 A Bermuda or gaff mainsail lifted by a single mast with a single jib attached to a bowsprit, bent onto the forestay, held taut with a backstay.The mainsail is usually managed with a spar on the underside called a "boom".A Bermuda-rigged sloop is one of the best racing rigs per square foot of sail area as is it very weatherly, making it faster on upwind passages.
