In a fleet including the cream of the Open class monohulls, this was one of the most impressive gatherings of high speed ocean racing yachts ever assembled. A week into the race and of those 18 only four - sorry three (another's just capsized) - trimarans are still out on the race course competing. So are the 60ft trimarans too flimsy? Have they become too optimised for round the cans grand prix and not for the rigours of the open ocean? Or is it just plain stupid to start a race across the north Atlantic in November? The main reason for the carnage in the Route du Rhum was the severe weather during the first week when all the boats found themselves sailing into 40 knot headwinds and some unfortunate boats in the southeast quadrant of the depression experienced winds of 60-70 knots. These conditions were exceptional - the forecast charts only predicted winds of 35-45 knots - and are thought to be the strongest winds the 60ft tris have encountered in recent years. But then big conditions are not out of the ordinary when setting sail from northern Europe in November. Trimaran designer Nigel Irens believes that the race organisers need to
