My deck went green in patches over the winter. I found the following way to remove the green.
Using Stabrite Boat Cleaner. fairly strong mix, I got down on my hands and knees and scrubbed across the grain with a sponge, that's right a sponge. When the deck dried the green was gone.

Now all I have to do is find a cure for the spray hood.

I beleive the green comes from being stored under trees in the winter, by the previous owner.

You want to try the none slip deck cleaning powder and a scrubbing brush. I've only got the swim platform to do. But it comes up bette than new.

Last week end I had to paint the outside of my Cottage, front and side no problem but the back was covered in green algae which had to go....

Went down to the local agricultural store to see if they had anything ( as they stock almost everything) The guy behind the counter recomended Domestos, as it contains (I think) Sodium Hypochloride... Other bleaches dont have this apparently.

The point is that it worked so well and so quickly that I didnt have to paint the back in the end, as under the slime was perfect paintwork.

I used, 1 part Dom to 2 part water and applied with a soft broom. Obviously you would have to be rather more cautious but a a quid a ltr its got to be worth trying.

My wheelhouse cover and sailcovers have had exactly same problem. Ive replaced the wheelhouse cover, but will be trying it out on the sailcovers soon.

Keeping the green at bay...

There’s a way of helping to keep this green stuff at bay, Chris, and it involves almost no work. Hallberg Rassy recommend a product called Boracol, which is generally sold as a timber preservative. It’s highly effective in killing green algae, mould spores and termites. Unfortunately, in the UK it’s only licensed for professional use. However, the two active ingredients - disodium octaborate (a fungicide) and benzalkonium chloride (an algaecide) - are available in various amateur products. Easiest to find and use is Polycell 3-in-1 Mould Killer (about £5 a litre from bigger B&Q stores). It’s a colourless liquid. I used it last year on my HR352, and was pleased with the results. The deck was affected minimally by algae over the winter, compared with nearby boats.

To apply it, first clean the deck thoroughly and allow at least 24 hours to dry. Choose a day when rain isn’t expected for 24 hours and apply the liquid liberally with a soft paintbrush. You’ll need about 2 litres for your Najad 37. You should wear protective gloves and safety glasses. Wash splashes off skin immediately. Reapply every 4-5 months.

I use the same liquid on the inside and outside of my sprayhood, again with good results.

I think perhaps the best thing would have been to take the spray-hood off over the winter. I guess that goes for all fabrics.

Re: Keeping the green at bay...

We do what Vickie at HR Parts reccomends and thats to rub the deck lightly across the grain with a scotchpad and some soapy water. Twice a year, with just a wash down other times has been more than enough.

For the sprayhood. I take it off, spray it with Mildew Remover (which is probably mild bleach), then scrub it with washing poweder, then bung it in the washing machine then spray it with Waterproofing agent - once a year. We leave the sprayhood/shed up all year round to protect the cockpit.

Works for us.

But...

But you started off with a nice clean smooth new deck. You should have seen the state of mine!

On teak decks a sponging with sugar soap removes "green" from the deck and cleans it with minimal disturbance to the timber.
