The design should contain a "pirate ship" instead of the Amish guy (in the link above). The ship should be inside the circle, but some part can stick out. The ship could just be a silhouette like this one http://thumb9.shutterstock.com/disp…821408.jpg but preferably looking like it is in tough/stormy waters.
A raw, rock'n'roll style is what I am looking for.
Like the Amish tshirt design, the circle should contain text. One in the top half and one in the lower half.
Top text: UNSINKABLE SHIP
Lower text: LOADED UP AND READY TO UNDOCK
