When approaching a UK marina or commercial port, which channels are used and in what order?

A. Hail the harbour master on Ch 16 directly — working channels are not needed for leisure craft

B. Monitor Ch 16 continuously; call the port/marina on their designated working channel (usually Ch 37 for marinas, or the port's listed channel in the almanac); move to a berth channel when directed

C. Use Ch 13 for all bridge and lock communications in any UK port

D. Call all ports on Ch 12 — this is the international port operations channel

A. To operate the radar system remotely

B. To broadcast weather forecasts to other vessels

C. To make telephone calls from the vessel to shore

D. To send a digitally coded distress alert containing the vessel's MMSI and position automatically to all DSC-equipped stations and the Coastguard

A. Maritime Mobile Service Identity — a unique 9-digit number identifying the vessel; without it a DSC distress alert cannot identify the vessel to rescuers

B. A GPS waypoint identifier used in coastal navigation

C. A VHF channel number allocated by Ofcom for distress use only

D. A vessel survey certificate number required by the MCA
