One of our members used to have a scratch built corvette that did a similar routine.
During displays, my destroyer would pop smoke to get the crowds attention, then sail past his
corvette and ignite a small firecracker. At that point his boat would sink.
As it sunk the bilge pump would kick on, and begin spinning the boat slowly and as the stern rose into
the air, he would apply dead slow to propeller all while doing a little death spin.
Two ships would then sail in close, or along and stand by while closed the scuttle valve and pumped the
ship dry... They would then escor the corvette back to shore.
Always a crowd pleaser.
