The problem

Run the marina. Not the tabs.

Operations sprawl across spreadsheets, Dockmaster on a Windows tower, paper work orders, and a yard manager's iPhone notes. Nothing connects.

8 tabs

open just to assign one slip

12 apps

before a transient boater checks in

3 dashboards

to answer "what was last month's occupancy?"

6 spreadsheets

to reconcile fuel sales tax

Teams that consolidate don't go back.

On Marine OS, the dockmaster, service manager, bookkeeper, and GM all see the same vessel — same slip, same insurance status, same balance due. That's what an operating system actually means.

Early access

We're building Marine OS with a handful of design-partner marinas

Marine OS is in early access. We're partnering with a small group of marinas, boatyards, and yacht clubs to build the operating system the industry actually needs — in the open, with real operators.

A direct line to the founder

You work straight with the team building Marine OS. The features you need get built — your feedback shapes the roadmap, not a support queue.

Free white-glove migration

We move your customers, vessels, slips, and balances off Dockmaster or spreadsheets for you — no migration fee, no data left behind.

Locked-in early pricing

Design partners keep early-access pricing as we grow. You get the modern platform at the price you started on.
