A week seems ample for DIY, unless the weather is awful. You could consider getting some tarps and tenting yourself in.
Aim for three coats, allow 24hrs between each coat, and keep going until you run out of time or paint.
You'll need a 6' ladder (or two) to get in and out of the dock, and your gang plank. You'll need wellies to start with, but after 24 hrs it'll be almost dry enough underfoot for carpet slippers !
Buzz over the hull with an angle grinder with wire brush attachment, to get the worst scale and crud off.
Arm yourself with a dozen INDUSTRIAL (quality & size) paint rollers & trays and just throw them away after each use.
While you're there, check, replace or even add more anodes.
Check the prop for dings and remove fishing line etc from the gland. If fitted, check the split pin too.
We did it a couple of years ago in Hatton dock in October - see below :-
