The Bahia 46’s rig, common on cats today, combines a simple fractional headsail on a roller furler with a large, high-roach, full-batten mainsail fit with slides and lazy jacks. The deck-stepped mast is supported by the forestay, two swept-back side shrouds, two sets of diamond shrouds and struts between the gooseneck and the hounds. A larger, stiffer mast might not need diamonds, but they reduce weight and windage. A monohull’s narrow beam requires multiple shrouds, but a cat’s wide beam allows use of a single, strong shroud to each side. Set well aft, the shroud and mainsheet tension the headstay and are an adequate option to runners on a cruising boat.
