The above boats are obviously well used fishing boats, one of wood and the other aluminum sheets. Same motor on both so you must be able to buy those here someplace. 

This one was not watertight anymore, not sure if it was here for repair or a final resting place. 
This last one appeared to be a very old and repaired dugout 50-60 feet long. I spotted it at one of the temples, the sides looked to be about 3 inches thick. Must be a bitch to move around.
