This has been forsale for what seems an eternity on B&O / Ebay so i assume he will have a deal for £££
is one half of a pair that i believe were sold through ribnet a while ago (don't quote me on that) and he has used only one, also offered the choice of either the one on his boat or the spare, He was on holiday when i was looking and i ended up with something else seemed a nice bloke though
