Stern thruster
On those days when the wind is dead wrong for backing out my Catalina 30 I have built a simple wooden frame that I can hang over the stern rail. On this I have mounted a 35lbs thrust trolling motor, this set to drive the stern to port. With the boats natural prop wash driving the stern to starboard and an east wind making matters worse by driving the bow to port I can still back out nicely with the little motor, this pulling the stern to port and allowing a normal exit from the marina, ie, bow first. Luckily the motor only cost me, used, $100, plus I had an old battery off my broken down old ride-on mower,so the thing cost me next to nothing. Don't need it often, but on those days I need it, I really need it. It can easily be stored in a lockwer when not in use.
