I googled this question and got a million hits. Nothing on the first 3 pages was right. It seemed fruitless.
Ideally, I'd like
a cigarette-lighter adapter
(ie., plugs into any of the boat's cigarette-lighter sockets)
with a power cord extending out from it
(preferably straight and not coiled)
and a fuse in the adapter (ie., plug part).
Anybody know a store that might carry this?
