marina management
Portuna consolidates berth assignments, dockage invoicing, and vessel documentation into one auditable platform — built for the boat owner and the operator managing forty slips alike.
Assign, reserve, and reconcile every slip against LOA, beam, and draft. Portuna flags conflicts before a vessel ever reaches the fairway.
Generate itemized dockage, power, and pump-out invoices on a fixed cycle. Meter reads, proration, and late fees calculate without a spreadsheet.
Track insurance certificates, registration, and hull survey expirations per vessel, with automated notices before any lapse becomes a liability.
Berth-level alerts for storm surge, low-water windows, and NOAA advisories, routed to the tenants and vessels actually affected.
Give slip holders a self-service record of statements, contracts, and vessel details — replacing the shared inbox and the clipboard at the fuel dock.
Standing reports on occupancy, waitlist velocity, and revenue per linear foot, exportable for your board, lender, or accountant.
“We managed 62 slips out of a binder and two spreadsheets. Portuna gave us a defensible ledger — when a tenant disputes a dockage charge, I pull the record in seconds.”
“I keep my sloop at three different harbors seasonally. Having every registration, insurance cert, and invoice in one authoritative place ended a genuinely tedious chore.”
“The documentation expiry alerts alone paid for the year. We haven't had a single lapsed insurance certificate slip through since we onboarded.”
Simple plans that scale with you.
For the individual owner tracking one to three vessels across any harbor.
For operators running a single marina with a real waitlist.
For multi-facility operators and municipal harbor districts.
