What this video covers

Irwin modifies his boat to increase stability and interior space for a planned voyage to New Zealand. He removes 90.2 kilograms of internal lead ballast, which he intends to replace with 150 kilograms of ballast mounted externally and lower on the hull to lower the centre of gravity.3:09 To improve buoyancy during a potential capsize, he plans to raise the deckhouse roof by 10 centimetres.6:10 Interior structural changes include moving a bulkhead back 20 centimetres to extend the bed length to 192 centimetres and raising the bed platform by 20 centimetres to create additional storage space for food and water.4:57 He also removes an oversized, inefficient ventilation system that previously allowed water collection.0:27 The refit incorporates design lessons learned from a previous plywood boat, specifically regarding ventilation, cleat placement, and storage capacity.5:36 These modifications aim to improve both the vessel's righting moment and the habitability of the living quarters.
