Congrats on your purchase. The Sundeck on mine is teak covered. I am not sure of the actual weight it can take because it is also a working deck. On non sundeck trawlers I often see dingy mounts and deck boxes. So I am certain it could hold a Dingy. Most of the Sundeckers either have a davit and mount the dingy on the sundeck roof or use weaver davit system and mount it on the swim platfrom and fold it up.
