My bow does tend to blow off quite quickly if standing for anytime at all in any sort of wind. I usually have my two young girls (2 and 3 yrs old) screaming for mom behind me in the pilothouse as I come in and on occasion I will just tell mom to deal with the kids and I will single hand the boat in. There is also a fair amount of current in our marina which complicates the matter further. I vary my approach with the slow and easy taking the tranny in and out of gear at idle. The times I come in "hot" so to speak are to deal with a strong wind off the starboard bow or a strong current. I always prefer the slow and easy approach if its possible.
Jarod, your boat sounds like my 36' Cape George cutter in terms of the underbody. It took me about 5 years (slow learner here), but I eventually discovered that I could turn her in her own length by putting the tiller over hard, throwing her into reverse and once the bow stopped turning in reference to a fixed point at the dock or on land, put her back into forward with some gas to get the boat to continue to rotate. Once I felt I was starting to move forward, back into reverse and by repeating this I could spin her around in her own length, without ever moving the rudder (turns out to be the key to the whole opeation).
The reason for noting this is that slow and easy works sometimes, but not very well when docking a full keel sailboat that perhaps some on this thread haven't done all that much of. You need to be making some headway or the rudder is useless, so trying to visualize your situation, I would bring the vessel in, rotate her so I could approach the slip from a 30 degree angle or so, then power into the slip 'hot', using reverse and the rudder hard over to counter prop walk with prop wash against the rudder.
Getting out is a whole other story since you don't have any way on so can't do much other than fend off. Since full keel boats rarely back well, you're probably stuck with the fenders.
I've made the above technique work all the way up to an 85' 100+ ton river barge, docking with the current using just power with the rudder hard over. Have to come in hot, which can freak bystanders out a bit, but it works.
