Overview
- The accident began Friday near the bird islet De Kreupel when the anchor failed and the boat was driven onto rocks.
- With no working radio, a dead phone and little food or water, the sailor improvised a shelter from sails and waited roughly two days.
- A passing yacht spotted the wreck Sunday evening and alerted KNRM, which took the man to Andijk for care, warm clothing and lodging.
- Rescuers described him as frightened and weakened in wet, dirty clothes, saying he feared he would die before being found.
- KNRM highlighted sparse off‑season traffic on the IJsselmeer as a risk factor and, in a separate callout the same day, aided a windsurfer near IJmuiden.
