SB 406 (continued from page 43) fixed and a portable decompression chamber.

Towing is one of the SB 406's main operations. She is equipped with two Rauma-Repola winches, one pulling 60 tons and the other 30 tons. The 2.20-inch and 1.57-inch diameter towing cables are 2,460 feet long. The towing hook, de- signed and developed in collabora- tion with the supplier, can be re- mote-released from the tug's stern control room.

There is a fast-acting, 5-ton arti- culated-boom crane installed on the stern deck; this is used for various hoisting jobs. The crane can with- stand rolling caused by even the heaviest swell. It can be used for the lifting operations involved in diving work, and carries a "basket" for lift- ing up to eight people at a time from the water.

Circle 175 on Reader Service Card co-founder of the Foundation, the 176-foot ship can carry two Harbor

Branch-designed submersibles ca- pable of diving to 2,640 feet. Follow- ing completion by Atlantic Marine the vessel was taken to Fort Pierce for fitting of a specially constructed aluminum A-frame that was de- signed and built by Harbor Branch engineers.

The new ship is the first to be built specifically for the Founda- tion. Each of the other seagoing research vessels in the Harbor

Branch fleet is capable of carrying a single submersible. They are the

Johnson, a former Coast Guard cut- ter, and the 100-foot Sea Diver, ori- ginally built for underwater archeo- logical research.

Designed by Rodney Lay & Asso- ciates of Jacksonville, the Seward

Johnson has a beam of 36 feet and draft of 12 feet. The 295-grt vessel has a capacity of 60,000 gallons of fuel, giving it a range of 8,000 nauti- cal miles at a speed of about 14 knots.

Main propulsion is provided by two Caterpillar 3512 DI diesel en- gines, each with an output of 850 bhp at 1,200 rpm. Electrical power is supplied by three Caterpillar/

Kato diesel generators, each rated 295 kw. Two Elliot White Gill thrusters are installed, each with a thrust of 7,000 pounds, and 360- degree rotatable.

Accommodations are provided for a normal complement of seven oper- ating crew, six submersible crew, and 10-14 scientists. A briefing room is equipped with video record- ers, video monitor, projection screen, and conference table. There is also a quiet lounge with technical and science library. Laboratories in- clude a submersible maintenance lab, submersible electronics repair lab, compressor room with dive locker, operations electronics lab, and wet and dry labs.

Navigation and communications electronics include: Sperry gyro- compass with three repeaters, auto- pilot, and magnetic compass; two

Furuno radars; RDI collision-avoid- ance system; Northstar Loran with

Epsco plotters and Digitac printers;

Navidyne satellite navigation unit interfaced to gyro and speed log;
