Cracked my faithful starboard under my heel in front of rear footstraps the other day. Board was getting a bit soft, but dropped of the back of a swell in marginal conditions which sealed it's fate.
Due to the conditions, took about 25 minutes of slogging to get back to the car during which the affected area was totally submerged and with the crack opening forward suspect it took on a lot of saltwater.
Have been drying the board in the sun and today (day 2) looks as though most of the water has finished bubbling out, but still traces of moisture around the cracks.
My questions to the knowledgable are....
1. How long do you give a board to dry? Normally leave boards in shed for a week or so before repairs but want to be back on water asap; and
2. Was thinking of drilling a fill hole(s) and vent hole through the wood on opposing sides of the soft area and injecting a slushy mix of q-cells and epoxy in to force the deck up. Once cured, reglassing (with heavy weave) the affected area. Anyone had success with this and hints/tips appreciated.
This will be second major repair for this board so close to use-by date and not worried how it looks or weight, just need it to hang in till end of season then it can go to the windsurfer hall of fame.
Thanks
you could go to the tip and get a vacuum pump outta a fridge drill a hole in the nose and suck air thru.. Excessive water will drip out with gravity but alot will be absorbed by the foam.. Don't let the water go up the hose into the pump or your pump will implode..
Or just repair it with the water in, I'm sailing with at least a litre of water in my board and it doesn't bother me.. I carry scales to monitor the situation..
I've dried my board with the plug out in the sun, evaporates all the water and does not cause delamination.
You will never get all the h2o out 
You need to open as larger area as possible and expose as much white foam as you can the more you expose the quicker it will dry, let it drain for a few days, drying by evaporation can take weeks to months . Epoxy will not stick to wet foam, you can cut out wet foam and replace it with dry. If you inject the epoxy, do it in the coolest part of the day some epoxies generate heat which builds up inside the insulating foam and ends up melting the foam. I've injected qcell and epoxy(custard consistancy)and it has lasted another year.
Google the board lady, heaps of pics and good advice.
i have a starboard acid and there seems to be no cracks and the board doesn't get heavy when i am done but every time i open the plug i can see bubling water in the plug i recently brought it second hand so don't know history any ideas to what is going wrong
I've heard you could apply a towel or paper towel on the broken area and blow air through the vent hole, which could force the water to come out.... compressor or something similar should do it... or try with a vacuum cleaner like with vacuum pump, but open the vent plug....the 1. option is what I heard, the second is tested by me.
I'd be very careful using positive pressure, too much and board is history, even with the vent open.
There's not a lot of flow through the vent, pressure could build up beyond safe levels.
You'll more than likely burn a vacuum cleaner out, there's not enough flow to keep it cool.
