Sven Yrvind constructs a mold for a new boat, aligning the structure precisely along a marked center line.0:02 He staggers the support screws on either side of this line to ensure structural integrity while maintaining symmetry.0:32 The vessel measures 4.8 meters in length with a 1.3-meter beam and a 0.25-meter draft.3:40 To estimate the displacement of this new design, Yrvind uses the known displacement of his previous boat, Paradox, which weighs 640 kilograms.3:27 By applying a ratio based on the dimensions of both vessels, he calculates an estimated displacement of 840 kilograms for the new build.3:47 He accounts for 60 kilograms of food for a 100-day voyage, noting that the hull design allows for additional weight capacity if necessary.3:52 While modern builders often use Rhino software and computer modeling to determine displacement, Yrvind notes that traditional methods like Simpson’s rule and planimeters remain valid alternatives.4:48
