Not knowing for sure your clearances here is what I would try.
1 - Permanently rig a line to a forward dock bollard near the end of your finger
2 - Permanently attach a horizontal fender
just past midway out your dock
3 - Run the line from the forward bollard on the dock to an aft starboard winch
on the boat
4- Very slowly motor
forward while taking up slack on the line until just before midships crosses the end of the finger. (once midships passes the end of the dock the bow will be blown down channel)
5- Take a couple of turns on the winch
6- Motor hard in reverse and the bow should swing port and the starboard stern will be crushing the fender
7- Once you guess that the angle is right (~30 degrees to port) cast off the line from the winch (throw it on the dock) and floor it in forward.
In very high winds single
handed this could be risky but it avoids having to back out of the channel.
If you need to take the dock line with you you could run it from a cleat, loop it on the bollard and run it back to the boat. As you motor away you'd have to play cowboy and un-lasso the bollard, while steering
and avoiding the boats on the opposite side.
Alternative 2 - Move to a port side docking
slip as soon as one is available.
Alternative 3 - Spend some time on your dock and watch how other starboard reverse berthers do it.
Alternative 4 - Probably the least stressful. Pull out turn to starboard and back out.
As a side note - even with crew getting unstuck from a leeward dock is troublesome. If you haven't done so I would take the boat out and practice pirouettes and maneuvering the boat in as close to it's own boat length as possible in various wind conditions.
Slow boat speed does not necessarily mean non-aggressive use of power. You need to know what happens when you floor it from a dead stand still in forward and reverse. You need to have a sense of how long you keep it floored to get a knot
or two of forward or reverse way. You need to know what happens when you floor it in reverse while making way at 2 knots forward.
