OK. Everyone says "Go slow". But this can be very dangerous advice if used in the wrong situation.

Going slow can end you up in an undockable situation if the wind and or current pushes you perpendicular to the slip!

Your engine thrust is one vector in the equation. The other two are wind and current. In essence you are solving an equation involving these three variables to end up at zero velocity, docked.

I had a slip one summer in East Hampton New York where the wind was always abeam and the slip narrow, only 1 foot wider than the boat.

Any slow approach to the slip was doomed to fail. You needed enough weigh to overcome the 20 knot breeze on the beam or else you were dead meat.

So let's not oversimplfy by saying "go slow". The proper mantra should be: "Approach the dock with an understanding of the forces involved with enough weigh to control the vessel's direction to end up docked with minimal terminal speed".

Just my 2 cents worth.
