cated the instruments one hour and 56 min- 

 utes after it reached the bottom. The 3 NOO 

 scientific observers on board inspected the 

 2, 900 -ft. tangled, expensive instrument array 

 to formulate recovery plans. 



On the second dive, the Aluminaut took 3 

 hours and 51 minutes to relocate the instru- 

 ments because it found another cable on the 

 bottom that had to be identified. It used its 

 two mechanical arms to lift the cable in front 

 of the viewing portholes for identification. 



The recovery was accomplished without 

 incident or damage by a unique spool device 

 attached to the nylon line and steel cables that 

 were used to suspend the instruments. 



After attaching its hook, the sub ascended 

 at speeds up to 150 feet per minute. On the 

 surface, the support vessel Privateer trans- 

 ferred the lifting line from the sub and hoisted 

 the delicate but heavy equipment on aboard. 



R. Frank Busby, NOO oceanographer and 

 project director, said the instruments were 

 in excellent condition considering their year 

 on the bottom. They were undamaged and op- 

 erating. "The data recovered from the in- 

 struments will yield vital information on the 

 oceanographic environment," Mr. Busby said. 



The Reynolds Co. believes that the Alumi- 

 naut's achievement has demonstrated that 

 what has been lost to Davy Jones may be re- 

 covered from him. 



The recovery is part of a survey program of 

 the U. S. Navy's Atlantic Fleet Weapons Range 

 off the Virgin Islands being conducted by the 

 Aluminaut. For the first time, a sub is be- 

 ing used to verify data already collected and 

 deduced by surface oceanographic vessels. 



1967 Small Boats Better Equipped, 

 Says Coast Guard 



The Coast Guard is pleased with the ef- 

 forts of the boating industry to improve its 

 products and comply with Federal boating 

 safety re quir e me nt s, states Capt. David 

 Oliver, Chief, Coast Guard Recreational Boat- 

 ing Safety Division. After they examined the 

 1967 boats at the recent Marine Trades Ex- 

 hibit in Chicago, Coast Guard of fie er s re- 

 ported considerable efforts by most boat 

 builders to meet Coast Guard regulations, 

 which apply to boat owners and operators. 



Although the enforcement of compartment 

 ducting requirements will begin June 1, 1967, 

 a few ventilation shortcomings continue. Some 

 manufacturers are using ducts and fixtures 

 too small for the space being ventilated. 

 Some cowls were installed in positions that 

 blocked them from normal air currents. 

 Combination light fixtures, curtains, seats 

 and engine covers were among the air flow 

 obstructions noted. 



The officers also reported increased con- 

 formance with proper navigation lighting 

 regulations. However, some manufacturers 

 did not know of the requirements for a three - 

 foot vertical separation between the white 

 mast head light and the colored lights, speci- 

 fied in the International Rules of the Road for 

 motorboats under 40 feet. 



On vessels displaying the lighting required 

 by the Motorboat Act of 1940, some white 

 stern lights, which should show all around 

 the horizon, were obstructed by windshields 

 and canopies. A few fixtures display light 

 beyond the permitted arc of visibility. Some 

 do not meet the prescribed arc of visibility. 



When purchasing a boat, the Coast Guard 

 advises, the buyer should ensure that it is 

 equipped in compliance with its own and state 

 safety regulations. 



Copies of these requirements are avail- 

 able from the Commandant (CHS-2), U. S. 

 Coast Guard, Washington, D. C. 20226, and 

 the state boating offices.
