Last year previous owner epoxy primed and put on one coat of International Cruiser Uno, which is fine and I was just going to put another coat on because it's meant to be a one season treatment. Do you think I could successfully change the colour from red to blue without scraping all the old stuff off?
 
Slap it on. When the red starts to show it's time for another coat (couple of years?)

(I agree, red looks like red-lead paint. I did someone's boat for them twice in that colour and he liked it. I tried to sway him, but he wanted it red.)

Absolutely no need to scrape the red off.

Quite agree, particularly if you use the same make & then no chance of incompatibility. If you are concerned about incompatibility just use a coat of antifoul primer first. An added advantage is that you will be able to see if the new coat has eroded as the red would show through.

Ironically I am about to do the same but the other way as the maker of the antiufoul I used has discontinued blue and now only has red or black & I don't fancy the latter although I don't know why as you can't see it anyway once the boat is launched.

red just doesn't do it for me (I did the topsides as well)

Well, it might be a bit of OCD, but I take offence to even a bit of slime on my boat's bottom, heeling over and showing a patchwork red/blue would be 'orrible in my book!
 
You can but if you are doing this for appearances sake then it may be counterproductive as there are bound to be times when some of the old staff shows through.

Only a possible issue in year one depending on the erosion, after that once it starts to build up a bit it will be perfect. I am going from red to navy this year and sticking with Uno so will see firsthand what happens.

Fair enough - but from my experience you will get bits coming off that are layers thick, even several years after, and this wioll reveal the old colour

Yes, I went from red to black this year one coat no problem.
 
I agree. I can't stand seeing another boat with anything other than pristine anti-foulingbut then, I can't see the bottom of my own boat when she's heeling so I'm of the slap the new colour over the old brigade. However, as the OP is thinking of changing the colour, I assume the appearances of "his" bottom is important to him (otherwise why voluntarily change) so there's no alternative to scraping back to the gel coat, prepping, priming and then anti-fouling. Done properly he'll be impressed with how little fouling he suffers (but mainly because he won't get back into the water until June, and the season will be half over).

Must say, I couldn't care less about the underwater colour. The a/f that I use, is red when it goes on, but after being in the sea for a week or two, it turns green. (High copper content).
 
Don't worry about it at all. I went from red to navy years ago and changed to cruiser uno without knowing what was there previously. It has never been a problem. If I did get a small patch that flaked them I rubbed it down, re primed it and slapped a couple of coats over the patch. I knew a bloke once in bursledon, river hamble, who mixed several different colours and types together to get a coat on his old gaffer. He was happy so don't get strung out with OCD over it. I'd be more concerned with the moisture content of the hull than whether I had used a different type of anti foul.

After all it's the sailing that's important.
 
Sod the antifouling...assuming that's one of Lakey's lakes that's just a waste of a nice boat!!
 
I actually agree.

However the feeling is that it is a cheap way of having a floating cottage in the lakes, and he also races in the cruising club races. So. Horses for courses.

Huge number of these boats up here.

The 51 ft Hanse was a boat too far.

Well my poor little boat spends most of its sailing time showing a fair bit of a/f due to brutal skipper racing and a tender boat.
However I also find that a/f is a movable feast . What looks nice now is blotchy in a few months till almost gone by the end of the season then it sits at home all winter showing a very blotchy bottom to the public until just before relaunch. olewill
 
Lakey that's ridiculous. OK I kinda get the floating cottage thing but it just seems such a complete waste! Think where you could go on that Hanse...anywhere on the planet, in comfort and at speed, and it's stuck on a piddly little pond. I sometimes get bored with the Solent...which has about as many nice weekendable destinations in a small space as it's possible to get in the UK...imagine Windermere in a boat that does double figures speed with ease!

I once heard a rumour that some boats have to have their keels shortened to be able to sail on Windermere. I had a feeling this was BS...what's the story?
