A watercraft having a changeable hull structure. More particularly, a watercraft having a first subassembly and one or more second subassemblies. The first subassembly includes a sponson, a flooring, and a transom, the one or more second subassemblies, each being a replaceable hull structure. The first subassembly and each of the one or more second subassemblies have commensurate shapes allowing for attachment and/or replacement of the one or more replaceable hull structures. The watercraft also includes one or more elongated connectors are used to attach the first and second subassemblies.

Watercraft with interchangeable hull structure

The invention is an aerosol search and rescue (SAR) grenade. A smoke signal is produced that is comparable to the smoke signal produced by a pyrotechnic grenade. An aspirating provides a propellant gas/air mixture to a reservoir of smoke material. A container configuration and gravity operated valve provide for a smoke plume only in the upward direction. The smoke grenade is useful in life rafts. It is also useful in inland areas posing a risk of fire.

Aerosol smoke grenade

A life raft canister is launched from a below deck doorway. A launcher is activated and pneumatically opens a below deck door, exposing the doorway. The same inflation tank inflates an elongated bladder that forces the life boat canister out of the doorway. The canister drops to the sea where the life boat is deployed from the canister. The life raft auto-inflates. As a result, a life raft is deployed from below-deck.
