Wondering if anybody has any thoughts or knowledge about lifting & hanging a Spark 2 up (400 Ibs) on the stern davits of a sailboat so i can use it as a tender, I'm not concerned about the sailing performance as my boat is a 56' full keel heavy displacement vessel, simply wondering if anyone has done this? How they distributed the weight between the two davits ( 2 x slings?) any issues? any pictures? is it even possible?
