Vernon Sewell,the director owned a boat and liked to have it featured in a number of his films. In this film it provides the setting for much of the action.Sewell makes a decent attempt to try and convince us that there was a reasonable chance that the police would not be able to get enough evidence to charge him with murder. There is though one unintentionally funny scene where Bond has opened up a gas pipe in an attempt to blow up the detective.The detective keeps on trying to light his pipe with matches and a lighter but nothing works. This is rather an entertaining thriller. Obviously Sewell must have enjoyed himself particularly with all the nautical terms included in the script.
