I'm not sure how to add material to this page, as what I have is information given to me by my late father, who was aware of this hoax when it was occurring. But doesn't that fall under the heading of "original research"? In any case, the 'monster' was being kept inside a boat house on the shore of Cartwrights Point.  My grandfather was a caretaker on Cartwright's Point in the summer, so my dad's family lived near the point in the summer months.  My dad advised me that he recalled boat loads of men out in the bay (which is called "Deadman's Bay" by the way, not Cartwright's Bay) carrying shot guns, trying to catch this "monster".  The perpetrators apparently scrapped the hoax when a fisherman in the bay had a heart attack after having the creature pop up near him.  Not sure if this material can be added or not.
