    I have 22 litres running,and from the factory it is quite good.
    But with a lot of attenuation material and semi-cocooning of the engines,it is great fun to sneak up on ocean kayakers from behind!

    It's the lower frequencies that get through,but i can usually get to within about 30-40 meters of them when at 7 knots.
