If wired correctly the red wire will be hot, but any wire can be hot regardless of colour if done incorrectly.
The voltage potential supplying conductor.
Where there is a red wire involved that usually indicates some type of special switching arrangement or more likely a 240 Volt circuit. In this case there will be 240 volts across the red and black and they will both be hot. Normally for 120 Volts the black is hot, the white is common and the bare wire is ground.
You can hot wire a boat. It just matters what type it is.
You have the hot wire touching ground or common on the input side of the switch.

the black wire is the hot wire

The term common is applied to the conductor that is used in any configuration of the circuit. It is easy to confuse common with the neutral wire, and in many cases this is true. A ceiling fan often has separate black and blue wires for the fan and light with the white wire, or neutral, being common to both. But common can also apply to the hot wire, as in the hot feed TO a 3 way switch or the switch leg FROM a 3 way switch to a fixture. In this situation the term common refers to the hot wire that is used any time the fixtures are lit as opposed to the "travelers" of the 3 way switches where only one or the other is powered at any one time. Any time a single hot wire powers a multi-position switch it can be referred to as the common conductor.
Very literally, hot wire is a wire that is hot. Pertaining to vehicles, to hot wire a vehicle is to start the engine or motor of the vehicles without the use of the ignition.
Your black wires are your hot wires. The white is your neutral or common. It would be best to run an equipment ground (green wire) too.

the hot wire goes to the starter and the ground wire bolts to the engine block.
yes a hot wire can kill a cardinal.
