Marconi rig is a sailing configuration used on most modern sailboats. It is named after the Italian inventor and engineer Guglielmo Marconi, who developed the first successful system for wireless communication. The Marconi rig features a single mast with two or more sails, including a triangular mainsail and a jib. However, there are several synonyms for Marconi rig, which are often used interchangeably. Some of the commonly used terms include Bermudan rig, triangular rig, mainsail-jib rig, or simply, a sloop. While these terms may have slight differences in their design and layout, they are all variations of the same basic Marconi-style configuration.
