An interesting topic
The 'new' boat has got a LPG leak detector fitted and I was looking at it at the weekend
The installation is a bit strange. The alarm unit (inc sounder) is fitted in a cupboard under the sink and the wires to the detector head go under the floor in to the bilges
Given that the floor is fairly well sealed with floor boards and carpet etc, and that all of the gas pipe work is above said floor boards and carpet, I wonder how effective it would be in the event of a leak?
How much gas would build up in the cabin space before enough seeped under the floor to set off the alarm?
