## What is HullBook?

A well-kept boat deserves a clear paper trail. HullBook keeps that record 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 as part of the record you create.

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.

EVERY COST OF KEEPING HER
Docking, insurance, winter storage, registration, equipment, cleaning. Log each expense with its amount and vendor, filter by category, and see totals by category and season. The cost of ownership view adds your recorded fuel and service spend beside them, and nothing is ever counted twice. Export the expense log as a CSV for a spreadsheet or your accountant.

DEPARTURE BRIEF
Open Home to see pre-departure checklist progress and maintenance readiness together. Continue the checklist in one tap before the next outing.

NEXT TRIP FUEL PLAN
Enter planned engine time and a reserve. HullBook estimates fuel and cost from your boat's own recorded burn rate, clearly labeled as a planning estimate rather than a navigation or safety calculation.

OWNER TOOLS FOR THE NEXT OUTING
Repeat the last route to prefill a new trip while leaving today's conditions blank. Forecast maintenance by planned engine use and calendar horizon. Review the fuel and service amounts you recorded for the season, including cost per engine hour when the meter history supports it.

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 PRO
Free: 1 boat, 15 records (engine logs, trips, fills, service entries, expenses), every checklist, and the full maintenance scheduler. Pro removes the record cap, allows unlimited boats, and opens the Service History PDF and the expense CSV export. Choose monthly, yearly, or one-time Lifetime access. The App Store shows your local price before purchase.

Payment is charged to your App Store account when you confirm a purchase. Monthly and yearly subscriptions renew automatically unless cancelled. You can manage or cancel subscriptions in your App Store account settings. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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