From what I've read about mines used in RC naval combat they sound pretty boring. What if there is a mine that looks like a mine going off, and if used correctly could sink a ship? I'm thinking of a CO2 canister anchored to the bottom with a pin to puncture it, rigged up to a means of triggering it from shore, and a little float to mark its location. If a ship runs over the float, and someone ashore triggers the mine then a large bubble of gas bursts to the surface and lifts the ship up. The ship then crashes back down into the water, maybe even far enough to submerge one end of the ship. If the bow goes under with the ship at speed then I can see a large amount of water flooding in through the decks potentially sinking the ship. It could also be done with a hose anchored to the bottom and a tank with a valve on shore. Opinions?
