San Francisco Bay, with its huge area and several ports, could more rightly be called an inland sea. Small harbors like Vallejo, major container ports like Oakland and several great bridges combine to create an immense demand for marine construction and repair. Moving a lot of that construction equipment around the Bay is an important part of the work of Port of San Francisco-based Westar Marine Services. In business since 1976, Westar has a fleet of six barges, four water taxis and nine tugs up to 3,000 hp. As a part of their fleet maintenance program the company recently purchased a pair of Cummins N14-M marine engines rated at 440 hp to repower their 56 x 14.5-ft. tug Wildcat. They had added five ft. to the boat's stern and a pair of kort nozzles with new 48-in.
