Captain van de Slampens ship, "de gouden Leuve" lying at the dock of the treasure island, somewhere in the caribbean...
The board is made from 4 tiles, each 60x60cm totaling in 120x120 cm (or 4x4). basic material is 2cm styrofoam, covered with pva and some sand. Painted with cheap acrylic paint. The water effect is cheap bath-silicone from the craft store over blue paint. 
Every treasure island needs its own skull rock...
Some pirate huts....
