## What is HullKept?

Every season, the same questions. When did I last change the impeller? Is the boat winterized properly? What did the yard actually do last November?

HullKept answers them.

A GUIDED WINTERIZATION, FOR YOUR ENGINE

Not a generic checklist. HullKept asks what you run — outboard, sterndrive, inboard or sail auxiliary — and gives you the steps that actually apply. A sailboat with a diesel auxiliary gets saildrive and stuffing box checks, not spark plug fogging. An outboard gets flushing and trim-down storage, not engine block draining.

Work through it at your own pace. Mark steps done, skip what doesn't apply, add notes and photos. Quit halfway and pick up where you left off — the boat isn't going anywhere.

KNOW BEFORE THE FREEZE

Tell HullKept where you keep your boat and it works out when your first hard freeze typically arrives. You get a reminder with time to act, not a notification after the block has cracked.

SERVICE INTERVALS THAT MATCH YOUR ENGINE

Maintenance schedules differ between engine makers, and HullKept carries intervals for eight of the major ones across outboard, sterndrive, inboard and sail auxiliary. Items track hours and calendar time together — "100 hours or 12 months, whichever comes first" — the way the manuals actually write them. Anything HullKept doesn't have a schedule for, you can set yourself.

PHOTOS AND RECEIPTS

Attach photos to any service. Scan a receipt straight into the record with the camera. Years later, that history is what proves the boat was cared for — to you, to an insurer, or to a buyer.

BUILT TO STAY YOURS

No account. No sign-up. No servers. Everything lives on your phone and works offline at the dock, in the yard, or out of signal. Export a backup file — photos included — whenever you want, and restore it on a new phone.

FREE, AND FAIR

The whole app is free for one boat: full maintenance log, history, photos, freeze alerts, due reminders, and one complete guided winterization run, start to finish.

If it earns its place, a single $14.99 purchase unlocks every run after the first, additional boats, and backup export. One time, no subscription, yours permanently.

WHAT HULLKEPT ISN'T

It's not a replacement for your engine manuals or a qualified marine technician. Intervals and checklists are general guidance compiled from manufacturer schedules — your own manual is always the authority, and conditions vary by engine, water type and climate.
