What this video covers
Louis Sauzedde, a 76-year-old master shipwright, demonstrates the manual drafting technique of transferring lines from a completed working drawing to a clean copy sheet using dividers, a French curve, and prick marks — no copier or CAD involved.▶ 6:02 The boat under construction is Orca, a Nova Scotian Novi lobster boat originally named Warlock, drawn at a scale of half an inch to the foot.▶ 2:39 Sauzedde explains the three standard lofting views — half-breadth (plan), profile, and body plan — and how waterlines, buttock lines, and frame sections each appear as straight lines in two views and curves in the third.▶ 14:58 He reads a sample offset from station four: 5 feet 10 inches to the centreline at the shear, and explains how a table of offsets encodes the entire hull so the drawing could be reconstructed from numbers alone.▶ 12:25 Diagonal lines in the body plan, drawn to intersect frames near 90 degrees, serve as the primary tool for fairing the hull.▶ 17:53 Moulds will be built every three feet, matching the faired sections.▶ 15:58 Sauzedde describes Novi hull geometry — V-sections forward, hollow keel developing amidships, flat run aft — and notes the finished boat will carry a Yanmar diesel and a gyro stabilisation system for the charter market.▶ 11:17
