  • we had those thruster engines in our workshop for maintenence and they were incredible bit of kit. frightening power

  • It has 4 Jet engines just as you would find on a Boeing 747!! Stena have already sold the HSS and 2 new superferries will be introduced in Autumn 11

  • so its just a propeller thrusting water out of the back. powered by what? a diesel or a turbine engine?

  • Actually, the water jets, or 'drives' as you put on this specific ship do not fully sit below the water when the ship is stationary, about three quarters of the jets are submerged though. This is unlike Incat fast ferrys whos jets do sit fully underwater when staionary

  • looks like the jets are in a perfect position, right on the water line, putting them under water would create a shitload of drag i would think. they aren't sitting in the water because of the forward motion, if the ship was stationary you would see the drives below the water.

  • 4 General Electric Gas Turbines giving 100,000 hp, 4 Rolls Royce Water Jets. Ship has a 19,600 tons operating weight and 40 knots crusing speed. "Stena Voyager" Very impressive watching the jets from the viewing area!

  • a single propeller based drive system? my boat does exactly that lol apart from the cooling water obviously. i assume you mean a jet drive? isn't a jet ski just that?

  • why would it make it inefficient? I'm not saying that your wrong by he way i just want to know. To me it seems logical for the water outlet to be under water. it's giving the pressurised water a denser object to push against there for providing more thrust. It's like can you move away from a wall faster by pushing the wall to push yourself away from the wall, or pushing the air between you and the wall

  • By your own definition, this would qualify as a jet in that it is producing thrust by the rearward exhaust of a fluid, in this case, water. What you are thinking of is a specific type of jet, the turbojet or turbofan. In this case, the vessel uses a pump-jet. As for your second remark, oh grow up...

  • Yeah it doesn't say jet TURBINE
