The short version

  • Each has a real cost: MarinaOffice pricing is not published and the product is modular, so the quoted total depends on which add-ons you take and two marinas of the same size can be quoted very differently.; Sea Machines requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase
  • They diverge on capability: MarinaOffice covers Visual marina, Sea Machines covers Autonomous control.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

MarinaOffice

  • Pricing is not published and the product is modular, so the quoted total depends on which add-ons you take and two marinas of the same size can be quoted very differently.
  • It is a Windows .NET application at heart, so remote and mobile use is weaker than browser-native competitors and staff working on the docks are less well served.
  • The same vendor sells MARINAGO as its cloud product, which raises a real question about how much future development the desktop line receives.
  • Running it on your own servers means you own SQL Server licensing, backups and patching, which is an infrastructure cost and risk that never appears in the software quote.
  • Presence is concentrated in North America, so operators elsewhere face weaker support hours, local payment options and fuel and tax handling.

Sea Machines

  • Requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase
  • Targeted at vessels from 10 to 300 ft, so it does not address the largest commercial tonnage
  • Pricing is not published and is arranged directly with the vendor
  • The SM300-NG is the class-approved unit, so the cheaper SM300-SP does not carry the same approval
