Hi Charlie,Thanks for that,they are very minor scratches not through gel coat by any means only minor cosmetic and one right underneath front of ride plate where previous owner has used some general black paint not sinister,thought of using some Hamerite black smooth on this area as no one will ever see only me and use very fine compound and wet and dry on rest what do you think. Confused

Wouldnt use hammerite on the hull. If the scratches are not deep and only in the gel coat then flat them extremely carefully with a light grade wet and dry and plenty of water....

Yeh no problem I have a bit of an OCD thing going on ! I have a whole load of different grade polishes pads and Rotary polishing machinery. I even have digital measuring device that measures the thickness of the paint on the panel I'm working on so I don't burn through the lacquer... Different colours show swirls more than others. Blacks and dark blues being the worst !! It helps to know what car We are talking about as manufacturers paints can vary IE BMW paint is very hard and needs a fairly hard pad and a more aggressive polish . Nissan Paint is very soft so a soft pad and low cut polish combination works best and is safest...
Fantastic results can be achieved with the right kit !!

Without seeing the pics its difficult to say but if they are in the gel they will polish out.. Its possible to layer the scratch with a lacquer brush then flat carefully with really fine grade wet and dry 3500 grit or so. then polish and do again if necessary with time most scratches even if through the gel or lacquer can be made virtually invisible..Cool

stokey - its a very common problem, hving scratshes and trailer/ beach damage to the underside of the hull. If the damage is purely gelcoat damage, you can normally sand it with wet and dry paper. Use lots of soapy water in a spray applicator bottle. you start with a medium paper and work up to very fine, normally 1500 or 2000 grit. you can then polish the sading with a compound paste such as G3 which wil restore the normal shine. The process from strating paper grit to finish will depend on the depth of the scratches.
 
The problem you may encounter is that Yam's have a very thin gelcoat from the factory, and its hard to blend repairs by adding new gelcoat (surface coat), if its black, game on, if its white it will take a little more work.
 
If you go down a painting route, you should only use an air drying 2k paint, nothing else will adhere properly and may even reat with the gelcoat.

Surely You would start with a high number low abrasion wet and dry first to see if that shifts them ?? This way will remove less or only as much gel or lacquer as required ?? I would always use the least abrasive W&D that's needed its far safer and less likely to strike through either the gel or lacquer.

You can always move to a 2000 grit if needed but if its not and You strike through Your f┬úcked ! Especially if You on a Cars paintwork 

Light grade W&D might take a little longer but it shifts the lacquer or gel far slower and is massively safer as a result.. Especially if the gel-coat is thin

Detailing spray (Google it ) Is a far better lubricant for the W&D.....
