Yes those cameras are handy tools, aren't they! Just the other day I was staning on the beach and someone asked me about something inside the hull and I grabbed a nearby friend who had a camera in his hand and within seconds, we were looking at an image of the inside of the hull.
I always thought that it would be cool to get one of those cameras that the plumbers use for drains and be able to send it up the hull, past the bulkheads!
Last evening I snapped the attached photo of the upper gudgeon plate on my Mystere 6.0. The green line is on the deck plate. You can see the metal reinforcement plate around the two machine screws. It looks like we can see the gudgeon pin right through the transom.
