yes indeed, I think because of the lengthening he ended up with a wider bow and thus thicker stempost and outer stem

Normally you do scarf the stringers as thats easy to do in advance (but you can use buttblocks if you want) usually you use buttblocks for joining the ply sheets as scarphing on the job is harder. I don't know which method the builder used in this case, but he's obviously very skilled. (Unlike me so I'd scarph the stringers and butt block the ply panels)

No need to glass the inside. 2 coats of epoxy is enough. You can pigment the last layer or paint. Or leave clear epoxy. Your choice

You will have to ask the owner that question. Personally I always like yellow hulls as they are the most photogenic and also stand out in an anchorage "which is your boat" - "the yellow one"

That is always a difficult one. And usually builders "forget" how much they spent. Obviously it all depends on where you live and what deals you can find as you build. But you should get a good idea from the materials list. Plywood costs the same per sheet whatever boat you build, as does epoxy etc. Usually its possible to find a used mast and boom if you want to save money, sometimes even sails and deck gear.

@@WoodsDesigns do you think this thing can cross the ocean?

@@kestanecihasanpubg Well it would be seaworthy enough, but minimal comfort even for one person. A better choice would be one of my larger designs - still simple hard chine plywood - like my Gypsy or Saturn www.sailingcatamarans.com/index.php/designs-2/3-25ft-to-30ft-catamarans-designs/176-gypsy

@@WoodsDesigns can this build be made out of marine grade pvc foam? Or maybe just pvc foam?
