Emerald Posted June 19, 2012 Report Share Posted June 19, 2012 Hi all, just looking for advice whether I should go to the expense of hull blacking this year or not? The money tree is looking decidedly withered at the moment so I am looking like most people to save cash where I can. That said I want to give the boat the best possible care I can so is it false economy to scrimp on her this year? I estimate the boat may have been in the water for approximately 15 months from new and I believe the existing blacking may be INTERTUF 16? BTW The swans are doing a great job on the clingy green stuff stuck to the hull :0 Link to comment Share on other sites More sharing options...

RLWP Posted June 19, 2012 Report Share Posted June 19, 2012 Can I check my understanding? The boat is around fifteen months old? If that is the case, I wouldn't worry. We try for two years, and have occasionally left Tawny Owl for three. Tawny is much older than your boat Richard Link to comment Share on other sites More sharing options...

If so and the original blacking if intertuf or any blacking commercially available then I don't see why you should be looking to redo it. Let the money tree recoup a bit and think again next year or even. The year after that. Link to comment Share on other sites More sharing options...

Richard That is correct we have had the new boat at Christmas but I think it has been in the water for around 10 months before we bought it.

BTW The swans are doing a great job on the clingy green stuff stuck to the hull :0 I recently took our boat out for blacking, and was surprised at how tough the underlying Comastic layer was still intact... I dont think it really needed the additional blacking but that is because it had loads put on in the past most likely. I'm in the process of buying a new widebeam, and I had a good look at the blacking coating which comes on a new boat, and I dont think it's as good as a boat thats been blacked routinely for many years. So if your boat has only been in the water for 15months, it probably has quite a thin coating of protection....and the sooner you put some extra protection the better....however...I also dont think that waiting another year would cause THAT much of extra corrosion if you havent got the cash....and...I would guess that boats that are nearer salt water/rivers..may be more at risk than others...but I'm not sure if thats true or not. I do know there are different kinds of anodes available. Interestingly, when you see how an anode corrodes, it makes you really think about what's actually in the water.

Emerald Posted July 5, 2012 Author Report Share Posted July 5, 2012 Sorry for bringing this up again but how do I know how much blacking I need for a 57 footer? Link to comment Share on other sites More sharing options...
Jamesb4uk Posted July 6, 2012 Report Share Posted July 6, 2012 If it helps i used 15 litres (Rylards) on a 42 footer. 2 coats on the base & 3 along the waterline. Link to comment Share on other sites More sharing options...

It very much depends on who built the boat and who blacked it. I took my Liverpool boat out of the water after 1 year because I was warned, and as predicted the blacking just fell off as soon as the pressure washer hit it. If it's a budget boat then I'd get it out when you can, but as Deano says, waiting another year won't make much difference. 3 years after blacking my boat, when I could clearly see rust patches on the waterline, I waited another year. The following year when I eventually got the boat out of the water those rust patches were wire brushed off and the steel was fine. It was just superficial surface rust. One caveat to that is that if your boat is left for long periods on shore power it's galvanically isolated. Link to comment Share on other sites More sharing options...

I don't have a galvanic isolator but I will soon. The damage from not having it looks like someone opened up an AK47 and took pot shots at the hull. Anodes only work in the area they are fitted. It was like a band of no pitting up either side of the anode. I had 12 pits on one side and about 32 on the other, the side that the cables run through. The worst thing was lifting two dogs up and down a 12" drop. Nasty. Especially after being walked along a muddy tow path Link to comment Share on other sites More sharing options...

Christianonthecut Posted July 9, 2012 Report Share Posted July 9, 2012 Little dogs generally can't. Our cocker spaniel is useless at getting on and off the boat. Link to comment Share on other sites More sharing options...

A lot of new boats are not well prepared or blacked, and actually need blacking more often than an older boat. This is especially true if the millscale was not removed from the steel.

Guest Posted July 13, 2012 Report Share Posted July 13, 2012 hi guys as you may see we are soon to be newbees to the canal system & are trying to understand as much about narrow boats as we can beforehand. Now this may seem a very silly question to all you well seasond folk but 'taking a risk at being ridiculd' What is 'blacking for?' we have been around sea going boats for years & know about antifoul, is blacking similar, please dont laugh, well not too loud. thanks Link to comment Share on other sites More sharing options...

bottle Posted July 14, 2012 Report Share Posted July 14, 2012 'Blacking' is to stop the hull rusting away, there many different types (and cost) but they are mostly of a bitumen type base. The recommendation is to have it done every two years but there is one product that is supposed to last longer. Link to comment Share on other sites More sharing options...
