For chilly escapades to the Arctic north, the bare-bones port of Longyearbyen is your best bet. Bleak yet beautiful, it usually hosts cruise ships (as pictured), but in recent years has welcomed 45m Latitude, 42.8m Asgard and 36.4m Lars.

Start your adventure in Rabaul, a mostly abandoned town owing to the eruption of Mount Tavurvur in 1994. It does still boast a lively port – 44.8m Blue Star was spotted here in 2015 – with deep-water facilities for vessels up to 152m and a yacht club.

Those wishing to brave the angry geysers and emerald mountains of the Russian Far East should head to Provideniya, just 170nm from Alaska. Navigable only from May to December, this former Soviet military port usually hosts cargo and container ships up to 500m.

A dramatic coastline littered with waterfalls awaits visitors to this autonomous region of Portugal, 940nm from Lisbon. Follow 72.5m Axioma and 78.2m Venus to Horta Marina, which hosts yachts up to 90m and has a sports bar that doubles as a post office.

These volcanic islands off the coast of Senegal boast lush mountains and quiet beaches – head to Marina Mindelo on São Vicente, approximately 465nm from Dakar. It can host yachts up to 50m and is set in an extinct volcanic crater, now a sheltered natural harbour.
