Small tutorial: How to read a plan

[Malachi]

The lower part shows the waterlines, the upper part the sheer lines and lines which look pretty similiar to the waterlines but actually are the same as the diagonals on the body plan (red).

 

You just need the body plan to model a ship, but the waterlines and diagonals can be useful to check the model for errors/inaccuracies.

 

What´s the ship, by the way? Looks mid-19th century american to me, but most of them had a round stern *scratcheshead*

It's the North Carolina 1820.
