I think you have got it covered pretty much, with one exception.
When the boat feel uncontrollable in stronger winds (flighty, up and down) remember to pull everything tight. Meaning :
-1- Reduce the mast rotation in till it points to your sterns
-2- crank on the downhaul
-3- Despite angst, pull in the mainsheet and pull it really tight.
-4- then crank some more on the downhaul.
After a few tries you will find that the boat falls into a groove and you'll make lots of speed with a very docile feel to the hole boat.
Just remember to let of a significant amount of downhaul before you fully release the mainsheet. In some instances you can rip your mainsail in two when the downhaul is still fully on and you completely slacken the mainsheet. This can, however, only happen when you did point -4-
In my experience these boats do take a lot of beating and abuse, but you must be careful in being careless with them. They are so light that micro-bursts etc will pick them up and throw them about. The wind under the trampoline while driving can really lift the platform of your trailer etc.
The bloody things just want to move and fly away. That is great on the water but you'll have to keep an eye on them when parking.
The issue with the mast is that is an aerodynamically active foil. It is quite important in the high performance of the boat on the water but these good characteristic require extra attention when storing the boat.
Another thing when starting out on these boats is to keep you hand steady on the tiller. Don't bang it about as on a Hobie 16. They boat will be able to take that, but you are a crew won't.
One time I made quite a rapid bear away while I was in the trapeze. The boat cornered like a jet fighter, leaving me waterskying along side the boat at about 4 feet away. These things can happen. I got back alright after the gust when I was able to steer the boat back up again, waterskying back to the luff hull placing my feet on it and finishing the race.
