These are the pros. The cons are basically just the opposite... Water jet: higher speed without cavitation smaller machinery (but it's basically inboard) smaller draught requirement increased manoeuvreability with a steerable nozzle (potentially) quieter doesn't chew up divers/fish Propeller(s): doesn't take up as much internal space cheaper more efficient at low speed lighter easier to clear if clogged Roger _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
