Wiring Question

Iím going to install a 12v TV/DVD and rewire my stereo this week on my 95 Catalina 30; wiring both to a circuit direct to the battery so I donít have to rescan stations every time I get on the boat (boat is kept in a marina other than occasional overnights at anchor).

The stereo (Sony car stereo) is pre-wired with a fused line to run to the battery directly (P.O. didn't connect when he installed the stereo). I looked at the specs on the 110v adapter for the TV. Its output is 12vdc/5amps. So the plan is to add a 12vdc plug for the TV in an outlet box on the forward bulkhead, with a 5amp breaker in the box so the outlet will be switched. Then run a line from the outlet box to the battery with a Anchor 5amp slow blow inline fuse where it connects to the battery post.

Why create a switched 12v outlet rather hardwire it? I want the option of switching it off if Iím trying to conserve power or troubleshoot a problem; and the outlet gives me a place to plug in the extension cord for a spotlight at night.

My question is am I missing anything from a safety perspective? I want to breaker to trip before blowing the fuse. Is there any reason NOT to use a slow blow marine fuse in this application?
