Approach

Bow into the slip

Wind direction and strength, will it help or hinder

Wind on the nose
Wind is behind
Cross winds from the docks
Cross winds to the docks (lee shore)

Assign crew to handle lines. The lines should be coiled into two halves ready to lasso the cleats on the dock from the boat.
Rig an aft spring line and fenders on the side you are docking. Aft spring line is the first one to be put around a cleat on the dock. Aim for the cleat that will give you enough distance to bring the boat alongside safely. You can always move the lines to other cleats after the boat is stopped and in position.
Aim to stop the boat 2/3 of the way into the slip as the final stopping point
Come at minimum control speed in neutral gear unless going against strong winds
Stop the boat 1-1.5 ft from the dock without the hull touching the dock (the fenders may touch, but not squeezed to death)
Prop walk, is it helping or hurting?
Instruct your spring line handler to slip/snub the line to get the boat parallel to the dock.
Line handler will step off the boat and then make it once the is stopped alongside. If you used a midships line, it may be simpler to make the line on a boat cleat without stepping off.
Do NOT rely on the spring line to stop the boat. The spring line is the emergency brake only.
Do NOT rely on reverse power to stop the boat, it may not be available if the engine cuts out. You should be using the reverse to slow down long before you commit into the slip so that you can bail out if it doesn't work or the engine cuts out.
At about 10-ft from the entry, you should be in neutral with the boat barely moving forward and the bow slightly angled toward the side you will dock to.
With the aft spring line taut, steer away from the docks to bring in the stern. Make the stern line and then the bow line. Tie the forward spring and the outside bow line (if there is one) last.
After the boat is docked, move the aft spring line to a cleat forward of the shrouds. This is to prevent the boat from hitting the boat next to it in case the bow line breaks. Similarly, the forward spring should be short enough that if the stern line breaks, the boat will not swing out too much.
Make sure you tie a proper cleat hitch using the US method, not the RYA.

Take first turn on cleat base side opposite the entering line (load), the far horn of the cleat relative to where the line is attached on the boat.
Then go around the cleat base to capture the near horn and then cross once to come back to the far horn.
On the next cross, flip away from the entering line to lock the line so that it is exiting in the opposite direction.

Back into the slip

BSC boats assigned to the inside slips are always left docked head-in to make it easier and safer to dock. The boats assigned to the outside docks are backed in.
You can either use a pivot turn by staying close to the slip, or start from 5-6 boat lengths away and get the boat tracking in reverse.
It is important to be able to use the pivot method because in many marinas, you will not have a long runway to come into the slip.
Rig a forward spring line as the emergency brake, but also prepare your aft spring line. If there are cross winds off the dock side, you will need the aft spring line to be able to bring the bow in.
In reverse, some boats do not pivot against the forward spring line easily. On longer boats (35-ft+), a midship cleat can be easier to work with. If a midship line is used, it should lead forward to a cleat. Finding the pivot point on a boat is important. The cleat on the boat may not be in the ideal position, depending on the boat.
Aim for the cleat that will give you enough distance to bring the boat alongside safely. You can always move the lines to other cleats after the boat is stopped and in position.
As soon as the spring line handler is off the boat, the forward spring line should be made loosely and then the aft spring line should be taken around a cleat. It is easier to bring the bow in by going against the aft spring with the wheel away from the dockside.
If a midship line is used, it should be kept short and tied forward so that it can bring the boat alongside the pier sideways more easily as you are moving backwards.
In cross winds (especially winds off the docks), try to hold the boat into the wind during the approach as long as possible and steer into the slip at the last moment just before entering the slip. At that point, you should be in neutral gear so that the prop walk is not hindering your alignment. In fact, it is better to stay in neutral two lengths before entering the slip so that the prop walk is not a factor.
If you are lucky enough to have cross winds pushing you into the dock, simply stop the boat parallel to the dock at about 2 ft away and let the bow fall towards the dock and then lasso the cleats.
The speed should be minimal control speed. If you had to speed up while trying to get the boat to track straight backwards, allow sufficient time in neutral to slow down or engage the forward gear before entering the slip. Remember there are no breaks on a boat and our engines cut out all the time!
Never come into the slip fast to maintain steerage. Your goal is to position the boat correctly so you don’t need to steer much as you enter the slip. This requires a lot of practice with the particular boat to judge the momentum correctly under different conditions.
Do NOT use the spring line to stop the boat. The spring line is the emergency brake only.
Do NOT rely on forward power to stop the boat, it may not be available. Slow down the boat before entering the slip enough so that it will stop at 2/3 of the way into the slip. To do this, engage forward gear early enough so that you can bail out if it doesn't work or the engine cuts out.
