Since 1998, we have been perfecting a displacement and hydrofoil drive unit that takes efficiency and effectiveness off the charts!! It requires less power to your pedals because:
*The shaft is parallel with the flow, with the drive working inside a knife-like daggerboard and streamlined bulb; propellers are protected by a streamlined skeg.
*the gear ratios are adjustable form 2.4:1 to 3.1 :1
*This means that the new drive unit will handle the biggest pitch propellers practical. For speed and touring hulls that are the most efficient (18 plus feet length, 40 lbs or lighter, less than .3 ft sq frontal wetted area**any two out of the three), it will accomodate a propeller of 24 to over 30 in pitch.
*To take the shaft torques that these props require, the torque rating is 33 footlbs at the shaft. WOW.
*the derail-resistant chain is SELF TENSIONING (Patented), with freewheeling option, reversable "booster" option, and energy "booster" (tension relief) option, watertight or racing options, watersealed option (soon).
New Drive unit stands up against the model below
and here as a displacement monohull installation:
