Passagemaker Lite 46

Passagemaker Lite is a high-speed displacement hullform, a shape closer to a naval frigate than a fishing vessel. It has a long waterline, relatively narrow beam, and fine entry. In the manner of a frigate, there is some rise to the sections aft, but there is still deep immersion of the hull at the transom. The prismatic coefficient is fairly high (.678), and displacement is spread out along the hull to counter trimming tendencies. Twin engines of approximately 60 HP will push her up to 11plus knots and provide long range cruising speeds of 9-10 knots.
