Huh? I thought you were on a sub 50' mono. Why can't you motor forward a bit and walk to the bow and raise the anchor? It's less than 30' deep in the harbor. Once the anchor breaks out, pick up another 10' of chain and ease away from other downwind boats, hit the autopilot on a safe course and finish raising the anchor at your leisure. Rocna's usually bring up mud from the harbor and I let them hang in the water a few feet under the surface to clean it off anyway. Good luck.
