Sure, I'll work on getting a how-to together with pictures but here's the basics of what I did:

Washed both headlights with Meguiars Gold Class soap
Used normal painters blue tape around the headlights so I didn't hit the rubber seal and create white marks or burn them.
Used 1500 wet/dry sandpaper and used Meguiars Quick Detailer has lubricant. As I mentioned below, anything would work instead - water even. Sand very lightly - it's very easy to sand too much and go through the clearcoat. It should have a hazy look when you are finished. I normally go in a criss cross pattern when I sand.
I used Meguiars Rubbing Compound on an application pad and spread it all over the headlight. (I didn't realize this compound was for hand-use only. I would suggest using compound made for a high-speed buffer)
I used a variable speed Cornwell polisher (couldn't find one online, DeWalt is also a great polisher). I can't remember the exact speed I used, it was about a 3 I think. You want it to be fairly low so you don't burn the paint.
Use a wool buffing pad on your polisher. In my experience, foam will burn your headlights almost 100% of the time. Wool can still burn it, but it's more forgiving.
Buff in a criss cross pattern across the headlights while keeping it as flat as possible and buff until most/all of the buffing compound is off.
Repeat the applying compound/buffing process until you reach a 'good enough' result. Don't expect it to be perfect on a headlight, some scratches just won't come out.
When you're finished, wipe off excess compound.
At this point, you can apply a wax and/or sealer if you want. Due to time only, I didn't do this step.

That's basically the process I went through - I should have used a sealer and I would recommend it, but I didn't have any on me and it was getting late.

I refinished my hull this spring on the advice of another redditor. His uncle is a professional boat detailer and had used this method for years with great results:

Scrub Brush + Water + Soft Scrub w/Bleach
Rinse, rinse again
Wet sand with 2,500 grit wet sanding paper (get it at auto refinishing place). Don't wear a ring(s), keep your palm flat. Do not try to wet sand textured finishes (top side)
Rinse, rinse again
Using a professional buffer like this one, apply Meguiars #105 ultra cut compound to a wool or foam application pad (get 9" pad for 7" polisher) Work on a 2 x 2 ft space at a time, keeping the wheel flat. Run it between 1200 and 1400 rpms.

Your finished result will look like this

If you want to remove decals, pin striping, or the name, remove it first using an 'eraser disc'

It took me a good 6-8 hours, but I was very, very impressed with the results. When I started, my gel coat was getting chalky, and little black spots. I actually enjoyed doing this, and if you're in the Milwaukee area, I'd be glad to help/lend you tools whatever.

Looks like she's got great potential, I'd take her. Rigging, lines, motor... you could set her up for 1-2K I bet.
