I have done two things with boats of that size.
1. get it under a large tree and use a chain hoist.
2. Tie the stern off to a large tree and pull the trailer out from under the boat. If blocked as it comes off it is not really that hard to winch the trailer back under the boat. Same as the ramp but reversed.
For the actual cleaning, I agree with a pressure washer but there will be left over stuff that will take elbow grease no matter what.

With that small a boat it should be easy to tip it over a ways to get at all of it. I once took an O'day 20 off a trailer in my parents backyard and using an old block and tackle ( steel blocks and 3/4" manila rope) and a small pickup with one block tied to a telephone pole we tipped the boat almost 90 degrees to paint the bottom and the centreboard before launch. When one side was done we righted the boat and winched it over the other way to do the other side. Afterwards we winched it back onto the trailer. And no spots were missed unlike a boat on jackstands. Even inside the centreboard trunk. And a West Wight Potter is a lighter boat. I'd also caution against the pressure washer.

Almost every fiberglass keelboat that comes out on a marina travel llift for maintenance or storage gets a once over with a pressure washer while it is still in the slings. If you use common sense, start slow/gentle and don't direct the stream at any hull-deck or centerboard trunk joints you're not going to have any problems with a pressure washer.

I've got a 1200 psi PW that would work on that one, as mentioned, use a wide spray head, stay away until you figure out how close you can get before damaging etc.

Along with putting it back in the water to soften it up should work too.

A 4" plastic disposable dry-wall knife works if it is wet, and is safe for the paint.

It is easier to hold on to if you mount it to a 2' length of broom stick.

I use this in the water, where a power washer won't go.
