I found the hoses that roll up flat to be a nuisance. Even if you just
needed 6 feet to hose out a bucket you had to unroll the whole 75 feet
and roll it back up.

I agree, it's a pain to have to unroll it for trivial stuff. But if you
don't know how much length you'll need flat hoses are a much better use of
storage space. I have a 50' regular hose that stays on the dock at our
marina and carry a 50' flat one for travel. If we're away from our marina
and all I need to do is full a bucket it's trivial to just walk to the
pedestal and fill it there. Or use the shower hose on the swim platform.
I've found it's a good idea to put brass shut-off fittings on the hose ends.
At the dock it keeps gunk from getting into the line should someone
accidentally drop it into the water. That and having at the boat-side end
of the hose gives you an extra shut-off should you have forgotten to turn it
off at the pedestal. Just DON'T get a plastic one, they're notorious for
splitting. I had two of them crap out here at home.

An angled one is really handy, like this one:

(I just found that site using google, I bought mine at a hardware store)

If you're sticking something else in-line with the hose at the boat it may
make for a tighter fit in the locker. The angled connector helps keep the
hose from being bent into too tight a curve. YMMV of course.
