New Company, C-Lan Marine, Will Deal In Inflatable Boats, Sales And Service The formation of a new company that deals in inflatable boats, sales and service, C-Lan Ma- rine of Riverview, Fla., was recently announced by Jim Pixton, owner and operator. C-Lan Marine will market and service all major lines of inflatable boats, including Avon, Viking, Zodiac, etc., and will offer compass repair as well as boat accessories such as anchors, inflatable pumps, motors, rope, and safety equipment.

The construction of three modern, highly effi- cient, low-cost marine railway drydocks de- signed by Crandall Dry Dock Engineers, starting with the 4,000-ton railway at Jacksonville, Fla., followed by a 3,000-ton at Pago Pago, American Samoa, then another of 4,000-ton-capacity at Punta Arenas, Chile, and finally the enlarge- ment of the railway drydock at Pictou, Nova Scotia from 2,000 to 3,000 tons, demonstrates the acceptance by shipyards of the durability, reliability and economy of railways, especially when their modern design is found quite accept- able to the environmental authorities. Also, U.S. naval authorities have granted 100 percent of their commercial capacity in their certifications of these. The railway drydock, due to its extensive underwater track, is limited in most shipyard sites as to size and capacity, but when a virgin site is chosen whose open water space is not lim- iting, they can be economically built up to 10,000 tons. This is the situation at Atlantic Dry Dock, Dartmouth Marine Slips and Pictou In- dustries where deep water was available just off- shore. Today, there are several engineering develop- ments making the larger railways more attrac- tive. 1. Welded chain with a factor of safety of 4 can be produced in either class 3 quality or the new class 4 quality, making it possible to haul 4,000- to 5,000-ton ships with only two chains versus the old four-chain and six-chain docks using cast steel chains. 2. New two-way steel track, fabricated in sec- tions 40 to 60 feet long and supported on high- capacity steel piles lends itself much better to heavy waterfront construction methods and the finished product is free from marine borer attack and, with proper paint, is very durable under water. The well-proven transfer systems adjacent to the cradles enable shipyards to use their transfer area for long duration repairs or new vesself con- struction at a very modest cost and the system does not require a wasteful cross-transfer area when real estate is at a premium. In spite of its perception as an old type dry- dock, the railway of today is a modern, well- designed and constructed facility. It can be made with declivities that suit natural shore conditions and has a superb record of safety in that the vessel is supported at all times and sur- vives remarkably even when overloaded, ne- glected and abused. Its inherent durability in the harsh environment of the sea makes it very attractive in its capacity range of 100 to 10,000 tons.
