This is how we store our dinghy when anchored. We haul it up on Elysium’s hip. Years ago we tied it to a cleat and let it drag astern. Then one night in the Bahamas it went missing. I detailed that adventure here. Since then we find it more secure this way. W/ cranks it up on the halyard while I hold it off the side. Once in position she secures the halyard and I finish. I tie a stern line to the ladder chock, pull the plug on the drain (in case it rains) and then snug up the bow line. We secure the dinghy in three places. Nothing is “perfect”. Since we’ve been using this method we’ve not had any further issues with anything missing or with the dinghy. While not impossible for someone to “borrow” (steal) the engine it wouldn’t be the easiest. So far so good.
