This vessel features fiberglass construction with a long keel configuration and masthead sloop rigging, displacing 11,200 pounds with 5,600 pounds of ballast for a 50% ballast-to-displacement ratio.

Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them.
