Actually at one time we were two towing companies - The Bay Towing Co. and more efficient service. So the next time you see a tug that has IH on its stack remember, you're really seeing two towing companies. But it's The Houston Towing Co. In 1948 we merged these two companies also important to remember they both really work for one into the present Bay-Houston Towing Co. to provide you with a company... you. BAY HOUSTON TOWING CO. HARBOR AND COASTWISE TOWING Houston • Galveston • Corpus Christi • Freeport • Texas City tike 220 hydraulic pedestal crane and an electric, single-drum Mc- Elroy anchor-handling winch. Electronic gear includes Furuno 701 radar, Hull 922 20-channel SSB radio, Datamarine Digital 3000 fathometer, Texas Instru- ment 9900 Loran C, and two Sailor 144 MAC VHF radios. Coatings were supplied by Devoe Coatings. If you see two towing companies here, you're right! , ' J ^m FRANK CANDIES Champion Swiftships Champion Swiftships, Inc. of Pass Christian, Miss., in the spring of 1983 delivered the first of a two- tug order, the 3,900-bhp Frank Candies, to Otto Candies, Inc. of Des Allemandes, La.
