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

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

D. 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

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

B. To broadcast weather forecasts to other vessels

C. To make telephone calls from the vessel to shore

D. To operate the radar system remotely

A. A GPS waypoint identifier used in coastal navigation

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

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

D. A vessel survey certificate number required by the MCA
