HullBook: Boat Log

Launch season is short. Log engine hours, run the built-in checklists, and keep the service history that protects your boat's resale value.

The boat that sells fastest is the one with a paper trail. HullBook keeps that paper trail for you: engine hours, maintenance, trips, fuel, and the checklists that get you launched and winterized without forgetting the drain plug.

BUILT FOR THE HOUR METER Log meter readings in seconds. HullBook tracks current hours, hours this season, and charts the meter over time.

MAINTENANCE BY HOURS OR SEASON Oil every 100 hours. Anodes every spring. Set each task to engine hours or calendar months and HullBook computes what is due next, flags overdue work, and sorts by urgency. Start from an 18 task stock program with real marine intervals, then tune it to your manual.

FOUR REAL CHECKLISTS, BUILT IN Spring launch (37 items), haul-out and winterizing (24), pre-departure (13), and trailering (12). Written by boaters, with the why behind each item. Every completed run is dated and saved, proof the boat was cared for.

TRIP LOG WITH CONDITIONS Where you went, who came, wind, sky, sea state, temperature, distance, and hours. Your season on the water, documented.

FUEL TRACKING THAT DOES MATH Log liters and meter hours at each fill and HullBook computes your real burn rate (L/h) and cost per hour, with season totals and a trend chart. Liters or US gallons.

THE SERVICE HISTORY PDF One tap builds a buyer-ready dossier: boat specs and HIN, current hours, the full dated service log with costs, your maintenance program state, and completed seasonal checklists. Hand it to a buyer, surveyor, or insurer.

SYNCS ACROSS YOUR DEVICES Your log syncs through your private iCloud to iPhone, iPad, and Mac. No account, no tracking, and we never see your data.

FREE VS LIFETIME Free: 1 boat, 15 records (engine logs, trips, fills, service entries), every checklist, and the full maintenance scheduler. The one-time Lifetime unlock removes the record cap, allows unlimited boats, and opens the Service History PDF. No subscription, ever.

HullBook is a logbook, not a navigation or safety device.
