Floating Boat Dock and Gangway

Floating dock and gangway I made for my kids to dock their boats in the bathtub or pool. Modeled after the full size dock we built for our boat.

Print upside down, no supports necessary.
Hinged at the gangway/dock connection that prints in place and allows some movement.
I glued a magnet at the end of the gangway to attach it to the side of the bathtub and also used thumbtacks as cleats.

I'm new to 3d printing, only have had a printer for a couple of weeks and this is the first model I have made. If there are any comments or critiques I would be happy to hear it.
