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.
One of Teslaâs crowning moments was his demonstration of an AC electric generator that transported electricity over large distances. He has a patent (US Patent 390,721) for this invention.
