A guest wishes to use the yacht's swim platform and boarding ladder for swimming while the vessel is at anchor. What safety considerations does the crew need to actively manage, beyond simply allowing access?

A. It is sufficient to post a single static warning sign near the platform, with no ongoing crew supervision required

B. A lookout/safety watch for swimmers, confirming the propulsion/thrusters are secured against accidental engagement, checking for current/marine life hazards, and having rescue equipment and a means of recovery ready before guests enter the water — not simply opening the platform and walking away

C. Propulsion/thruster isolation is unnecessary as long as the engines are simply at idle

D. No active management is needed once the platform is lowered; guests are entirely responsible for their own safety

A. A code that replaced the Merchant Shipping (Load Line) Regulations in their entirety

B. A brand new code with no relationship to any previous yacht-specific regulation

C. A code that applies only to yachts under 24 metres

D. A single combined code replacing the Large Yacht Code (LY3) and the Passenger Yacht Code (PYC), now issued as MSN 1895 (M) with REG Part A and Part B respectively

A. Only yachts carrying more than 12 passengers

B. Yachts of 24 metres load line length and over, in commercial use for sport or pleasure, that do not carry cargo and carry no more than 12 passengers

C. All vessels of any length used for any commercial purpose

D. Only yachts under 24 metres in length
