Propulsion Performance Products Coastal Prop Technology Offers Prop Scan Before Prop Scan entered into the U.S. market, there was virtually no way to measure the exact pitch of a propeller. Varying pitch differences between blades caused problems, and in twin screw vessels, the pitch differences between the left and right propeller led other components to become suspect. By integrating its strong computer tech- nology with newly developed repair techniques, Prop Scan helps to produce a propeller that is in tune perfectly to transmit the engine power to the water in the most efficient way possible. Circle 30 on Reader Service Card New Thrust Nozzle From Rice Propellers Rice Propellers has delivered two sys- tems for a new 98 ft. (29.8 m) tugboat being built in Chile by Detroit Diesel shipyard to work in the Maracaibo Lake in Venezuela. A sister boat (identical) to Neeltje P. The vessel has two 103 in. diameter Kort 37 system with the fol- lowing: Bollard Pull Ahead: 54.4 tons Bollard Pull Astern: 39 tons Free Running Speed: 12 knots Neeltje P was equipped with two 106 in. diameter Rice Thrust Nozzles and skewed propellers. Bollard Pull Ahead: 61.3 tons Bollard Pull Astern: 42 tons Free Running Speed: 13 knots Results were certified by Bureau Veri- tas. With its new nozzle design, Rice has eliminated the decision for users between increasing thrust but losing speed, or gaining speed and losing thrust. Now, users can have both thrust and speed with the hydrodynamic pro- file of the Rice Thrust Nozzle.

Established after U.K. Prime Minister Tony Blair challenged businesses to show that the U.K. is high in terms of creativ- ity, this distinction labels products as Fail-safe coupling joins millennium collection. being short-listed for display in the Mil- lennium Dome. Labeled in terms of its innovation and creativity, the MSC Cou- plings are lightweight and compact, reli- able with a unique fail-safe design and are known for their low linear stiffness.
