What this video covers
Leo Goolden continues full-scale lofting of Tally Ho, a 108-year-old Albert Strange-designed sailing yacht, working through the body plan, waterlines, buttock lines, and diagonals on a lofting floor. Because recasting the lead ballast keel is not an option, he measures the existing keel at each station using a custom sliding-bevel-and-ruler tool, plots it directly onto the lofting floor, and fairs all other hull lines into it.▶ 1:52 Discrepancies between the keel as-built and the original lines drawing are small — a quarter to half an inch — but must be resolved because any unfair line distorts the final hull shape.▶ 2:56 Albert Strange's original table of offsets omits buttock line and diagonal measurements, so Leo scales those directly off the lines drawing and adds his own offset table entries, including an extra diagonal in a data-sparse, nearly flat section of the hull.▶ 10:21 An incomplete half-breadth plan at the bow requires cross-referencing old photographs to resolve the sheer-to-stem junction.▶ 8:52 The lofting process proves iterative: body plan sections, waterlines, and diagonals must each be faired in sequence and then revisited repeatedly, with adjustments drawn in a new color to avoid premature erasure.▶ 20:56 Leo works station by station from amidships outward, finding the ballast keel fairs into the lines drawing with minimal conflict around stations 12 and 13.▶ 12:51
