Brian interviews Johan from Quantum Sails about the sail design process for Delos 2.0, the crew's custom catamaran build.▶ 0:03 Johan walks through Quantum's proprietary FSI (fluid-structure interaction) software called IQ, which models airflow over sails and simultaneous structural deformation together — not as separate static calculations — to simulate how a sail actually trims and settles under load.▶ 2:08 The tool ingests a full sail plan with all attachment points, sheet runs, track positions, and hardware locations, then generates color-mapped strain distributions showing where loads concentrate and where fabric weakens or wrinkles.▶ 4:18 A direct comparison between Hydranet (from Dimension Polyant) and a standard six-ounce Dacron crosscut sail at identical sheet tension shows the Dacron stretching and wrinkling significantly more, particularly at the leech.▶ 7:51 The simulation also models a reefed mainsail at 16 knots true wind, assessing reef point reinforcement heights and clew position.▶ 10:19 IQ is described as a validation tool, not a design replacement — the designer's expertise and sail library still drive initial choices.▶ 8:17 The runs confirmed Hydranet as the fabric for Delos 2.0.▶ 11:52 Sails are still months from delivery at the time of recording.▶ 12:12
