This old warrior sure takes a beating. This is the second time I've stuck this board's nose in the reef. Both times doing a finishing top turn on a hollow, shoulder-high inside section into about a foot and a half of water. Stuck the nose, which I'm usually quick enough to bail on in order to unload the board, but this time I actually felt the board stop

Even the Kevlar rails are no match for Okinawa reef

Dings are a part of life, and I have loads of other boards to ride, but bummed because I hate doing repair...
Anyway, here's how I get started. I use a high volume, adjustable aquarium pump in the vent plug to push water out. This pump can make as much as much as 0.035 Mpa (5 psi) on a completely closed board, but I don't usually put more than about 0.015 Mpa (2.2 psi) in a board. With this big ding, it'll only develop 0.016 Mpa (2.3 psi) at full boogie. Not only does this push any water out of the board, but air flow through the space is the only practical way to dry the board, IMO. When it stops pushing water (about 2 minutes in this case), I'll let it run for a couple of days to dry any water. Not real sure if facing the ding down works better, but it feels right...LOL Maybe if the board was full of water.
The pain.

The system.
The set up.
The pressure.

The bubbles
In a few days, I'll dissect it, and see how bad it really is.
