Mumby 48 hull #1 and #2. For the months of June and July we have made a 250M2 addition to the factory building and moved hull #1 to the new fit-out area. Got this done just before the onset of the monsoon rains. Built the trailer for moving and launching, it is fairly simple as…
Hot works are nearly finished on the curved hull bottom, with staff learning from the process. Most interior welding is done, and Nanni 38HP engines have been pre-fitted successfully.
Cabin redesign added a few weeks to the schedule but we are still progressing well. The cabin roof support structure was completed with cabin side and front plate installed In late December. Curves were formed in the cabin top side plates to add strength and give a better non box-like look. All cabin plate is…
At our clients request and in consultation with the designer we have done an in-house update to the cabin. Main aim to achieve here was to get better headroom in the forward half of the cabin and increase interior volume while keeping asthetics within the hull lines. A lot of discussion has been part of…
Progress for October 2024 looks good even though we lost almost a week due to Cambodia public holidays (around a full month of public holidays per year). As this is our first Mumby we have lofted topside plate and flare plates onto plywood to ensure that we have a 100% fit before cutting the 4mm…
We have installed bridge deck floor and supports, forward bridgedeck beam, aft bridgedeck beam, cockpit floor and seats. All of these parts required lofting and manual cutting with the forward and aft beams also being formed in our press brake. All bridge deck beams are now fully welded to floors.
Lofting of parts is a traditional method of creating full-scale drawings of a boat’s hull lines, frames and other parts. It’s a crucial step in boatbuilding (unless all parts are precut), ensuring accuracy and consistency in the construction process. With the Mumby 48 design only bulkheads and frames are precut using CAD software so there…
How we build a Mumby 48 at Coastal Boats (Cambodia} Co Ltd. Jig ConstructionA steel jig is dimensioned and built to stand the frames. We build all of our vessels upright and have done so for the last 25 years. We have proven (for ourselves) the advantages with this method and it is now very…
Building a performance aluminum sailing catamaran is a complex project that requires expertise in naval architecture, metalwork, and boat building.
