Category A Certification is the ISO's toughest standard for seaworthiness and stability. Most larger sailboats qualify, but few powerboats qualify to meet the rating’s standard for stability in seas up to 23 feet and Beaufort Force 9 (41-47 knots) winds. Happily, the MJM 53z has 50 mph speed to avoid such situations by taking advantage of even brief weather windows. Her performance and rating are made possible by a low VCG and light, strong epoxy composite construction. Seakeeper stabilizer comfort is standard.
