Mainland manufactured boats usually charge premium European prices now,
but the material used sucks. Service also sucks, no after-sales support!
I have a 0.8m tug boat with dual 500 motors (~6000RMB), but no gear box.
The rudder was destroyed in shipping (stupid foam packing, in which the rudder is one of the support and the rudder axle broke!) , and they don't
want to sell spare parts but expect you to buy another new boat.
