What this video covers

Johan and Malin are constructing a watertight bed frame in the forward cabin of their boat to house a Jet Thruster.1:44 The installation requires a 4-inch through-hull fitting, which necessitates precise sealing to protect the hull core from water ingress.1:39 To ensure structural integrity, Johan cuts through the inner laminate and cedar core, fills the gap with thickened epoxy and glass, and allows it to cure before cutting the final hole.20:39 This method creates a solid glass-epoxy ring that seals the core completely.18:28 The Jet Thruster pump, which weighs 60 kilograms and moves 1,000 liters of water per minute, will be mounted on a reinforced base within this watertight box.12:38 Additionally, the crew is preparing the hull for insulation using Armacell closed-cell foam and vertical Western red cedar strips, which will later support horizontal teak interior paneling.16:08 The project involves extensive tabbing of bulkheads, foam triangles, and porthole frames to reinforce the hull-to-deck connection.7:42
