Equipment manuals are where the service intervals, wiring diagrams, fault codes and torque settings live. With the JL Audio AP300/1, AP300/4, AP600/6 Amplifiers 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.
Every manual here can be imported into your vessel's library in one tap, and it lands in your own Google Drive - so it is there offline, on the boat, when the engine will not start and the signal has gone.
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.
