Recommended Anchor Alarm Radius

65m

65m for north anchorage. The fairway ferry traffic means regular wakes — ensure anchor is well set. South roadstead: 75m to account for deeper water and more exposure. Marstrand is a sailing race venue (Match Racing World Championship) — check event calendar for crowded periods.

About This Anchorage

Marstrand is one of Sweden's most famous sailing destinations, a car-free island dominated by the 17th-century Carlsten Fortress (Carlstens fästning) which towers above the town and is visible from 10nm offshore. The town has been a seaside resort since King Oscar II established his summer court here in the 1870s, and the Royal Swedish Yacht Club has hosted international sailing regattas here for over a century. The Match Racing World Championship (Gothia Cup) is held here each summer. Today the island offers excellent restaurants, a hotel in the historic bath house, a bakery, provisions, and the full experience of Sweden's west coast island culture. The anchorage outside the gästhamn is adequate but the island's popularity means it is very crowded in July.

  • !Lobster pots on all approaches

Skipper's Tips

  • Arrive before 10:00 in July or you will not find an anchorage position with swinging room
  • The Carlsten Fortress tour (daily in summer) is outstanding — 2-hour guided history of the 17th-century Swedish fortification
  • Marstrand has the best provisioning on the southern Bohuslän coast — supermarket, marine chandlery
  • The Match Racing World Championship (usually July) — spectacular racing to watch from the anchorage
  • Societetshuset restaurant (the old bath house) — book well in advance for dinner in July
  • Visit in late August/September for a calmer experience — facilities still open but crowds greatly reduced
