March 12, 2021 By Shelley Byrne Two pieces of property acquired by the former Pitmarine Corporation owner have historic ties to the rivers and the Pittsburgh area. The properties were listed for sale last month following the death of Capt. Graydon “Bub” Crain in July 2020 at age 86. Crain, of Cranberry Township, Pa., was one of the founders of C&C Marine, which is now Campbell Transportation Company Inc. He was the middle son of Mason “Spike” Crain, who began Crain Bros. Inc., a well-known marine construction, towing and salvage firm. Crain left Crain Bros. in 1969 to partner with Tom Campbell to launch C&C Marine. He eventually started Pitmarine as his own venture and continued to operate it until his retirement several years ago.
