WHAT WE DID WRONG
1. We underestimated the challenges of waters with unknown bottoms and exposed beaches and anchorages.
2. We landed our dinghy in surf and found it’s a hell of a job rowing back out through waves to calm waters.
3. I tied lousy knots.
4. With an unknown bottom, we should have rigged a trip line to the anchor. (Although the diver who eventually recovered the anchor reported it so fouled even a trip line was unlikely to resolve the problem.)
5. We overloaded the engine in futile attempts to dislodge the anchor.
