Before you start
Gather the appropriate supplies and review the specific equipment manual.
- Marine forecast
- Swell forecast
- Chart and anchor plan
Step-by-step instructions
Check offshore swell separately
Read direction, height and period even when the local wind forecast appears calm.
Study shoreline geometry
Look for open entrances and swell wrapping around headlands or reef passages.
Watch actual water movement
Observe boats already at anchor, nearby breaking seas and rebound from cliffs or sea walls.
Account for wind shifts
Recheck the shelter expected overnight rather than assuming current protection continues.
Select a backup
Have an alternative anchorage or safe harbor if motion becomes severe or holding deteriorates.
Safety note
Do not anchor in a swell-exposed location near a lee shore when forecast changes remove your escape margin.
Key takeaway
A gentle wind forecast can still produce a rough anchorage if long-period swell arrives.
