Looking great Daniel, however, there is one small problem with your rudder. The bottom pintle(the strap on the rudder) should be on top of the gudgeon(the strap on the hull) this would help support the rudder. You should use small nails or a piece of wire instead of eyebolts.
I am not sure what your plans show but a lot of the ships from this era had much longer pintle posts(for a lack of better word). In fact they would have a pintle with a long post on the bottom of the hull and a gudgeon at the top of the hull. The rudder would have the opposite with a pintle with a long post at the top and a gudgeon at the bottom. The choice is yours, withstanding that your arrangement as is should be changed.
If this does not make sense let me know and I can post a picture for you
