No, we dont have a squid living under the boat, this is the result of two of the finest minds on the boat (vortex sat this one out) trying to work out where the outlet was for the sink in the captain's cabin. We would drain the sink, but despite there being a likely outlet on the outside of the hull no water ever came out, and it wasn't pouring out inside the boat either. By the careful application of black ink, we discovered that there is indeed an outlet just under the water line, and this is the evidence.
Case solved, the company put on it's hats and went out.
