Careful ! - will send you a PM

At most you'd use half a litre of oxalic acid or proprietary hull cleaner on the hull. I might do the yellowing stains near the waterline once a year. A half-litre of the hull cleaner will dilute into the millions of litres of lake water. I'm sure the effect on the environment is akin to copper antifoul leaching into the water.

As for engine issues and not being able to move the yacht, you could mount an outboard bracket on the stern temporarily, and when the diesel does work, then fill in the 4 holes you drilled. Not ideal to have a motor so far back, but better than not being able to manoeuvre the yacht. It's what I did.

You could always sail it off the mooring and sail back on. Just pick the weather day to suit. Great practice.

Thanks everyone. I actually used a small amount of boat wash, vinegar and water and elbow grease with a green pad and it helped clean up the cockpit and stern. It was a bit windy on Sunday, so I wasn't comfortable spraying acid anywhere. Still stained, which I will try a little oxalic acid on it but I actually didn't mind sitting down in the cockpit after that. I should have taken before and after photos. Still have the cabin top and bow if the boat so I still can. But had to deal with so many feathers, sticks and bird poop.

I'll hold off sailing it off the mooring at the moment. The standing rigging was last done in 2011, according to receipts I found on board.so unsure if the condition. I was trying to clean the rigging so I could exam and see if there broken strands anywhere.


But I did find heaps of paperwork An original Bukh owners manual, bukh service manual, manuals for all the electronics, receipts dating back to the 90's which told me my engine is not the original Bukh but was replaced with a reconditioned DV20. The engine was last serviced in 2021, according to paperwork but had issues shortly after and has been a bit neglected.

I did think of putting a temporary engine in the back in the meantime, I'll see how I go with the Bukh over the next few weekends.

Trek, Bunnings has it.

Im getting one today :-) .... except its IP67 - splash proof - not sure if the motor end would be ok under water

Lemon juice for waterline stains on the gelcoat, buy from colesworthaldi etc
Sponge on rinse with saltwater after 20-30 mins. Also great for removing small rust stains but as with any acidic cleaners it does strip the wax out of Gelcoat.

That's brilliant Jethro, gadget of the year, definitely! I'm going to get one too.

Trek, Ip67 is supposed to be good to 1 meter for up to 30 mins. I guess if you wanted to do a deep rudder, maybe a plasic bag over the head somehow might mitigate the water pressure ingress to some degree? What do you think? I'd use it primarily for decks and hull sides to or just below water line I think.

It wouldn't need to last many cleans to be cheaper than a diver....
