Add to game boats.

A while only inflatable boat (upd: *wooden* also available and can be crafted):

You can fold/unfold it to carry in inventory and unpack near water. 

Engine - Paddles. It like pedals, but paddles.

Boats can swim by deep and shallow water. On the ground you can grab and drag the boat (or fold it to inventory).

You can fish from boat! Romantics!

This is glitching on my GCC.  stoi isn't a member of std.  Smelling another compiler issue but not in the mood to hunt it down at 0424 US Eastern.  Sorry, all.
