A few years ago I saw a cat with a man in a wheelchair aboard. The crew handled it quite well. They used the dinghy davit with a bosun chair for the dinghy in and out. At the dock they had a two man contraption to swing the young man out of the dingy and into his chair. Two of the guys were quite fit and the young man in the wheelchair was probably 25. His chair had big sand tires on it. They had the drill down pat. I thought what wonderful friends this guy must have to accommodate him in such a clever manner.
