Antifoul

[Guest]

Thanks to long john silver but not near a fishermans chandlers, birchwood 33 out of the water now lots of barnacles below the mudline, cruise at 10 knots on the medway and thames esturay, need advice on the best antifoul for this area, used tiger from TCS last year but did not work as it reduced my speed by 1.5 / 2 knots.
