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.

Six Day Boat Design Seminar

Yacht and Boat Design Instruction

  • Conceptual design, the design spiral, powering concepts, preliminary lines sketching, weights

    • Six Day Schedule:

      • Day One: Conceptual design, the design spiral, powering concepts, preliminary lines sketching, weights, styling, floation principles.
      • Day Two: Hull lines drawing/computer modeling, design ratios, stability, resistance, control surfaces.
      • Day Three: Construction--materials, loads, scantling rules, design weights, ballast, sailing rigs and balance
      • Day Four: Hull Lines 2, general arrangement, tanks and machinery, propellers and shafting
      • Day Five: Exterior styling, construction details, deck plans, design integration
      • Day Six: Pulling it all together, finish drawings, final weights, budget, artwork, colour and shading.

    • Day-long Seminars and Wooden Boat Talks

      Yacht designer Tad Roberts gives a day long presentation starting in the morning with the basic physics of transverse stability and various calculation methods... Learn more >>

Spend one week (6 days) with an experienced yacht designer in a student driven program to design a boat, revise your current boat, or learn more about design in an intensive, one-on-one environment.

Two main programs are offered, focusing on either sail or powerboat design. Both hand drawing and computer design using AutoCAD (2D), Rhinoceros (3D), and FreeShip (Hull design and hydrostatics) will be taught.
