Hey cool Ben...Welcome

Good Aussie attitude. Simple, practical, performance oriented and no bullshit.😂

It is a fantastic boat. Anyone that has sailed on the ocean or owned a boat for a length of time, will appreciate the many design features of this boat... There are a few things I'd change. A larger salon and narrower side decks would be nice. Higher cabins so you can walk on deck, and grab a rail without crouching over and that would work well with more bridgedeck clearance. I'd gladlly take more bridgedeck clearance and take a hit on windage for that. Features I like the best. No holes in the deck except hatches--nice and dry. A dry boat is so much nicer than one with drips and leaks. The daggerboards are a fabulous design. These are personal nit picks. Overall I'd rate it one of the best designs I have seen. Congrats on a great boat. Its a good boat for a couple.

Jamie's dinghy is his "Man Cave!" Hey Jamie, nice video as usual. The Mumby design is very interesting - I'm a fan of performance oriented cats as opposed to charter boats - here in Southern California we call them pigs. One thing you haven't covered yet (that I've seen) is whether or not Tim included any sealed compartments filled with closed cell foam. It's very unusual for a large cruising cat to capsize, but if that should happen, you definitely want the boat to bob on the surface. Besides the beautiful lines and performance, the Mumby is incredibly inexpensive compared to other manufactures. Thanks for sharing your experiences, mate!

when i started building alu yachts in 85, alu was 4500 to 5000 tonne, it stayed like this til abt 5 years ago when it doubled in price, sure it is lighter than steel, grp, but too heavy for racing craft it is very fast to cut, forget cut files, loft onto the plate and rip around with a saw, even quite sharp curves can be cut so accurately that no other things like grinders and sanders are needed, it fact prepping plates always use cutters or the abrasives from grinding will embed in the plate , welding three times the speed of steel, never tig seams or butts, all you get is massive distortion

And we have the liferaft, just in case it doesn't float.

@@SailingLifeonJupiter yeah - those sliding doors in charter cats give me the chills; I guess they rely on their overweight clumsy designs as an advantage - LOL. In case of Mumby'48 I've read in forums that the foam that Tim uses has several properties and fulfils several functions: sound and heat insulation, anti-fire, aesthetics and buoyancy. Theoretically, a piece of 4mm aluminium plate with 4cm foam attached certainly wouldn't sink. I've seen a heavily modified Mumby'48 self-build with 2 escape hatches near the stairs. Although, it's in CE regulations, the safety of the escape-hatches is debatable - once you open them, there goes whatever air that was trapped in the hulls. Still, the open plan layout should make it relatively easy to swim out of the main door, no?
