Do I need to use a different antifouling for use in fresh water ??? I've always been a salty sailor and used Blakes or International concoctions to get rid of barnacles and such...
I've seen boats taken out of Lough Neagh over here in Ireland and they are badly coated in a long weed so I would recommend consultation with local boatsmen re anti-fouling rather than take the chance.
Steel Narrowboat - black bitchimen paint to protect the steel - natural anti-fouling flowing all around you in the cut, BWB call it water(but not as we know it Jim). Waterline will need the occasional brush off. 5 years without
Use "Waterways" antifouling...and don\'t forget to change your anodes.
I have a steel-hulled boat that lives on the freshwater River Trent most of the year.
We use International "waterways" product that seems to work as expected. It is the standard product in any inland waterways chandlery. (I'm sure the Blakes version will be just as good)
Just a little reminder though...if your boat is usually fitted with zinc anondes for the salty stuff, these will need to be swapped for magnesium ones prior to a long period in freshwater.
As I understand it, the zinc ones are not sufficiently dissimilar to the valuable bits on your boat for them to do their job in the less-electrolytic fresh water. Conversely, magnesium ones will disappear very quickly if exposed to salt water.
