The data is all there in the MAIB and MCIB reports I refer to. There is only one case in the Channel where a yacht was hit in the fog, and the report suggested that better radar procedures could have prevented it.

There are absolutely no cases of a family cruiser with family on board foundering in a way that would require a lferaft. Having one is an emotional not rational decision - as suggested by the language used to justify the decision.

As I have already stated, with the possible exception of collision all cases are either in extreme conditions we are unlikely ever to experience or the result of a catastrophic failure and therefore unlikely to happen to a responsible family skipper in a well found yacht.
