Never sail alone... and don't leave if one person is still out alone at end of the day.

What is your best windsurf safety tip?
Here is mine:
Wow! That is so smart!!!!!! I am sure that nobody has thought about it before! bring a piece of rope to fix things!!!!! 
good tip, thanks, have always thought a piece of rope would be good to tow someone, but that is a more probable reason to have some rope.

I'd never sail and people might never get home if they waited for me to come in.

And that's why we have never sailed together.
It's not always (or even often) possible to sail with others so:
-Change UJ tendon often
-Use carbon booms
-Try to keep your runs short after sunset (I often fail at this one but it's a good idea)
Dont sail further away from the shoreline than you are prepared to swim... while it is blowing 25kn. For me, that is about 1km max, which is still likely to take me 1-2 hours.
If you have a sandbar between you and deeper water, go at low tide, that way waves break on sandbar leaving fairly smooth water between the beach and bar. At high tide the waves go over the bar and into the channel between the bar and shore where they can pound your equipment especially on the beach.

If you want to be safe carry a VHF radio with GPS positioning ... and do not leave your board. Few people can swim in open ocean for half a Km. How many of us have done that recently in a swimming pool? In 25 knots I doubt anybody can swim one Km. Maybe if your destination is straight downwind and there is no swell. But ... again ... be safe: do not leave your board! Ever!
I have my bit of rope wrapped around the impact vest shoulder strap.
Also have a plan for if the tendon breaks. I've looped my downhaul around the mast base and carefully sailed in with no damage to the board.

Yep that a big +1 from me

Don't sail at night !! It's irresponsible ! 
So alone, at night, sleep deprived and over 30kts is a no no then.
+1 to most of these, buts here's a lesser safety tip that I wish I knew before I broke my foot: screw the sides of your footstraps in as close together as you can get and then loosen them on top, so they're snug at the sides but you can move your feet up and down easily. 99% of the time you'll be away to get your feet out no bother, and you massively reduce the chances of your feet getting twisted.
Thinking about getting a waterproof backpack, those very small ones look comfortable enough unless you are topless.
I wish some wetsuits came with waterproof cell phone pocket.
Foam ear plugs cut in half to protect ear drums.
1m long downhaul line in board shorts pocket (excuse to wear them over shortie wetsuit).
Used to have a whistle, helmet and life jacket when I sailed alone in cold water hours away from civilization.

Also, in general, concentrate your new move technique early on then ease out and when tired (failing transitions) give up, there'll be more wind tomorrow...
