Depends what part of the planet you are from. The plans built boats can be built anywhere as strip planking materials are usually available in most places by using Western Red Cedar. Kit boats are made from DuFlex, an end grain Balsa panel manufactured in Queensland, Australia. The kit can be shipped easily in a container. Alternatively data can be supplied if you can find somewhere that manufactures a suitable core board and get them cnc cut. You would then have to tape every panel join leading to more fairing.

There is another side to the kit boat idea.
Flat panel plans might be a wee bit more practical for those of us on the other side of the planet.

Kit boats are a lot less intimidating for some people compared to building from plans where you source all your own materials, do all your own cutting, set up strong back and temporary frames, do large areas of glassing, make lots of dust from grinding and filling etc. Kit boat are self aligning requiring less skills, less mess, less VOCs, and you end up with a very light boat as the panels are heat pressed under factory conditions. The best part is much less hull fairing as only the chine taping needs to be faired. All bulkheads, beam panels, Easyrig booms, rudder components, walkways and interior fitout can be precut saving a lot of time as the cnc cutting is so accurate. The kit arrives as a stack of 2400 x 1200 DuFlex panels with prescarfed edges ready to glue side to side. To remove the parts you jigsaw the tabs holding the parts in place. Bit like a balsa aeroplane kit.
Of course there are trade offs. Kits are more expensive and the boat has a flat panel look. There are probably more home built kit catamarans now than any other building method and I suspect the people building them wouldn't have attempted a boat any other way. Flat panels don't have to look ugly either. Some designers get around this by strip planking some parts like the saloon top and gunwales to get away from the plywood look. The multi chines are mostly under water, and no they don't make any noticeable difference to performance.
I haven't drawn anything yet so not sure how good I can get a Harry to look in flat panel. Just throwing the idea out there to see what people think.

I'm not sure I see any advantage in a hard chine duflex boat. More
expensive, not pretty against faster build time. What about weight
compared with strip kiri and glass?
