Instructions:

1. Trim a small piece of foam approx. 3cm x 5cm into a boat shape and hollow out a small hold.
2. Cut one piece of skewer 4cm long for the mast, and another 3cm long for the boom.
3. Using waxed paper cut a small triangle for the sail.  Pierce 2 holes in each side of sail to slide the mast and boom into.
4. Press the free end of the mast into the foam at the front (bow) of the boat and press the mast and sail flat.  Tie a length of thread to top of mast.
5. Insert the ship backwards (stern first).  Use the thread to pull the sail back up into place.
