Marine propulsion research & development company, Contrapel Ltd has released details of its new propulsion system for boats – the system set to make future boats more economical, manoeuvrable, safer, stronger and better for the environment. The high-speed propeller was invented over 170 years ago and has dominated the propulsion market ever since. Despite 60 years of development, water-jets have struggled to make significant inroads. Shown to an enthusiastic marine industry for the first time at the recent Auckland On Water Boat Show, the Contrapel Hybrid Drive is about to change that.
