The new bro- chure, bulletin number 3386682, highlights some recently launched New Or Modified Blades Improve C-P Propeller Performance As early as the 1950s, controlla- ble-pitch propellers accounted for a substantial and steadily growing share of the propeller market world- wide. KaMeWa AB in Sweden claims to hold some 30 to 50 percent of today's CPP market, and has delivered to date more than 4,000 C-P propellers. Most of these are still in operation. The development of propellers and auxiliary equipment has made progress which can be applied to old ships to save fuel and/or improve performance. During the 60s and 70s, many ships were built with propulsion machinery and propellers adapted to higher outputs and speeds not considered economical today. Most of these ships are now operated at reduced ship speed and power. In general, the propellers no longer produce the highest possible effi- ciency given these altered condi- tions.
