A RIB under power encounters a sailing vessel on the port bow. Who gives way and what action is taken?

A. A RIB has right of way over sailing vessels due to its greater manoeuvrability

B. The RIB (power-driven vessel) gives way to the sailing vessel (under sail only) under Rule 18. The RIB must take early, substantial action to keep clear — alter course to starboard to pass astern or significantly increase distance

C. Sailing vessels must give way to all powered vessels in coastal waters

D. Right of way depends on which vessel is larger — the RIB gives way because it is smaller

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
