When fuelling a petrol-engined powerboat, what safety precautions must be followed?

A. Fuel outdoors only — no other precautions are required

B. It is safe to fuel with the engine running at idle — this prevents static discharge

C. Turn off the engine; no smoking or naked flames within 3m; fuel in well-ventilated area; do not overfill (thermal expansion); wipe spills immediately; run blower for 4 minutes and sniff the bilge for fumes before starting; carry fuel in approved jerry cans

D. Petrol fuelling is safe at any time — only diesel engines require precautions

A. The kill cord is only required when travelling above 15 knots

B. If the driver is thrown from the helm, the cord pulls the kill switch stopping the engine — preventing the vessel continuing at speed unmanned (a "circle of death" where an uncontrolled powerboat circles at full throttle striking the crew in the water)

C. The kill cord prevents fuel surging at high speed

D. Kill cords are advisory only — they are not required by law for leisure powerboats

A. Check fuel and kill cord only — all other checks are annual service items

B. Fuel (level, no leaks, correct mix if 2-stroke); oil (4-stroke: check dipstick); engine mounting bolts tight; kill cord condition and function; propeller (no damage, cotter pin present); safety equipment (lifejackets, flares, VHF, bailer, paddle); kill cord attached before starting

C. Run the engine in the water for 10 minutes before departure — no pre-launch checks needed

D. Only check fuel level — outboard engines are self-maintaining
