What is on the boat, where it is and what is running low

Inventory is for things you use up and replace. Equipment is for things that stay installed. Mechanical items are the engines and drives that need hours and service.

The spares locker, listed

Free
  • Inventory with photos and documents

    Impellers, filters, belts, fuses and oil, each with a photo and the manual or datasheet attached.

  • Part numbers and storage location

    Record the part number and which locker the item lives in, so the right filter is found before the engine is opened.

  • Low-stock flags

    Spares that are running out are flagged in the list, so you reorder before the job, not during it.

Engines and drives, with their hours

Free
  • Engine, saildrive and generator records

    One record per unit with make, model, serial and its own hour counter.

  • Add any unit by hand

    Type the make and model of any engine or drive; the maintenance schedule stays yours to set.

  • Tied to the maintenance plan

    Hour-based tasks count down from the unit's counter; a new reading moves every task that depends on it.

The boat itself

Free
  • Specifications on one card

    Type, year, length, draft, build and registration, so they are at hand when someone asks.

  • HIN suggestion and USCG manufacturer directory

    Vessly suggests the hull identification number format and looks up the builder code in the US Coast Guard directory.

  • Up to 3 boats

    Each boat keeps its own inventory, equipment and engines. 3 boats on Free, up to 10 on Pro.
