Bad paint job

What? The boat is not worth a couple a grand? Must be in really bad shape.

Like CaptRonn says, nothing will stop the peeling off regardless of what you put over it. Your only option on the cheap is to scrape off any obvious peeling, sand and repaint the area.
What should I paint it with? What kind of paint? Primer or no primer?
 
What is underneath the oil based paint? If its fiberglass/gel coat, you could media blast it - which is far easier and safer than sanding or sandblasting. Walnut shells work great, but you will need a really good air compressor (gas powered). Strips everything down to the gelcoat.

The downside - it is a mess to clean up. Stuff gets everywhere, anywhere, and into little nowhere spots. Tape/tarp everything. Safety glasses, respirator, and maybe ski goggles as well.
In some places it is fibreglass, in others gelcoat. I think I will try to find a chemical paint stripper
 
I am not sure that we have that brand in Europe. Paint stripper is a good idea though, I will go to the paint store and ask what they have

Well, paint stripper in general can be nasty stuff especially in confined spaces so be careful.

Avoid methylene chloride strippers.

The Aerogreen stuff is biodegradable and has no harmful fumes.
 
It is really not a phenomenal price. The boat is very small, only 5 metres by 1.5 metres, and the quote only includes the inside
It IS a great price... if we were talking about the boat in your signature. If you are talking about a different boat, you never mentioned that and that probably would have been good information to include. But even so, $2K is still extremely reasonable for that job.
 
From the original first post:
The boat is just a little weekend runaround so that is not an option.

I guess we have to interpret this to mean something other that your 290... you really need to be more specific if you want specific recommendations.

Sure ain't no 290!

Out of curiosity why would you buy such a boat in the first place?
I stewed on this for a while then had to get it out - what gives with the arrogant and condescending comment?
Someone new comes on for help and you throw this down.... To what end is the comment for? It's simply just wrong.

I kind of share your reaction to the comment as well, but at the same time think the comment is valid. The OP has discarded all of the technically sound advice for correcting the problem as "too much"; time, effort, money, etc, prior to sbw1's comment on what she admitted is a new purchase. So it seems reasonable at this point to dig deeper into the motivation for having this boat to tailor some form of alternative remedy.

BTW the boat she is talking about is 5 meter x 1.5 meter, or 16 ft x 4.9 ft, so it is not the 290 listed in her sig. Sounds about the size of a Lund or Alumacraft open tin boat. Around here the clammers and lobstermen frequently paint their tin boats with house paint; its cheap and looks like hell, and as such is a great theft deterrent. Using house type paint is also common in Italy (home of the OP) by professional fisherman as many open fishing boats are wood construction.

That said, with that size boat one could sand and paint the exterior in an afternoon with a good sander and brushes, hardly the whole summer as she stated: "I want to be out on the boat all summer, not sanding it", above.

I re-painted this below, that is a little smaller, over a period of four days with total accumulated time of less than six hours. It took the time because I did bottom paint, hull paint, varnish and bilge paint. Total tools being a Makita rotary sander, paper, and a dozen foam throw away brushes. If it had been one color I could have done it faster. I did use marine paint only because I had it left over.

@sbw1 comment was out of curiosity.... how you guys jump to arrogant and condescending is a stretch at best
