If you want to dry it out it needs crack side down and vent plug in. Bit of heat from the sun and gravity. A paper towel wick will assist also. Crack side up and particularly with vent open will do nothing, if anything allow water to seep in further.

Presumably so the air expands inside and it escapes through the crack taking any moisture with it. If you leave the air vent open air will also escape through that.

And if the crack is not all the way through, with the vent closed the expanding air has no where to go and causes a delamination.

I had something similar on my Bolt, it was just the skin that was creased in one area with no open crack. It too was in front of the foot strap, but ran along the concave deck ridge for ~1", right where my foot would hit it when bracing the board when coming off the foil and hitting a wave top.

Well if there is no water on the inside you dont need to dry it out.

And if won't matter if it's left in the sun with the vent closed. In my experience as soon as it's warm to the touch then you'll know if the crack has taken on water.

^^^ exactly - its a diagnosis too (to see if anything is coming out of the crack). It will bubble n stuff within a couple mins
Right side up won't do anything, likewise with vent plug in.

Never mind me I've only done a couple of repairs

You guys are missing my point, and his. He said there was no water coming out of the crack, but there could be moisture in it and you do not want to seal it in with epoxy! So outside in the sun with vent plug out to dry out any moisture in the crack.

I think our point is, doing a surface job, may not be sufficient. It's important to see how far the crack goes, before just sealing it up. Any moisture in the crack is irrelevant.

^^^ Yup
and how do you know the core is dry until you actually test? In the sun. Vent plug closed.
Or drill a hole and stick a cotton bud in then feel it.

Thanks, good laugh!

Thanks for all the advice guys. I ended up sanding out the crack- fortunately it didn't appear to go all the way to the foam core, and filled with epifill. Is it worth laminating some fibreglass on top of that?

yes definitely it needs the fibre strength. 3 x 4oz would do
