What is the single most important habit every boat owner with a gas cooker should follow?

A. A smell of gas is usually nothing to worry about and can normally be ignored

B. Get the gas system checked regularly (hoses, regulator, joints) as part of routine maintenance, fit a gas alarm if not already fitted, and always treat any smell of gas as a serious warning requiring an immediate, careful response — never something to shrug off

C. Gas systems on boats never need checking once correctly installed

D. Only commercial vessels need to think carefully about gas safety, not small private boats

A. Light the stove quickly to burn off the smell before it gets worse

B. Switch on the cabin lights to get a better look for the source of the smell

C. Ignore a faint smell since it is probably nothing serious

D. Never light anything, switch on anything electrical, or create any spark near the smell — gas vapour, especially LPG, is heavier than air and can build up invisibly in the bilge, ready to ignite from the smallest spark

A. Leave the gas supply exactly as it is and deal with it later

B. Only turn off the cooker control knob, leaving the main bottle valve open

C. Turn the gas supply up higher to "flush it through" faster

D. Turn off the gas at the bottle itself (the main valve), not just at the cooker — this stops any more gas flowing into the system while the leak is investigated
