Recommended Anchor Alarm Radius
90m
90m in 4–10m on fair sand/rock. Actual depths far greater than CD — Norwegian tidal range 1-2m. Coastal anchorage — anchor alarm absolutely essential. Shore line to rocks essential. Use only in settled NE or E conditions as a transit stop. Holding is less reliable than fjord mud — check set carefully.
About This Anchorage
Osen is a coastal municipality on the Trøndelag outer coast, with a scattered archipelago of islands and skerries providing shelter from the N and E for vessels transiting the Norwegian coast north of Trondheim toward Bodø. This is a genuine transit anchorage — a safe overnight spot to break the long coastal passage between the Trondheimfjord and the Nordland county (Bodø area). The coastal approach is challenging in poor visibility as the skerries are numerous. In good conditions the outer islands offer pleasant sailing and wildlife watching — sea eagles are frequently seen in this area.

Setting Your Anchor in Trondheimfjord
Shore lines are mandatory in the Trondheimfjord system. Norwegian practice: drop a bow anchor on the shallow nearshore shelf in 4–12m, then run a stern or bow shore line to the nearest fortøyningsbolter (iron ring) set into the cliff face. Use at least 7:1 scope on the anchor rode. The Norwegian tidal range in Trondheimfjord is 1–2m (increasing toward the inner arms) — actual depths are far greater than Chart Datum; always verify with your echo sounder. Katabatic gusts from valley walls and glacier slopes can arrive without warning on clear nights — set your anchor alarm to 90m before sleeping. Under Allemannsretten, anchoring on natural shores is free for up to 48 hours. NATO restricted zones around Ørland: drone flying strictly prohibited throughout the region.

- !Limited VHF coverage in places — carry satellite communicator
- !Sea eagles: nesting pairs in the outer skerries — maintain 200m distance from nest sites
Skipper's Tips
- →This is a transit stop only: use it to break the 120nm passage between Trondheim and Rørvik
- →Monitor the 48h forecast from yr.no before committing overnight: coastal Norwegian weather changes rapidly
- →Sea eagles (havørn) are regularly seen hunting over the outer skerries — one of the finest coastal sea eagle areas in Trøndelag
- →Depart early (05:00–06:00) on a calm morning for the passage north: coastal Norwegian summer mornings are often the calmest part of the day

Set Your Anchor Alarm to 90m
In Trondheimfjord, tidal streams through the sounds and katabatic gusts from fjord walls can drag anchors without warning. Safety Anchor Alarm monitors your GPS position continuously.
