A Question about Antifoul

I know there have been several threads already about antifoul,
my question is this......
I f you purchase a three year old Rib that was antifouled in it's first year , what exactly are the implications ?
I know it may take a little off your top speed. I know it may crack or craze and look cosmetically ugly and I know some people will be suspicious that you are trying to hide something underneath ,when you come to sell it.
Are there any other drawbacks ?

Thanks in Advance for any tips....

One pain in the behind is that you have to continue anti-fouling it annually or even bi-annually.

Charles , Why exactly do you have to continue ?
What happens if you don't ?
Can the existing antifoul be removed without inflicting any further damage to the gel coat ?
Please excuse my ignorance.

Good Question

Good question Bern, what does happen if you dont keep antifouling the hull, i'll assume the boat was left in the water and now lives on land between dunkings before you owned it.
I do know antifoul is a bugger to get off and can hide up a multitude of sins when selling boats.

I have used International "inter strip" on gel coat without any damage. easily gets the antifouling off.

Well simply put, you have to maintain the anti-foul otherwise what's the point. Normal wear and rear will erode it, thus making it imperative to keep re-applying. If you were to keep it out of the water, I would remove it pronto.

Hi Folks

On the subject of antifouling I will keep mine aflote 365 days so need do it.

However I was going to do the outdrive (non copper of course ) but looking at most boats, many dont look like they have had any antifouling on them.

Do people do their outdrives and also is it worth it as you wont be able to do all if it given the inside bits, etc without stripping it down and I dont want to do that.

Regards Gary

Anti Fouling

Good Morning Everyone,

I have anti foul on My Boat - Self Erroding. As the boat will no longer be kept in the water for long periods. I am thinking about removing it completley. Starting to look unsightly crazing and errosion marks on bottom and sides of hull.

I am informed that by removing, this should add a couple of knots to overall top speed. You can get a Gel which acts like a paint stripper and has no effect on Gel Coat, Once hull has been washed and polished should be good as new.

I have read that some yachts are now using a copper based film to lay over hull(sticks on in square pads). It is guaranteed to last over 5 years with no ill effects. Based on cost(2500) for one treatment, over 5 years was very competative against annual treatment for 10m Yacht.

I am not sure if this treatment would be suitable for Ribs but as hulls are GRP on both would this be a problem?

Regards

Be wary

of antifouls strippers

suggest you do a test area well out of view to see what it can actually do

You may find gel is slightly discoloured when removed

I've found in the past it sometimes needs several applications to remove

Far easier than removing it is to repaint it , it is a horrible job scraping it off with the gel remover , not at all easy , highly poisonous , hazardous to your health

Antifoul painted on with a roller can look very good and is quite easy to do

need to wear goggles, gloves , overall & breathing mask

this is a job well worth paying someone to do
