RC Sailboat stands for Remote Controlled Sailboat and is often also called a Model Sailboat.
RC Sailboats use the power of wind acting on their sails to propel the boat forward and are typically controlled by a radio transmitter. By manipulating the joysticks on the radio transmitter, radio signals are sent out and then received by the radio receiver on the boat. The receiver interprets the signals and controls accordingly the so called servos on the RC Sailboat. Those servos are battery powered electric motors which change the position of the rudder (steering the direction of the boat) and the position of the sails (allowing trimming the sails to the best location for the given direction the wind is blowing unto the RC Sailboat). In a very broad sense the operator can control through the radio transmitter the direction (via the rudder) and the speed (via the sails and strongly depending on the strength of wind) of the RC sailboat.
Types of RC Sailboats:
RC Sailboat Toys
These model sailboats are mainly made for kids. They are very easy to operate and usually control the sailboat only via a little propeller and not actually via the sail and rudder position. Their advantage is their simplicity and that they don’t rely on the wind (which means you don’t need to get your feet wet to get it back to shore or the edge of the pool. These RC Sailboats are good fun for the pool or a small pond. Example:
RC Model Sailboat
A Model sailboat or so called scaled model boat is a RC Sailboat made to the image of a particular sailboat type. Examples range from the great multi mast Schooners, Historic sailboats (see the Santa Maria) to models of the latest America cup race yachts or even a complete fantasy boat. The effort and pride of a model ship builder is to create a sailboat with the finest details matching the original boat or boat type they had in mind and make it look like a smaller version of the original. When saying “small” – these boats can be anything from a few inches to multiple feet long and include a whole range of features such as lights, sounds and even mini canon’s. There is a limitation to size vs. original measurements as RC Sailboats often have to deal with stronger winds and waves in ratio to their size compared to a full sized vessel, which can require changes to the hull, keel or the rigging of the sails.
Racing RC Sailboat
Racing RC Sailboats are made for one thing – speed. These sailboats are made from wood to high-tech material such as carbon fiber for masts. They range from just for fun RC Sailboats to specified classes defined by ISAF or individual RC Sailboat clubs. Well known classes are the International One Meter, RC Laser, Seawind or the Nirvana II. Example:
RC Bottle Boat
Bottle Boats are the low cost and not so serious alternative in RC sailing. These RC Sailboats are mostly constructed from all kind of waste items such as plastic bottles for the hull and bin bags for sails.
I hope I could give you a broad understanding of what a RC Sailboat / RC Yacht is.
Go, get yourself a RC Sailboat and fly with the wind!
