What is on the shelf

Why keep it with the boat

Equipment manuals are where the service intervals, wiring diagrams, fault codes and torque settings live. With the Garmin GSD 25 documents in the vessel's library, the engineer on the dock can read the same page the owner is reading, and the maintenance log can quote the interval the manufacturer actually specifies rather than the one somebody remembers.

Keep Garmin GSD 25 on the boat, not in a browser tab

This manual imports into your vessel's library in one tap and lands in your own Google Drive - so the next time it is wanted it is already aboard, offline, at two in the morning with the signal gone and the engine refusing to start.

  1. Search Garmin GSD 25 in the Library and tap Import.
  2. It is filed under the right category and mirrored to your Drive automatically.
  3. A free account and one boat is all it takes - about a minute, no card.

Get Garmin GSD 25 on my boat

Helmy Free covers one boat with usage limits (three library imports per vessel). Helmy Pro is unlimited for €5 per vessel a month. Got a manual nobody has shared yet? Upload it to your boat and share it to the shelf - that is how this library grew in the first place.
