Best Marina Management Software for Slips and Moorings (2026)

Good marina software tracks every slip, mooring and rack with its size limits, bills seasonal and transient agreements, and lets boaters pay online. For marinas that live on transient bookings, Dockwa pairs a boater app with slip, dry-stack and winter-storage tools. For full-service yards that also repair and sell boats, DockMaster and Storable Marine (Molo) cover the service department as well. MARINAGO from Scribble Software lists slips, moorings and land storage in one cloud system. Proprietio fits marinas that want per-foot agreements, waitlists, fuel, shore power and a real general ledger in one place. For European harbours and international marina groups, Harba and Marina Master are built for that.

Proprietio publishes this guide and includes its own product — we say where it fits and where it does not. Every other vendor is described from its own website, linked.

A 40-foot slip cannot take a 45-foot boat, a mooring field has no dock to walk, and a dry stack runs on a launch queue. Below: the 2026 tools, sorted by the marina you run.

TL;DR — the verdict for marinas

• Transient-heavy marina that wants boaters booking online: Dockwa.
• Full-service marina with a service yard, parts and boat sales: DockMaster or Storable Marine (Molo).
• Slips, moorings and land storage with online booking: MARINAGO by Scribble Software.
• Slips, moorings and dry stack with the books inside the same system: Proprietio.
• Harbours in Europe or marina groups outside the US: Harba or Marina Master.

Quick-pick by situation

• You run a mooring field and seasonal slips → MARINAGO, Storable Marine (Molo) or Proprietio. All three name moorings on their own pages.
• Half your summer revenue is transient nights → Dockwa.
• Your yard does repairs, sells parts and boats → DockMaster.
• Your accountant wants one ledger, not an export → Proprietio or DockMaster.
• You run a dry stack with a launch queue → DockMaster or Proprietio.
• You are a Nordic or European harbour, or need several languages → Harba or Marina Master.

The shortlist (7 tools)

1. Dockwa

Best at: Marinas that want boaters booking directly. Dockwa lets boaters book your slips online "while you maintain control over availability and approvals," with staff confirming or waitlisting requests from anywhere. Boaters search for slips, fuel and service in its iOS and Android app. Marinas get digital contracts, built-in billing, deposits and auto-pay, a portable POS for fuel and retail, and fuel-dock pump integration. Its Spaces product (formerly Storage) manages wet slips, dry stack and winter storage from a single view, with a live marina map that shows vessel-fit limits.

Not for: A full-service yard that needs a service department today. Dockwa announced its work-order module, Dockwa Service, as "coming soon" in June 2026.

Gotcha: The pages we read cover slips, dry stack and winter storage. Running a mooring field? Ask to see it in a demo.

2. Storable Marine (Molo)

Best at: Marinas, service yards, boat clubs and rental fleets — the four audiences Storable Marine names. Its Slips, Mooring, & Storage service will "assign, renew, and bill accurately by dock, LOA, and season," with online booking, automated contracts, a waitlist and dynamic pricing. The wider platform adds POS checkout, pay-at-pump fuel payments, work orders with parts and technician scheduling, card and ACH payments, and connections to QuickBooks and Xero.

Not for: A marina that wants its accounting inside the same system. Storable Marine connects to QuickBooks and Xero rather than replacing them.

Gotcha: Two names for one product: getmolo.com now redirects to storablemarine.com, where the product is still shown as "Molo." Search for both when you check references.

3. DockMaster

Best at: Full-service operations. DockMaster serves "marinas, boatyards, full-service yards, marine dealerships, and mobile marine technicians." Its modules cover visual slip management with reservations and billing, transient bookings, wait lists and deposits, dry stack and launch scheduling, work orders with estimates and eSignatures, parts inventory with purchase orders and barcodes, a touchscreen POS, boat sales, and full marina accounting (A/R, A/P, general ledger, bank reconciliation, year-end close).

Not for: A mooring-only harbour with no service department. The depth is built for yards that repair, store and sell boats.

Gotcha: DockMaster sells two products — DockMaster Desktop (its marine ERP) and DockMaster Web (cloud CRM, customer portal, eSignatures and payments). Confirm which modules sit where.

4. MARINAGO (Scribble Software)

Best at: Marinas renting many kinds of space. MARINAGO Office is a cloud platform from Scribble Software that offers "slip, mooring and land storage online reservations," a visual map of the property, a 24/7 customer portal, estimates and work orders, and a POS for the store. Its rental-space page covers "slips, moorings, dry storage, boatyards, and more," with recurring billing on monthly, quarterly or custom schedules and pre-season billing for seasonal tenants.

Not for: A marina that wants the ledger inside the marina system: MARINAGO describes "two-way integration with several accounting platforms."

Gotcha: The product also serves campgrounds; ask for a demo set up like your marina.

5. Proprietio

Best at: Slips, moorings and dry stack with the books in the same system. Per Proprietio's marina page, every space carries length, beam and draft limits and the fit check flags a boat that does not fit. Per-foot agreements run annual, seasonal, monthly or transient by the night or week, with deposits. Waitlists run per size class: free a slip and the next boat that fits gets the offer by email. Fuel and ship-store sales go on the boater's account with the right sales tax, shore power is billed from meter readings, dry-stack boaters request launches from their phone, and a hurricane plan tracks who is leaving, hauling out or staying. Everything posts to a double-entry general ledger. Boaters pay and upload their insurance certificate in a portal in English, Spanish or French. Vessel-lien checklists cover Florida, California and Texas (Michigan in review).

Not for: A marina that needs a retail point of sale (inventory, barcodes, cash drawer), a transient-booking marketplace, self-reporting smart pedestals, or a boatyard service department — none are on the marina page. The marina plans are offered in the US.

Gotcha: The lien checklists follow each state's statute as Proprietio reads it; they are not legal advice, so have counsel confirm notices and waiting periods before a sale.

Pricing: Published on the marina page and /pricing; 15-day free trial, no card to start. Slips, boats and agreements import from CSV templates; free migration applies on every annual plan and every plan from Growth up.

6. Harba

Best at: European harbours and their guest boaters. Harba is a Copenhagen software company; "marinas across Europe run on it." HarbaMaster shows a live marina map of which berths are occupied, free and paid, online guest booking with QR-code or in-app payment, a CRM with email and SMS, automated invoicing, a POS, bookkeeping sync and HarbaPower metered shore power.

Not for: Its pages and testimonials center on European harbours, so a US marina should confirm US payment and sales-tax handling in a demo.

Gotcha: Harba speaks of berths and dry stacks; the pages we read do not mention moorings. Ask if you run a mooring field.

7. Marina Master

Best at: Marinas with a shipyard, and operators in several countries. Marina Master (MARINA MASTER Ltd) lists modules for an interactive reservation system, berth contracts with automated extensions, invoicing with a payment link on every invoice, a boatyard and shipyard module, POS and fuel sales, and the myMarina customer portal. It supports more than seven languages.

Not for: A dock that only needs slips and online payment. Marina Master is a suite of modules for marina and shipyard operations, with local partners around the world.

Gotcha: Like Harba, it speaks of berths; moorings are not mentioned on its home page.

Comparison for marinas

What marina software needs that property software does not

• Space dimensions. Every slip, mooring and rack needs length, beam and draft limits, and the system should refuse a boat that does not fit.
• A vessel registry. LOA, beam, draft, registration, lienholder and insurance certificate, with reminders before it lapses.
• Agreements priced per foot. Annual, seasonal, monthly and transient terms, priced by LOA.
• Waitlists by size class. A freed 40-foot slip should go to the next boat that fits, not the next name on a paper list.
• Fuel, store and shore power on one statement. Several revenue lines that must all reach the books.
• Dry-stack launch scheduling. A queue the yard can work in order.
• Storm and lien workflows. A hurricane checklist, and a documented path for unpaid slip fees.

FAQ

What is the difference between slip, mooring and dry-stack management? A slip is a space at a dock, a mooring is a buoy in open water, and a dry stack stores boats on racks and launches them on request. All three need size limits per space; dry stack also needs a launch queue. Ask each vendor to demo the type you run most.

Can one system run the fuel dock too? Dockwa lists pump integration and a fuel-and-retail POS, Storable Marine pay-at-pump payments, and DockMaster and Marina Master a POS. Proprietio charges fuel to the boater's account with the right tax but is not a retail POS; keep your register for walk-in sales.

Do I need a transient booking app? If transient nights matter, yes. Dockwa and Harba run boater apps; MARINAGO and Storable Marine offer online reservations. Proprietio does not connect to a booking marketplace; boaters book with you and you enter the stay.

Which tools handle a full-service boatyard? DockMaster, Storable Marine (Molo), MARINAGO and Marina Master all list work orders or a boatyard module. Dockwa has announced one. Proprietio's marina page does not cover a service department.

Can I switch without retyping every boater? Ask every vendor how they import your data. Proprietio imports slips, boats and slip agreements from CSV templates, and imported agreements create their invoices and ledger entries.
