My little daughter is learning and playing about pirates at school and we decide to build our own ship.
We have not tried to reproduce a real ship, just to have a couple of funny weekends without TV :-)

Step 1:

Like the skull the materials are:

cardboard
tape
glue
a cork
chopsticks
rope
a cloth
paints.

We started painting the ship ribs on the cardboard.
We painted four ribs, two for the stern castle, one for the prow and another in the middle

Step 2:

We cut some bands of soft cardboard and we used three or four of them to build the ship skeleton.

Step 3:

Wait for some minutes to get consistency and then, start to glue more bands to cover the ribs.

We cut a piece of hard cardboard to create the boat deck. We stared with biggest piece and we cut step by step until get a piece which could be introduced on the boat shell.

Then we add the details, a couple of mast poles, cells under the deck,...
