A forward mast placement and a fixed (as opposed to running) bowsprit, but with two headsails may give categorisation as a sloop.[1]: 49 A sloop is usually regarded as a single-masted rig with a single headsail and a fore-and-aft mainsail.In this form, the sloop is the commonest of all sailing rigs – with the Bermuda sloop being the default rig for leisure craft, being used on types that range from simple cruising dinghies to large racing yachts with high-tech sail fabrics and large powerful winches.A boat with a forward mast placement and a fixed bowsprit, but more than one headsail, may be called a sloop.On a masthead-rigged sloop, the forestay (on which the headsail is carried) attaches at the top of the mast.
