I already said I don't care if you bring a gps..
I also wouldn't mind you bringing whatever toys you want along. But, on my boat at least, I would have an issue with someone using a plb before I decided to use an EPIRB. That's a safety issue. I don't need the coast guard running around looking for a plb, with no information on the boat or how to contact me, instead of following my registered epirb, or maybe getting confused and thinking there are two separate emergencies.
Control of communications stays with me. Period. If you don't like that, go on another boat. Additional emergency equipment isn't a problem.
Also, don't expect to be able to bring ANY personal gear into the raft (same goes for me). It stays on the boat. If you don't like that, you are free to to find another means of flotation.
Seriously though, you are making a big issue out of nothing. Bring the gear, just ask first. At least that way we know it's there. You might not be able to tell anyone when its needed. I've brought my ditch bag onto buddies boats before when they ask, but I always explain whats in it so somebody besides myself knows.
