I have recently gone from a 21' boat with a swing keel to a 31' Catalina with a winged shoal draft keel. While no one plans to run aground I am planning for how to free my boat should that day come to pass. The wing on my Catalina is very near the bottom of the keel and as such it could make it difficult to free the boat by heeling it over to one side or the other. Is this correct? Is my best plan to deploy an anchor astern and winch my boat backwards off the rocks? How would the plan change if I was aground on mud or sand? Are there other options to consider?Gary
