I was very concerned to find this retro-fitted, obsolete gas fitting on a recent survey of a Westerly 33 Ketch. (See photo)
The fitting had originally been plumbed to a gas fired heater which had subsequently been removed however, the feed pipe and associated valve had not been removed or adequately capped off in any way. The location of this fitting further served to compound the issue, as its location in the corridor leading to the forward cabin made it very vulnerable to being kicked open as one passed through the corridor. A Recommendation was made to have this fitting removed prior to continued use.
For an illustration of what can happen to a yacht during a gas explosion, take a look at this video of the Yachting Monthly crash test boat when the MOD fill it with Butane and light a match. Warning, DON’T TRY THIS AT HOME.
