I test gear for weeks or months in real conditions aboard Aruna, not on a bench, and document what works and what doesn't. I don't publish anything I can't stand behind.
Start with Reviews for hands on testing of marine electronics and gear, or Projects for full builds and system work on Aruna. I also write about Internet connectivity and staying online from anywhere on the water.
If something on your own boat has you stuck, electrical gremlins, networking, anything boat tech related, I offer consulting too.
