what you spend per period and per currency. Export logbook and costs as CSV, or the complete logbook as JSON. Send the yard a work order as a PDF.
LOCK SCREEN, APPLE WATCH, SIRI
Widgets for the Home Screen and Lock Screen and a Live Activity show what is due next. The Apple Watch app lists upcoming tasks, and Siri answers "Upcoming maintenance".
ICLOUD SYNC AND SHARED BOATS
Signed in to iCloud, your logbook syncs through your own private iCloud between iPhone and iPad. Without iCloud, everything stays on the device. If someone shares a boat with you, you can join it for free, read-only or with editing.

YOUR DATA
Your data stays on your device and in your own iCloud. No account, no sign-in, no tracking, no analytics, no ads, no cloud AI. Recognition runs on your device.

Seaworthy is made for owners of sailboats, motorboats and day boats who do their own maintenance or hand a work order to the yard. Less paperwork, more time on the water.
