South Korea (Southern Archipelago)

Few sailors outside Asia have caught on to what the southern Korean archipelago offers, and that relative obscurity is a large part of its appeal. Roughly three thousand islands scatter across the Hallyeohaesang National Marine Park between Yeosu and Tongyeong, creating a labyrinth of narrow channels, kelp-dark passages, and protected coves that reward careful pilotage.

Depths can be capricious, tides run harder than they look on the chart, and fishing buoys demand constant vigilance — but get those variables under control and you find genuinely pristine anchorages where your only neighbours are cormorants and the occasional haenyeo diver surfacing with abalone.

Wind through summer is predominantly light southerly sea breeze, rarely punishing, which suits day-sailing hops of twenty to forty miles between island clusters. Fog patches arrive without ceremony in early June, so a working radar or chartplotter overlay is not optional. Night passages are generally calm but the volume of unlit fishing gear makes them inadvisable unless you know the area well.

Tongyeong is the natural charter base — well-serviced, with a lively fish market where you can provision cheaply on sea bream, squid, and fermented side dishes. Bareboat is available through a handful of Korean operators, though most rental contracts and marina staff work in Korean, so either bring a phrase book or book a skippered yacht for the first visit.

Yeosu offers a larger marina and better provisioning, and makes a sensible final destination if you want to finish near public transport. Border formalities are not a concern for coastal sailing, but carry your passport at every marina check-in.

May and early September offer the clearest skies and most reliable pressure; anyone uncomfortable with tidal pilotage in restricted visibility should choose September over the murky June–July transition.
