The Gunter rig is a type of sailing configuration commonly used in small sailing craft. It features a fore and aft sail set behind the mast, with the lower half of the luff attached to the mast and the upper half fastened to a vertical spar called a "yard." This rig's overall triangular shape gives it a resemblance to the Bermuda rig. The Gunter rig offers the advantage of a shorter mast, which can be easily stored within the hull when unstepped, making it convenient for towing, garage storage, or use as a tender for larger boats. Additionally, the rig's performance to windward is comparable to that of the Bermuda rig, making it popular in pleasure craft. There are various forms of the Gunter rig, each with specific characteristics and advantages, including different halyard systems and ease of reefing. This rig's design and functionality contribute to its widespread use in small sailing vessels, enhancing sea-worthiness in varying conditions.
