Before selling her, I would like to polish the hull of our Karnic 2660 sport fisher,

the boat is 13yo, alway's stored on a trailer,
she has never been polished, just washed with water, occasionally with soap
Except from some small scratches from wear or tear, the hull is in fairly good condition,

The boat spend most of her live under a shed, but 3 seasons ago, she was all summer on the trailer parked in the marina in open air,
since then, one side is a bit faded by the sun.

I intend to polish / cut the hull with standard polishing paste,
is this a good idea ? what grade should I use ?

Thanks for advice !

Im very keen on the new 3M stuff in the purple bottle. With a lambs wool thing in a rotary polisher. Try medium and if it doesn’t work go heavy.

How much are you selling her for and where is she?
 
Every time you polish a hull the paint gets just that bit thinner. Before you polish, give this colour restorer a try. It’s like a miracle solution. Brings a blue hull up a treat and lasts for 6-8 months.

Hi is the boat painted or is it Gelcoat?
If Gelcoat the fading is going to be partly oxidation, for that I would recommend 1500 grit wet and dry used wet and gently by hand with a stiff ish sponge block, that will remove the oxidation much faster than polishing compound alone. (don’t push hard tho you’ll clog the paper and scratch it). Remember to hose off and rinse regularly, keeping the wet n dry clean. Then if you want best results go over again with 2000 grit to really smooth it out before wash and rinsing again, then using the fine polishing compound with a rotary buffer, that procedure gets excellent results for me.
I'm approaching 60 and can cover my Princess 30 DS in about a day and a half with that process. I also apply a finishing wax with UV protection which reall brings on a shine and protects against the oxidation.
If it’s paint then it really depends on the type of paint and remaining thickness, a similar process will get good results, but you need to be careful not to go through the paint. Some paints will react to the the polishing compound, so try a small area out of sight first if you can.

I can also give the 3M stuff good notes (in the way as Ellesar commented: light -medium- heavy). 3M Fast Cut is also a good compound IMHO. Rubbing Compound from TOTAL BOAT should also work well, but I never used it. I think the blue hull is gel coated and not painted???
If gelcoat you can remove the small scratches with a 800, than 1000 or 2000 grit sand paper, than polishing. I have very good results with this procedure and the gel is as new after nearly 10 years. Rotating polisher with lamb wool... First lower RPM with light pressure, than more RPM with lower pressure...The gel should get too warm!!!
 
Gary Jeffery posted at the same time, sorry the comment was not online when I replied my post. Its nearly the same message...

On car paintwork rubbing bar soap (ie: solid rather than liquid) on the paper avoids clogging and gives a finer finish. This may translate to gel coat.

thanks !

I'm not sure at what price yet,

its a twin engine VP D3-190 = very powerfull for the size !! (was not standard available)
I have full service history (one owner from new)
and it has many special options and add ons,
sa the Atlantic radar arch, radar plotter, etc..

she 's curently in Belgium, so not sure if I can sell here in UK, with customs clearance and vat and all that,
UK market is much bigger then in B, could try holland,

its hard to find this model on the used market,
the ones I found where approx 35..37000 euro,
but that is with petrol or 130Hp diesel while mine has far better specs,
and a aluminium Harbeck trailer
so I was thinking at a asking price of 45...49000 euro, including the trailer,
or would that be too optimistic ?

boat is used for family holiday, watersports day boat, and nothsea diving
we trailered her to Schotland, Cornwall, Croatia and sof,
its a very multi purpose boat !
see cruise reports in the sticky post on top.

Are those mudguards set too low?

not really,
the mudguard is fairly low,
the boat has gained weight over the years ;-)
and she is tilted a bit too high with the nose (?)wheel,
when the hook is attached to my car, the trailer is perfectly horizontal,
and with the tires at full pressure (4bar) she's is really ok,
the wheels have never touched the mudguard
 
Looking at the fading on the hull Bart, i would give it a first pass withe 3m fast cut, then a 2nd with 3m finesse it and then a coat of a good hard carnauba wax. It will look so good you won't want to sell it :)

I've alway's loved that boat, even without any polish ;)
thats why we kept her so long,
but the last few years we used her so little that hopefully someone else will apreciate her sharms :)

Yes you have loved that boat Bart, and we have enjoyed the many stories you have posted from your cruises, a truely versatile boat that has had a lot of love and attention.

The market is quite buoyant and these good quality boats will sell quickly. Give her a good detail/clean up and get her on the market for the spring buying frenzy.
Perhaps an astute YBW forum member will be lucky enough to secure her before she hits the open market?!

Totally agree with the carnuba wax. Slippery as a slippy eel. Simonize 6quid eBay

Thanks C, how are you by the way, long time no see :)

Our Karnic is indeed a very versitile boat, but i think that the brits look a bit differently to boating in that respect,
much less trailer boating, and not adventureous / crazy enough to tow a +3500 Kg rig through the country, let alone through europe :cool:
but anyway the boat might hopefully find a new enthousiastic (and young :);) ) owner.
