If your board doesn't get left in the car on a blistering hot day then don't bother taking the vent screw out.
Here's why.
The pressure in the board varies linearly with the temperature. However it is degrees Kelvin, not degrees centigrade. i.e degrees relative to absolute zero which is minus 273 degrees centigrade.
So,... say the board goes from 20 degrees C in the water to 40 C in your garage.
The pressure will increase by a factor of 273 + 40 / 273 + 20
i.e. 313/293 = 1.068
i.e 6.8%
This equates to a pressure of .068 X 14.7 psi = 1psi, which is well within the capabilities of the board to cope with.
However, if the board goes from 15 degrees C in the water to 60 deg C in a locked car, the pressure is given by ((273 +60 / 273 +15) - 1 ) X 14.7 = 2.65 psi,
which is high enough to delaminate the board from the core.
So,.. if you think the temp variation will only be around 20 degrees C from sailing to storage then don't bother with the vent. Just leave it in.
If you are in the habit of leaving your gear in the car in the sun then loosen the vent plug. It only needs to be loosened a tiny bit to bleed out the pressure but then it's hard to notice if it's loose or not, so probably best to loosen it so it is visually obvious.
Mine just stays in.
i remember when the first vented boards started to turn up at the local beach.
i think it was an ahd or something like that. it was new, and shiny and everyone was well impressed.
was awindy day so said guy left it in the car, vent sealed and went sailing for a few hours. got back to find the board a big bubble in the back of his car. 
i thnik i also saw tears.
one of the wello guys a year or so ago actually melted the nose of his board in the car. the sun was like a magnifying glass on the rear window.
car=locked=bad
No wonder they say not to leave kids or pets in a locked car! The materials they make the car dash etc from must be durable..
In a wet bag there is also some capillary action and osmosis going on with the salt and moisture and this can cause the paint to blister especially on the bottom where most boards have had the paint rubbed back deliberately to improve the surface tension drag and reduce the weight of extra paint.
2nd sail
I did my usual thing & spent most of the sail subplaning with the 5.7m in c 8 -12kts.I was trying to work upwind before I "let loose". My old technique doesnt work with this board.On my narrower board I sink the windward rail & it goes upwind well & is stable.I found with the wider board sinking the windward rail made it less stable as the wider shape got pushed around more by waves & boat wake & was less stable.Also didnt help it go upwind.Ive since been told best to weight the leeward rail but keep it pretty flat.
The few times I got going I found the stance / footstraps much more ergonomic & user friendly than my old board.On my old board I have to get in & stuff around to try & get comfortable to go offwind. This one just asks to go once your in.I put the rear straps outboard as thats where i felt I needed them.
Due to being used to old 90's sails that were unstable & scary at the top of their wind range I'm used to rigging sail size for the gusts so I dont get overpowered . I think Ill have to get out of that mindset & rig larger esp as the sails I have now are more recent. I think this board will be great fun & less tiring powered up.
At the end of the day when i was buggered 
I got a 6.2 cambered race sail & went out for a run & wow! What a difference!
I'm buying the sail so at least I should get going in 10kts +
This board does amazingly tight & smooth gybes( I didnt exit on the plane but still.. ) so that Ill be great for the times you dont want to lose too much ground gybing. I read a review & my old board is designed for wider turns which probably explains why I havent had much luck gybing tighter ones..
Havent jumped it yet. By the time I actually got enough wind to plane Id been out for 2hrs & I was buggered.
Most new boards of the same size weigh half that or less.
Thought Id resurrect this post.Well its only taken 6 weeks 
but I finally got some decent wind to test out the Rocket.
YAHOOO!!!!!!!!!!!
If only I lived in WA what a ball Id have!
Anyway reasonably solid 20kts maybe occ 25kts.I was a bit worried about how it would fare as I bought it for a lightwind 5 - 15kt type board & as its 125ltres & Im 64kg I thought it might be a bit of a handful in stronger winds.
It was onshore too & I wasn't sure how Id go working out to get some space.
Makes a difference when theres enough wind to plane..working upwind is so much better! Got out in 1 tack . It blasts! Pretty choppy some 2' waves but it just spat across the top smoothly & easily.Other tack was choppier but I finally got to jump it.Wore myself out chop hopping ( or attempting them ). Got 3 in a row last run..Let out some loud " yeehaa's ! anyone on shore probably thought I was a fruitcake..
I only lasted 1/2 hr but I was starting to wear out and I figured Id start to hang off like a sack of spuds & probably start to stack it as it was lumpy & required a bit of attention.Plus I was on a high & wanted to quit while I was ahead.. Havent had a sail like that for .......??
If only I could afford to replace all my boards with Tabous...
I'm doing a Scully here..I'll resurrect this topic every now & then.Got some pics of yesterday out at Coal Point where I finally got the board to (my) top speed.They are video stills so they arent very clear.I think the board was at my upper limits as although it felt smooth & very controllable I found I was totally buggered after a few runs ( I was really overpowered at 1st).Looking at these shots I can see why! Mind you I did pick the most radical moments to capture a still shot from the video..the board actually behaves really well it's just that its getting a bit big for 20kts..
I spun out when it came down after this..I wonder why..?
Looking at this I realised I need to load up the mastbase more gybing to stop bouncing..I made the gybe though..( below) & I was very overpowered..
Boy it can move !! probably be even faster with someone else on it!
I took my old Caveman waveboard out for the first time in ages after this & it was slapping more on the waves than the Tabou although it didnt feel as tiring.
