The problem
Co-owning a boat means a lottery in a spreadsheet, use fees on scratch paper, a maintenance binder no one can find, and the same questions in the group text every week. Every partnership reinvents the same clipboard.
Shipshape is that clipboard, done once and done right — and every boat runs it with its own name, rules, and rates.
Fair scheduling & lottery
Run your season the way your group already does it — annual lottery, rotation, or fixed weeks — and let owners trade weeks without the group text.
Check-on / check-off
Your whole paper procedure on a phone, photos and engine hours included — even with no signal at the dock. It syncs when you're back in range.
Use fees that add themselves up
Daily/weekly rates plus per-hour engine and generator charges, calculated at check-off and ready to pay. No spreadsheet, no chasing.
Maintenance that nudges you
A living log of what's been done and what's due — with an automatic heads-up before the generator hits its next oil change.
A real logbook
Where each trip went, what broke, the good nights — a searchable history the whole partnership shares, and a printable binder for the boat.
One place for the group
Owner directory, board chat, polls, and shared documents — so decisions and contacts don't live in six different inboxes.

Upkeep that's logged, not lost
Every repair, hour, and part — with photos — in one history that nudges you before service is due. The next owner up knows exactly what they're walking into.

Who it's for
Family and friend partnerships, fractional-share groups, and marina co-ops — on Powell, Shasta, Lanier, Cumberland, and any lake where a boat has more than one owner. Your group keeps its own rules; Shipshape just runs them.
From the owners
People who've lived the chaos
I've had shares in five boats over the years, and every one ran on the same chaos. Swapping a week took a dozen texts. And repairs were the worst — something would break on the lake, the next family up could've brought the part and fixed it, if they'd only known. Shipshape finally fixed all of it — logged with a photo before I've left the dock. I wish I'd had it four boats ago.
