So guys,
How do you know you are going to come down flat? (And the right way up?)

Ignoring the "old Classics" (it ended well with the boat the right way up by the way) adjusting the throttle as you take off determines the angle of flight - too much throttle can result in a vertical landing, and backing off before the crest should result in a flatter landing - of course every wave is different and you can only get good with a lot of practise!

Race boats also have bow tanks and foot throttles which help.

Sometimes you just have to hope, I wonder how many peeps on this forum have had stern landings, 'power floaters' and stalls .. me no... I've never done that

I'm glad I came across this thread. I freightened myself the other day being a dick. I was testing my new engine, a 90hp 2 stroke on my 5.3m Humber. I was on a river, the Loire, with no waves. When I saw a day boat chugging along at about 16-18knotts I thought i'd show off. I hit his bow wave, about 40 or 50cm high face on at 35knotts. I remember the water/sky/water experience. Even though the boat landed on the left hand tube the power kicked in right away and straightened everything out. It must have looked very impressive. Next time around I went slower ... a lot slower.

We have had a stern landing - see Weymouth Near Death Expereince, have had the opti screaming as we fly off a wave approximately horizontal. Some heavy cashes. But what is a 'power floater' and what is a 'stall'??

(just my descriptions) They are both wave jumps, but happen with the right/wrong mixtures of wave hight, wind and throttle. For a stall you need lots of wind straight on the nose, a big wave, and when you kill the throttle before the top, the wave passed through and you hang in the air almost still at the same angle you left the wave The power float is with same wind .. but fom behind, bout force 6 is good, trim is critical, and you power off the wave, take off and 'fly' into the back of the next one landing with a full hull length splash perfectly on the back of the next wave, then repeat ..... for ever That gets your spray rails working but throttle has to be just right, and if trim is wrong and too bow down .. look out for the mother of all stuffs
