If you were to try to explain to a non windsurfer the feeling of planing, what would you say?
Being pulled along but no feeling of where the power is coming from - just light and fast
When body, mind, starboard and nature work together to get you in a state you have never experienced. Time stops flowing, you only live the present, you feel the wind going through your body and the speed through your feet. Look back at that wake, it's so fast ! Sheet in, faster ! Breath deep: 'it's my life, I'm happy!'
Ha,ha, we should make it a competition, who can describe it better, it's a great question. I think we get some adrenaline/endorphine hit similar to drugs or chocolate, it's true that after the first time you're always wanting more.
I think it's similar to when you dream you are flying,..just by putting your arms out,.and flying,.. smooth,, silent,..and effortless,.. swoooshh 
Specially when the wind is light and you think you probably wont get planing, but you manage to kick it up onto the plane and away it goes,. 
sloop,.. slap,..skitter,..skitter,..
I always try to describe it to people as you are one with the rig. Without you, the rider, nothing would work. The energy from the wind passes through you into the board, it's like nothing else.
It is like a traction beam has hooked onto you and is accelerating you forwards into space
The moment you get on the plane...
...hook in, get into the straps, get settled and accelerate...
... that, right there, is where life begins.
Every time I rig up, get on the water and plane I get that same feeling I got when I first planned.
When I have to describe windsurfing to non sailors I tell them it's just like motorcross, speed, jumps, bumps and turns. Except when I fall off I go splash instead of splat. Usually.
Its just like if you were at work and then they said your on double bubble now for no reason and then you get that super feeling !
Its somewhere between gently following the shapes of the surface of the sea and the invisible wind on the side of your face - to concentrated focus on absorbing the bumps of the sea while feathering the sail so the power stays at max.
Its interesting. I remember my first time as well as I remember my other first time. Its certainly like an addiction. No matter how the years go past, a good session is always so thrilling.
It's like a pressure relief valve.
All your worries go away.
The board and rig start to synchronize.
Wind Blows through your hair (if you have any left 
)
Spray starts hitting you in the face and you're off in you own little sanctuary.
Jack Bruce never windsurfed but I'm sure under the influence of LSD, he was channelling planing on a windsurfer, when he wrote these words, when he was the bassist for Cream in the late 60s
You thought the leaden winter
Would drag you down forever
So you drove upon a steamer
To the violence of the sun
And the colours of the sea
Find your eyes on trembling mermaids
And you touched the distant beaches
With tales of brave Ulysses
How is naked ears were tortured
By the siren sweetly signing
For the sparkling waves are calling you
To kiss the white lace ness
And you see a girls brown body
dancing through the turquoise
And her foot prints make you follow
To where the sky loves the sea
And when your fingers find her
She drives you in her body
carving deeper ripples
In the tissues of your mind
And tiny purple fishes
Run laughing through your fingers
And you want to take her with you
To the heartland of the winter
Her name is Aphrodite
And she rides a crimson shell
And you know you cannot leave her
For you've touch the distant sands
With tales of brave Ulysses
How his naked ears were tortured
By the siren sweatly singing
