23 The difficulty with the analysis undertaken by Mr Gray SC is that, firstly, it may be said that there is no direct evidence of a number or even all of the matters to which he identified. However, in relation to the issue of "foreseeability", as it is understood in the case of manslaughter by criminal negligence, the Crown case is one which requires the drawing of an inference from a body of circumstances. It is not incumbent upon the Crown in order to justify the inference, that there be direct evidence of the matters particularised. Of course, the matters particularised have to be seen in the very real context of matters of which there is considerable direct evidence. That includes consideration that Mr Presland was the person who constructed the keel, the order in which events occurred culminating in the horizontal cut, particularly bearing in mind that Mr Presland's role in the fabrication of the keel, as I understand the way case has been conducted by both parties, continued after the horizontal cut. The fact that the accused was a long time employee of a factory that had an involvement in the construction of yachts from time to time and that, as I understand the Crown case as it touches upon Mr Presland, Mr Cittadini was the Managing Director of the corporation, was responsible for the supervision of the construction of the keel, which must have included to whatever extent supervision of the fabrication of it by Mr Presland. Mr Cittadini was an experienced sailor who had a personal interest in the construction of the yacht for commercial purposes and was himself a yacht owner who had previously constructed yachts in the premises. Mr Presland must have had considerable work related contact with him.
