I have recently purchased a small rib, it was sold as a project and possibly made by Narwhal. I have contacted Narwhal and they said it is not made by them.
There is no plate or serial number on the hull.
Can anyone identify what make it is from the picture please?

Is that small blisters that the tops lifting off? Or some kind of impact damage? If it's impact damage like stone chips then I guess you could just fill and send back
If it's blisters with water underneath then it's probably osmosis which is bad news . The proper cure is to strip the gelcoat back to the laminate then re-gel and sand back to a good surface finish.
how big an area is affected
Yep it does look like the results of osmosis... the curse of on the water all year river craft. Most used river craft of any value are subject to surveys when sold and the presence of osmosis blisters can result in a quote of 25%-100% of the craft's value to properly repair.
Less of a problem on a smallcraft that's out of the water when not in use though. If you aren't that worried about the cosmetics it would go on ages using as-is. If it's a restoration job then you need to dry it out for as long as possible and refinish. For a small area gel coat filler would probably be fine... if it's the whole hull then it will need a bit more of a pro finish.

Hi Beamishken,
It looks like stone chips, but all over the hull. The hull is dry and the marks are on the surface of the gelcoat and no deeper.
Best way to resolve this is to re-gelcoat I guess.
not an expert on this jame but gelcoat dosnt cure in air thats why they use flowcoat for surface stuff which has wax added someone will be along who knows but you could speak to east coast resin supplies who are very good at helping you out in the mean time
plus there are some paints they use but not familiar with which
cheers jeff
to work with gelcoat is a difficult stuff because of its curing and finishing process.
interlux has an awesome product for to repair the osmosis problems.
checkout interlux gelshield 200, it is an quickdrying epoxy easty to use and apply
i am satisfied with the color match of it to the original gelcoat on rib.
i suggest you to wash the repair area wish dishwash soap, apply gelshield plus primer before gelshield 200 and apply 3 coats of gelshield 200.
you will be suprised about the result mate

Thanks for that, its the whole hull that has marks like that over it. I am restoring it anyway so will look into gelshield.
That looks to me like the Gel has been laid in the wrong environment. too damp which causes blistering. if its all over the hull then that's my prognosis on the beast. Osmosis is rare to completely cover it unless its been sunk and the pitting is very uniform not in patches and little staining either.
Just re gel the hull

I think you are right. There is a dirty mark across the transom that looks like it may have been in the water a while at some point.
