Hi Jeremy
Welcome to the forum.
From your 4 photos, looks like you are carving from solid ? Pine perhaps ?
As Malcolm says, we really need more info' from you – eg what does the " 1 x 12 " refer to…
For a display model, carving from solid should be fine. If you are not working from drawings /photographs of a full-size boat, I would go with what 'looks right'.
For a model to actually sail on the water, there is more design and construction involved. In particular, weight – both above and below the waterline. Will it be radio controlled etc ?
Let us know what you're aiming to do with it.
Regards,
Dave C
