1 In most situations the sailing boat is the stand-on vessel and the powerboat must give way. 2  If the sailboat is overtaking a powerboat, the powerboat is the stand-on vessel and the sailboat must give way. 3  Any boat with more maneuverability must give way to any boat with less maneuverability (see below).

1832 - Hippolyte Pixii (France) built the first dynamo using a commutator, his model created pulses of electricity separated by no current. He also by accident created the first alternator. He did not know what to do with the changing current, he concentrated on trying to eliminate the alternating current to get DC power, this led him to create the commutator.
Tesla used this high frequency current to develop some of the first neon and fluorescent lights. 1881: The first public electricity supply. The first public electricity supply was generated in Godalming, Surrey using a waterwheel at a nearby mill.1883: Magnus Volks built the first electric railway. The first electric railway opened on Brighton seafront, built by electrical engineer Magnus Volks.881: The first public electricity supply.
