Deep Joy is moored in Swansea Marina, which, as far as I know, is freshwater. We moved from Plymouth last August, and are about to come out for antifouling, anodes etc. This started me thinking about what anodes I should use. I have done a search on the forums, looked at the MG Duff website, and read the short article on anodes for freshwater in a recent PBO, but I'm still not sure what to do.
The MG Duff website says to use magnesium, but replace the anodes with zinc if the boat is in salt water for more than 14 days in the year. Most of our sailing is nipping out for the day along the Gower coast or similar, but we go off for the odd long weekend plus a one week cruise over the summer holidays. This adds up to more than 14 days. I'm not really that keen to start effing about with different anodes as a preliminary to going away for the week!
The boat is a Sun Odyssey 32, which has a golf ball shaft anode and a cone anode at the end of the shaft abutting the prop. MGD make a suitable shaft anode in magnesium, but not the cone anode. I'm very loath to leave the cone off, but worry that a zinc one will do nothing, and may upset the effectiveness of the magnesium one.
Given that there are a lot of similar boats in the marina, round the corner at the Yacht and Sub Aqua club, plus every boat in Cardiff Bay/ Penarth, I wonder what everyone else is doing. Any forumites with boats in S. Wales willing to share their thoughts?
