BOAT PROPELLED BY MUSCLE POWER BY CHRISTIAN PETERSEN, HAMBURG, 1897 (SECTION)

We must not fail to include in this selection a muscle-driven propeller which was patented as early as 1897 by Christian Petersen of Hamburg, Germany and is still used on lifeboats today. The transmission is driven by one pair or several pairs of foot pedals and hand levers simultaneously. In other words, it is the combined hand and foot effort which, via a chain drive, drives the propeller shaft.
