If you can or maybe dang will see this I'd consider editing the title; I read it as AIs thinking ai and not AIS before I clicked it.

Also, awesome board, if I sailed that'd be a good (and small) backup. Slap gps, a solar cell, batteries, screen, storage for maps, maybe even throw in a wideband transceiver for comms and have an all-in-one backup nav console in box.
