Outriggers are structures that extend from the sides of a boat or canoe to increase its stability in the water. There are several synonyms for outriggers, including stabilizers, side floats, pontoon boats, and rigging systems. While these terms describe similar structures, each has its own specific application. Stabilizers are often used on larger boats to prevent roll and improve stability, while side floats are typically smaller and used on a variety of watercraft. Pontoon boats are similar to outriggers, but typically have larger, flat surfaces for seating and storage. Rigging systems can also include outriggers, but may also refer to any components used to support sails or other equipment on a boat.
