A sailboat has a preferably solid hull with lateral and longitudinal symmetry, a centrally located ring-shaped seat secured to a central portion of the top of an hull, a selectively rotatable carousel being mounted about an outer circumferential wall of said ring-shaped seat, a frame being secured to said carousel for retaining a pair of spaced apart identical sails that slant inward toward one another, a pair of removable selectively rotatable cylindrical booms being positioned on the frame with an associated halyard system for controllably furling and allowing easy reefing of the pair of sails, a pair of selectively removable rotatable hydrofoils each serving as a rudder and centerboard projecting downward from the bottom of and proximate the ends of the hull, a steering wheel being secured to the hull at the center of the ring-shaped seat and linked to each of the hydrofoils, whereby the carousel can be selectively rotated to position the sails at any desired angular position relative to the direction of the wind, without interfering with crew members who sit facing inward on the ring-shaped seat. Color-coded spaced-apart markings about a top circular portion of the carousel, relative to stripes applied to the top of the seat, show at a glance the angle of the frame to the seat, representative of the angle of the sails to the hull.
