Three WorkBoat questions for Foss Maritime

Recently, WorkBoat technical editor Bruce Buls visited Foss Maritime's Rainier Shipyard on the Columbia River to get a look at the tug Campbell Foss as it undergoes conversion from traditional propulsion to hybrid technology. Buls got a chance to speak with VP Susan Hayman and project manager Rick McKenna about just what the conversion entails for this Dolphin-class tug, similar to the Carolyn Dorothy, which was purpose-built as a hybrid.
