I know how you feel. 1995 - Thames and Kennet Marina; our cruiser on the hard. My tin of anti-foul, half used, left under the boat (like many other boats). Returned to put the second coat on; the tin was there - empty. David Sherrif let me put a big sign up warning others that there was a thief amongst us (only berth holders had access). I thought there a was a code of respect between us - I was sadly let down that day and I hope the guy who nicked it dick drops off.
