What this video covers

Two 5.8-metre aluminium profiles, each 50 mm × 2.5 mm cross-section, arrive at Sven Yrvind's workshop as the base material for a new boat mould.0:54 The profiles are 6,000 mm long and must be manoeuvred in through a rear entrance because the standard door cannot accommodate their length.0:26 Once inside, Yrvind explains a change in construction method: this build will use diagonal lamination rather than a conventional approach.1:53 He plans to laminate the inside of the hull first with carbon fibre — a technique he used successfully in 1986 — before setting the mould upright.2:19 The mould will occupy one side of the workshop; a lamination table will be built on the other side.2:42 Additional space must be cleared before that work can begin.2:35 The session ends with the profiles stored and the next steps — erecting the mould and building the lamination table — identified but not yet started.
