"And repairing a soft deck (non kiwi)"

sorry, can't provide any advice but that cracked me up, thanks, I needed a good chuckle.

Could you insert some some plastic/timber dowell into holes and have them protrude just above deck then work the weave around the protrusions then pull or drill out once cured.

I use board wax.
But a US box for a foil???????? how are you going to stop it from rolling? Don't trust those pegs in a Chinook strong box, I've snapped them off with a wave fin.

^^^hoops being hoops im sure its sound advice, but what we do at work is stick earplugs in the hole. Let them expand, cut off the excess.

Mike, 2 US boxes boxes, one either side of the Power Box for a flange mount on the foil.

I was considering the wax but was worried about not cleaning it off the deck properly.

Or you masking/painter tape the slot and cut it as the resin gets hard, but while it's still tacky.

Wax for the straps, painters tape for the boxes.

Some good ideas there. I'd be weary about using any kind of wax though.
The EPS in the fin box slots is a good idea. But again you can just leave it open . if any resin does get in it's easy to chip it out with a fine chisel.

Remember to chamfered the glass at the openings of each finbox.

Even better to use some silicone sealant. It will completely seal the thread forming a plug, and then it will pop out in one piece when the resin has cured. Seal, then cover with a strip of tape. When the resin is partly cured take off the tape (you might need to use a razor blade to do so). When completely cured take off the silicon plug.

Nah, I wouldn't use anything that can leave a residue like wax or silicone. It's too easy to get a little bit of it somewhere you don't realise. You will then be guaranteed of a delam.

Naish use a pair of US boxes to support their foils.

Yeah , but the problem is finding the holes after being glassed over.

Love stoney's method - simple tips are great

If not in a hurry though, with a squeegee it is possible the wet out glass right up to the box slot and not have resin dribble in. Just don't pour too close, and move it slowly and carefully when squeegeeing it out....

As an aside, I do some surfboards where they want an extra layer of glass on the bottom, so going over the fin boxes requires some care. The above method of just being careful is all good - until you have to hotcoat / flowcoat with lots of resin, its gonna get in there.
So I filled Futures boxes with 2 part silicone first (being really careful on the perimeter as you don't wanna make a non-stick area!!!!)
Advantage is with careful removal later, I can use them as plugs again :)
However for a US box that's a basic shape, Stoney's foam slab jammed in is perfect. Wish I thought of it

Thanks for the tips guys.
