For us newbies, what is the best way to get a wing keel off a grounding (free the keel once the boat has grounded). Particularly in soft mud or sand as the Chesapeake is for most of the bay?
If you run aground hard, just wait it out if possible. If it's light, first try reverse very hard with sails dropped and if not that, then try to spin the boat and go forward.
NOT A GOOD IDEA TO HEAL THE BOAT! I've done it and don't know if I'd want to do it again. You have to heal the boat a good 45+ degrees and you are not going to be able to do that with an anchor. Put it like this, when I did it, the head sink was under water and water was rushing in. The deck was a foot under water before she broke out. That's a lot of stress on the rig. I used my spin haylard and it hasn't been the same since and I need to go aloft to find out why. We used a powerboat with 300 hp to heal the boat and pull it off and it took a lot of that 300 hp to do it so that's why I don't think you will be able to do it with an anchor and winch.
One time I got stuck and it took TowBoat US 3 hours to get me unstuck. I must have ran aground 6 times. Half of the time I've been able to get myself off with the motor or a quick U turn under sails. I hate wing keels!!!! It's soooo much easier to get a fin keel unstuck with an anchor and haylard.
But - You need to be aware that the prop wash that's generated when you're at full reverse power while stuck will stir up a lot of crud off the bottom, which will get sucked into the engine's cooling circuit. Probably be wise to check and/or replace the impeller after you do that maneuver.but the two things that have worked for me is (1) to get crew up on the bow right away (lifts the wings a little) start engine and full reverse throttle, or (2) start engine and use power to spin her in a tight circle and go back where you came from.
