acoustic and gasketing compounds.

The Claremont publication also in- cludes a "Claremont Gasketing Ma- terials" general information table.

The table gives the grade, binder, color, standard thickness, primary use, principal properties, applica- tions and maximum service temper- ature of four grades of Claremont gasketing materials.

For this operation, one of the main deck panels is placed athwartships (there is a 5- ton crane fitted aft for this purpose) to form a watertight bulkhead lo- cated about 59 feet forward of the stern ramp, thus creating a separate section. For embarking floating car- go, the stern ramp is lowered to an angle of —20 degrees below the horizontal, its end reaching about 10 feet below the waterline. This expo- sure of the stern—the so-called "open air" section—also enables the loading of cargo of unlimited height when the upper deck panels within the sternmost section are removed.

Flexibility in cargo operations is greatly enhanced by the multi- angled ramp situated within the 59- foot-long sternmost section. This ramp, the two ends of which are sep- arately height-adjustable by means of four jigger winches, is used as an extension or continuation of the ex- ternal stern ramp. This facility, to- gether with ramps on the main and weather decks (which may or may not have to be brought into use), permits direct access for wheeled cargo to any deck. The criteria for use of the main/weather deck ramps will depend on the gradient to be climbed, which in turn is deter- mined by the quay height.

The Alster Rapid has an overall length of 290.6 feet, beam of 46.9 feet, depth to main deck of 16.6 feet, and draft of 16.7 feet. Propulsion is provided by a MAN B&W 8L 28/ 32-FVO diesel engine with an out- put of 1,530 bhp, giving a speed of 13 knots.

Another unusual feature of the

Alster Rapid, which the MGN ac- cess equipment is designed to facili- tate, is its ability to load fiat-bot- tomed floating cargo such as small
