Operator and his son were fishing on a Jon boat when they noticed weather changing and decided to head in towards ramp.  The boat was moving at a slow pace and waves were coming into the boat and filling the stern. (Operator)  father advised his son to put on the only life jacket in the vessel and jump into the water.  The father jumped in but did not have a life jacket for himself.  The boat sank and they began swimming towards an island 50-75 yards away.  Once they reached the island father hailed a boat down while his son was struggling to get on the island.  The victims were assisted onto the vessel and transported back to boat ramp.  Operator cited for not having enough pfd's on board.
