Bermuda Triangle - gas bubbles

the bubbles effecting the boat directly doesn't sink this boat. its the fact that the boat was placed in such a way that the bubbles splash up water into the back of the boat. of course its going to sink when it fills up with water also the fact the the majority of the extra weight, cindercrete blocks, is at the stern of the boat making it ass heavy already. poorly done.

Sufficient gas displacing the water under a ship will cause it to drop, then when bubble has dispersed, and this will of course happen very quickly, the ship will sink like a stone.
