THE "P" in XP, the latest offering from X-Yachts, the builder of a fleet of outstanding racer/cruisers based in Denmark, is for "performance," and this purposeful 38-footer should deliver it in spades. Multiple keel and rig configurations are available, including, for the serious racer, an optional deep fin keel and carbon rig. The XP 38 is part of Cruising World's 2013 New Boat Showcase.
