HullBook tracks every dollar, every service, every engine hour. Finally see what your boat really costs to own — so the surprises at the marina stop being surprises.
Start your 14-day free trial. No credit card required.
Marina slips, fuel receipts, service invoices, parts orders, launch fees, winter storage. Half in your glovebox, half in email. None of them add up.
When was the last oil change? Which impeller model? How many hours on the bottom paint? Your mechanic asks and you guess.
When you sell or refinance, buyers and insurers want a full maintenance history. You spend a weekend digging through three years of inboxes.
You budget low. You spend high. You tell your partner a number in between. Everyone is wrong. The number in your head and the number in your bank account never match.
Phone in one hand, coffee in the other. Snap the fuel receipt, the marina invoice, the parts order. HullBook reads it, categorises it, logs it. You move on with your day.
Quick entry after every outing. HullBook remembers where you went, how long you ran the engine, what fuel you burned. Your maintenance reminders build themselves.
HullBook tells you when the next service is due, what it will cost, and what your boat has cost you all season. One glance. No surprises at the marina.
Every maintenance interval tracked. Oil, impeller, zincs, bottom paint, survey. Never guess again.
See what you spent last season, this season, and what's trending up. Budget the next haul-out with confidence.
Every service, every part number, every mechanic. Searchable. Exportable. Forever.
Destinations, anchorages, crew, weather. Every adventure documented, ready to share or refer back to.
Auto-calculated from your trip log, or enter manually. Alerts at 100hr, 500hr, 1000hr services.

"Every boat owner I know keeps two sets of numbers — what they tell their partner, and what they actually spend. HullBook is for the honest number."
