blackrose Posted January 30, 2020 Report Share Posted January 30, 2020 Why does my boat have a layer of green algae or moss all over it when none of the other boats nearby are growing it? It's also on the new paintwork that I applied last summer so it can't be anything to do with old paint being a better (or worse) growth substrate. It's true I never clean my boat, I just don't have time, but I never see anyone else cleaning their's either. Not sure if you can see it in this photo. Anyway I gotta get the pressure washer out this weekend. Link to comment Share on other sites More sharing options...

Dr Bob Posted January 30, 2020 Report Share Posted January 30, 2020 (edited) 'Cause its a widebeam. There is a lot more area for the spores to land and take hold. . . . . . eta, they keep landing on my head too.

OldGoat Posted January 30, 2020 Report Share Posted January 30, 2020 I don't really know - but mine has a similar colour scheme - cream on the roof and blue mostly elsewhere. The boat in front of you also has a cream roof (sort of) and it has the same affliction, though to a lesser extent. Could it be due to something to do with light absorption - creating more suitable environment for the algae? Otherwise I don't have a clue...

Tumshie Posted January 30, 2020 Report Share Posted January 30, 2020 It might depend what they all wash their boats with. l've noticed when washing with different products (one in one place then run out and wash the rest with something else) that the green cames back quicker with one wash but not the other; that was with a plastic boat but the green was all the same stuff. The Co-oP used to do a floor wipe cloth that was brilliant, after I first noticed this I did a little experiment where I cleaned a very specific patch with a Co-oP floor wipe and then left it, the patch I cleaned with the wipe stayed not-green for much longer than the area that was cleaned at the same time but with something else - can't remember what the something else was now. I know, I know you can't clean your whole boat with floor wipes but I just thought it was interesting; they're very good for nooks and bits though.

It will get its yearly wash in march or april and will come off. Link to comment Share on other sites More sharing options...

Good point. When we were caravanning I used to finish off the wash with a rinse aid called ‘Bobby Dazzler’ from Fenwicks. It would keep the green (and black streaks) away for 6 months. https://www.ebay.co.uk%2Fulk%2Fitm%2F283019776095 5 minutes ago, mrsmelly said: Ours is like that at the moment, its a bit odd as it wasnt like it last winter and we are moored in the same place.

Its certainly the wettest I can recall in 31 living aboard. It is also one of the mildest I can recall and I was thinking that the mild and wet will have done this??

Tumshie Posted January 30, 2020 Report Share Posted January 30, 2020 Has it also been quite a warm winter down in Englandshire? We've had some exceptionally warm days, reaching temps of about 14C several days in a row at one point. Link to comment Share on other sites More sharing options...

I'm slowly repainting and changing the decks from cream to grey. Roof to be done this summer. Link to comment Share on other sites More sharing options...

Ray T Posted January 30, 2020 Report Share Posted January 30, 2020 Leave it a few years you could get it to look like this! Photo take in 2007 To be fair the then owner was quite ill at the time and wasn't able to clean it. Link to comment Share on other sites More sharing options...
nebulae Posted January 30, 2020 Report Share Posted January 30, 2020 We have a big problem with moss and green algae covering our farmyard. It is tarmacked and cost a lot of money and the moss actualy eats the tarmac. I happened to come across a You Tube video posted by an Irish lady. She sprinkled Biological washing powder across the moss. Nothing to lose,I sprinkled Lidle Bio washing powder over the affected areas. Worked a treat. Moss has not come back yet. Might work on a boat. Jumbo box cost a fiver. Link to comment Share on other sites More sharing options...

Rambling Boater Posted January 30, 2020 Report Share Posted January 30, 2020 Patio Magic worked a treat on our cratch cover. It killed off the algae and seems to have protected it from more growing. I doubt its very environmentally friendly though, if it was it probably wouldn't work so well! Link to comment Share on other sites More sharing options...
