Boats are assembled by carpenters.
The Thestran and Qalian T4 boats are essentially the same in terms of materials, but different style. Kojan Style is different in terms of materials, but has the same total materials required. For sloops, T3 boats, all 3 continent styles have the same materials, just different style.
Thanks to rivensplit who provided most of the information, sarenaa and her husband on gelenia server for their checking and input and the rest of the crafters on gelenia to whom I kept asking questions and they kept replying.
