I would add:
throwing an anchor in the pond after a capsize can make things much easier: It will auto point your bows into the wind, stop your boat from drifting during righting and will drastically reduce your jib from filling with air and your cat taking off on you once it's righted (I also furl my jib if I can)

as per the bearings in your car: " water based "goo" that can be washed out later" I hear shaving cream is great for holding the bearings in place and easily flushes out.

as per lubricating the bearings: most lubes aren't recommended for bearings. can cause them to attract sand and salts and cause flat spots. Harken does make a lube specifically for this (Called one drop I believe) and works very well
