can anyone explain what the jet boats look like?
Not sure what you mean "what they look like", do you have a tour booked with some company? If so their website will most likely have pictures of the boat.
More info on what your referring to would help, as there are all types, style and models of "Jet Boats"
Most look like an ordinary alumuim hull boat with an inboard motor, but instead of a prop sticking our the back and under the boat there is what looks like a pipe sticking out. However there are outboard motor retrofit attachments to make an outboard motor into a Jet instead of a prop, so you could see an outboard motor on the Hull as well.
Mostly used in shallow water where you would damage / destroy a prop.
The Jet doesn't get damages " usually" if you hit a nugget in shallow water.
The hull comes in all sizes and shapes of from many different manufacturers. Depending what the boat is being used for will usually determine they style, 2 seater racing boat, 4 & 6 passenger fishing boat, cabin cruiser type hull and then there are the large tour type boat hulls.
Google Jet boats... and you will find a million different types
BC's leading manufacturer of jet boats...awesome
When they say "jet" they don't mean jet as in a fuel burning jet engine, it's a pump-pressurized flow of water directed through an outlet that provides propulsion. They steer by hydraulics which move the outlet pipe to direct the water in the required direction. They are a blast on a narrow river run, especially the V-8s!
The colloquial term is 'hellonwheels' but without the wheels.Edited: 7:31 pm, April 28, 2017

Years ago we ran the Shotover River in NZ on jetboats.... such fun! Would love to go again in BC.
