Dufour 460 Jet Thruster Docking system

I think that force is mass times acceleration...

how come there are not any forward facing thrusters to reverse out of your slip and to stop when coming into your slip. make it much handier.. i would really want some kind of ball valve also on the pump inlet.. or a slide valve.. so i could shut off water into the inlet also. like every other seacock should have. easy to build a rotating disc valve.. less chance of it clogging.
