Found this June 2015 but was hesitant to post it because I wasn't sure if it was compelling enough. Changed my mind after trying to figure out what is was used for exactly, where it came from and how it ended up on the bottom. Same questions I have for most of the other wrecks I find.
Massive rubber raft 23 feet long with large steel U-shaped handles built into the sides. Heavy duty industrial-grade construction. In about 70 feet of water.
Ideas welcome.
