Take a walk through our factory and different stages of the construction of the Mumby 48 — a 48ft aluminium performance catamaran currently under construction at the Coastal Boats facility in Kampot, Cambodia. This video covers the build from fabrication to interior layout and fit-out progress, giving prospective owners a real-world look at the build quality, space, and craftsmanship that goes into every Coastal Boats vessel. The Mumby 48 is designed by naval architect Tim Mumby and built in aluminium using BV certified plate sourced in Singapore. CAD-precut bulkheads and frames are shipped to our 700m² Kampot facility where skilled fabricators and welders bring the design to life. 🔔 Subscribe for regular build updates as the project progresses. ━━━━━━━━━━━━━━━━━━━━━━━ ABOUT THIS BUILD ━━━━━━━━━━━━━━━━━━━━━━━ - Designer: Tim Mumby - Builder: Coastal Boats (Cambodia) Co Ltd - Material: BV/DNV certified 5083 aluminium - LOA: 48ft performance catamaran - Build location: Kampot, Cambodia - Capacity: 3 vessels simultaneously ━━━━━━━━━━━━━━━━━━━━━━━ LINKS ━━━━━━━━━━━━━━━━━━━━━━━ 🌐 Build log & progress: https://mumby48build.com 🚢 Coastal Boats website: https://boatsbycoastal.com 📘 Facebook: https://www.facebook.com/coastalboatscambodia ▶️ YouTube: https://www.youtube.com/@coastalboatscambodia ━━━━━━━━━━━━━━━━━━━━━━━ ABOUT COASTAL BOATS ━━━━━━━━━━━━━━━━━━━━━━━ Coastal Boats (Cambodia) Co Ltd is a custom boat builder with a 20+ year track record of delivering vessels across Cambodia, Australia, Thailand, Indonesia, the USA, Singapore, and Sweden.
