I bought an ARC GlobalFix Pro with the SeaShelter mounting bracket (the kind that auto-releases if the boat sinks). It's designed to mount to a vertical part of the hull... aside from not having much of a good spot, I don't relish the idea of screwing into the hull. Surely, some of you must own this same EPIRB. Where did you mount it? I'm thinking of rigging up a rail mount.
