Found about 10 litres of sea water in the bilge, as we did on approaching Sri Lanka in similar beam sea conditions. Thought it was the bilge pump outlets but crawled into the transom this afternoon to get a first hand look. Realised its a design flaw of the deck where water runs round from the high gunwale and into the transom vent/blower outlet resulting in a small waterfall back there. Running repair effected and bilges mopped out.
