Mariah 30

Description

The Mariah 30 is a sleek, performance-oriented racer-cruiser designed for Midget Ocean Racing Club (MORC) competition under the International Offshore Rule (IOR), blending speed with modest overnighting capabilities. Penned by renowned naval architect Alan Andrews in 1991, it's a fractional sloop with a fin keel and spade rudder, emphasizing agility and upwind prowess in club racing and coastal passages. At nearly 30 feet, it's trailerable with a large rig and lightweight build, rewarding skilled crews with quick acceleration and a competitive PHRF rating (around 114–120). Production was limited to a handful of hulls by Mariah Yachts (a small California yard), making it a rare bird today—essentially an evolution of Andrews' Andrews 30, with a focus on West Coast racing fleets.
