What this video covers
Sven Yrvind constructs the hull of an experimental boat using plywood sheets, focusing on achieving a fair curve along the shear line. He uses clamps to hold the plywood in place while bending it to the frame, noting that the process requires careful, incremental trimming.0:13 To ensure symmetry between the port and starboard sides, he uses a baton to mark a fair line before cutting.1:29 He joins the plywood sections using a simple butt joint.6:52 The beam of the boat measures 122 cm at the bottom, matching the width of the plywood sheets exactly, a dimension he achieved by scaling the design by a factor of 0.913.4:21 He leaves a gap at the bow to increase volume for better performance in heavy seas.7:14 After completing the sides, he plans to install the bottom panels and reinforce the exterior with fiberglass.7:52 The total length of the vessel measures approximately 4647 mm.6:11
