I am not sure you can use 30inHg on any kind of EPS core board, preglass or not.

I had this carbon 85l wingboard, ridden to hell and sucking water from +2years of kneebrace hits.Rails were soft on top where i climb on board.
So i dried it, injected 2 part PU in the soft bits and i lammed on top of the rails with Carbon/Innegra.
Into the bag and vacuumed with a 2nd hand Gast pump ...but i forgot to open the relief valve and instead of 10inHg it went to the max (around 20inHg ?).
When i checked 2 hours later the board looked like a heroine junkie, it had lost about 30% volume.
To give it credit it still rides and jumps pretty nice, it floats like a 60l board instead of 85l ,it has all this wondrous concaves everywhere...but refuses to die or even crack.
Lesson learnt :)

When I saw this board for the first time I could have sworn I've seen him ride very similar shape of kite foil racing board.

I think kitefoil raceboards have a very parallel outline with almost no pinching at the tail.
However i remember an interview with D.Kalama in which he mentioned copying the shape of race kiteboards because they workrd real well for winging...but this was in Kalama E1 times and way before Barracuda etc...

I modified the NSI leash to use a stainless steel reversing loop and velcro. I'm going to add a little buckle to keep the velcro down.

If your velcro is opening on big spills it might be because the "end" is too thick.
If the belt strap ends but the velcro continues an inch or so it will hold closed much better.
A pull tab on the end of the strap part will still allow for 1 pull release, provided it passes well through the buckle.Easier to just see it but i cannot take pics now.

Velcro and a simple metal reversing loop is pretty bulletproof. The failure mode for plastic buckles is consistent--one leg breaks off. The buckles get tested with a straight pull, but any force applied at an angle can break one leg, and when the leg breaks it's gone. Velcro will wear out if it's not the good stuff, but if you have enough area and a reversing loop to make the stress on the velcro pretty minimal, it's reliable for decades.

That is what i use too.
Diver belt buckles were opening in big downwind spills due water force.

Velcro doubling on itself through a steel loop has not released accidentally in more than a year and it can be released quickly if in danger.

I put some carbon tube around the steel loop so it would slide on/off easier.

Random / Re: wetsuit locker for van camper

I've been thinking for a while about designing a built-in wetsuit locker in my van.

Essentially a closet made from welded HDPE like a water tank, but the right size to hang up 2 wetsuits on a hanger to drip/air dry.  It would have a drain fitting on the bottom that could go to a tube out through the floor of the van.  And maybe a ventilation fan up near the top to move some air through - possibly out the drain hole in the bottom.  It wouldn't have to move much air, just enough to keep the humidity down to outside ambient levels.

Alternatively, I might make it so that it would be mounted on the back door of the van outside.

Anyone else have a solution for drying out the wetsuit quickly when camping out of a van?

I think you are on the right track, if i ever get into campering again a wettie locker like that will be an absolute must.
Camper vans seem to be Laura Ashley designs ,cute but useless for board sport nuts.
Wettie drying locker, board&sail storage first.Then fit the optional comfort  bits around that :).

I googled this some time ago and cork can be  different qualities,ground coarser or finer, and they use different adhesives and different curing temps depending on use.So hardware store cork for construction may not work at all for us.

We live in dark times.

Wow, looks great!.
How does the PVC wrapping go?.
You shape the blank, wrap in carbon spread tow and Dcell and vacuum bag? .

 Personally i would not worry at all about the amount of Tefgel you will use on your foil (milligrams) .

Tefgel as said above, formulated to break electrical current i think.
It is electrolysis that kills the alu.

Ha ha, looks like I'm not the only one convinced by Kalama's thought processes. This is my new SUP in progress too. No tail rocker and kalama tail for a SUP that needs boardspeed to get on foil. The tradeoff is a nosedown attitude in flight. I still think a wingboard needs some tail rocker for better flight characteristics but If the SUP proves to be what people are saying I will try a rockered kalama tail on my next wing board.

I do not understand this.
Why would zero rocker at the foilbox give a nose down attitude in flight?.
Most modern  foils are designed to fly level on flat boxes, and if this is not the case you can always shim the mast plate.

I think my "shop" would fit on your workbench :)
Good job on that handle, that gap is too big and it sucks to grab empty air.

I have just ordered another pair of Takoons,1000 eur total.
Good ole Dacron and Ripstop,soft handles,no window.

After reading/watching every review i could find on Aluula,Hookipa,Xply,RS and  whatnot i still think  the price is too high for the improvements they give.

I was convinced they would be total gamechangers, IMHO they are not there yet.
