Talking about ventilation requirements - are bilge blowers commonly used in nb or are the areas containing gas cylinders built with low level overboard vents?
I know they are more common in petrol powered craft - and that the majority of nb are diesel - but bottled gas is still heavier than air ... Trevor Tony Brooks wrote .. Rather than block the (probably) BSS required vent try hanging a piece of cloth over it about an inch away from the door & touching the floor. We do this on our front door vent and it makes a difference
