Somewhere I have an old letter from the Clyde Cruising Club, which was based in the Carrick, saying "Dear Sir, We regret that it has taken so long to process your membership application. Our office sank. As your cheque was water-damaged we return it and request that you send another."
I remember Zebu sinking once before alongside the quay in Conwy when she went down with the tide onto a scaffolding pipe, which pierced the hull. At low tide they repaired the hole, pumped out the water and up she came with the next tide.
