I'm wondering if there's some way to use RM maps on the apple watch.
What I'm looking for is:

• ability to show/mark waypoints and handle the import/export of them (GPX or USR).
• use in some way ReefMaster depth maps (would they be vectors, passing via the garmin exporting process and maybe by handling them with GPSmapedit, or shaded relief rasters/flat maps with MBTiles or other better formats for the purpose
