Lots of ways to do this...hard to know what's best, without knowing the amt. of wind and or current you deal with on a normal basis...I agree with the methods above..
I also coast into my slip in most conditions with the engine in neutral, by the time I'm getting off the boat it's practically stopped. ( I figure, if I have to use reverse to stop I've come in too fast.)
Do you have a mid-ship cleat..and one on the dock near the beam to match? If so, maybe attaching a short breast line 1st..to keep the beam next to the dock, gives you time to pick up/ or toss the other lines..your wife could step off with the breast line.( attaching that
1st) .and the bow line..while you pick up the stern line..or spring line.
My boat neighbor..uses his stern line to power against..not the spring..it works very well for him.
I have a method I use for single handing...but with two..I usually have the mate step off at the beam and simply hold the boat near the beam, while I pick up the other lines..
