Changing colour of ant-foul.

Looks to me more like he has set the boat up to be powered up in the lulls, and the trimmer is just dumping a bit of excess power. She's racing...the boat is fairly well heeled but the helm neutral...any more power and she's going to be heeled excessively and dragging the rudder sideways through the water...looks OK to me!

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?

The Hanse is the shoal keel version. However when she was put on the lake (and that was an astonishing drama. The story was on the Hanse web site for some time http://www.hanseyachts.co.uk/readnews.asp?article=15 ) the Wardens had to reposition quite a few shoal buoys (and there are a lot on the lake) to cover themselves. I noticed a passage between Lady Holme and Hen Holme had been closed off. I asked the warden if the rocks were growing and he told me that was the reason. The boat was put on as a Corporate Charter vehicle. I don't think it went terribly well.

I would be more concerned that his main is backing and so not set correctly!!

Yes they were racing and as the gusting and wind shifts are so sudden on the lake you can often find yourself with empty sails. That is taken at one of the worst spots for getting backed between Miller Ground and Calgarth Hall.

I change my colour every year so I get a feel for how much is ablating off. Always using the same make and type.

I have noted though when the time comes for the pressure wash the blue comes off almost completely where as the other colours hang on more.

"On the lake"? Not at sea then??

Re changing colours of anti foul has anyone tried white on a yacht I'm curious about its durability??

 

[skipper681]

I went from blue two seasons ago to red last season, it's still sticking.

No. That's why I said "on the lake"

 

[Boathook]

I changed from white to red many years ago. White sometimes came through in the early days but not now. More to the point when sailing I can't see it and no one has complained to me - yet!

Had white on my hunter delta lift keel for years. This way I could see the dirt and brush off. It always look discoloured ,so changed to dark blue or black.

I used white initially on my little (white hulled) boat. It avoided the problem of actual waterline location and perfection of the waterline. Main problem was that it was difficult to tell what was a/f paint and what was gel coat when sanding the a/f down for new coat. I think I got a bit of build up. With blue a/f not a problem but now after 30 years of a/f ing and 25 years after giving up on white I think there is still some white lurking in places. I have always used a combination of scrub in water and scrub when on the trailer with wet and dry sandpaper (and never put too much on) so have not had to strip build up of old a/f. good luck olewill

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.)

Exactly as I've done for the last 14 years - 2 coats alternately of black or red and repaint when the previous colour starts showing through.

Darker colours (ie black and red) have more of the active ingredient and are far better, in most environments, at reducing fouling. White is worst.

I was told a similar thing by a boatyard; black or dark colours are better because they hold more of the actual ingredient, whereas to get white they have to put in loads of 'whitener'. Not sure if this is true or a sailing urban myth. However, I like black because you can't see the slime so much later in the season!

On fresh water especially dark colours are better as they don't bounce the light around as much. Under the hull with black antifoul it is very dark. The slime grows more verdantly around the waterline where the light is brighter.
