Ship Design and AppearanceEdit
The Shark Submerge III is a small three-man submarine shaped like a shark. It was built by Franky in order to aid the Straw Hat Pirates when they ever come across a situation that requires going underwater. The passengers keep in contact with the ship above through a Transponder Snail. The Shark Submerge III has a diving limit of 5,000 meters. Going below any further than that would cause the sub to crack due to the surrounding water pressure.
