Designed by the respected team of Graham & Schlageter and first launched in 1986, this 27-footer represents a thoughtful approach to coastal cruising and weekend sailing. The Mariah 27's fiberglass construction features a fin keel with spade rudder configuration that delivers responsive handling while maintaining good directional stability. With a displacement of 5,100 pounds and ballast of 1,975 pounds, this masthead sloop strikes a practical balance between performance and comfort. The hull's 22.50-foot waterline length contributes to a theoretical hull speed of 6.36 knots, making it capable of respectable passage times under sail. The boat's 361 square feet of sail area provides adequate power in light to moderate conditions, while the SA/Displacement ratio of 19.55 suggests spirited but manageable performance characteristics. The Mariah 27's comfort ratio of 17.7 indicates a design optimized more for performance than heavy-weather comfort, making it well-suited for day sailing, coastal cruising, and club racing. Its capsize screening formula of 2.09 falls within acceptable parameters for protected waters and nearshore sailing. The nine-foot beam provides reasonable interior volume for a boat this size while maintaining good sailing characteristics. Overall, this design appeals to sailors seeking an affordable, versatile platform for exploring local waters with occasional overnight capabilities.
