So my 2019 Goya Bolt 135 has been great for foiling, but when coming off the foil in 1-3 foot waves and 15-20 knots I do plant a foot on the deck in front of the front foot strap to stabilize myself as the board hits the water. That had resulted in dents and creases (see pic. 12" to left of mast track numbers) along the ridge that circles the deck and slopes down to the mast track. There are some areas 1-2" in diameter that have flex due to the EPS core being compressed and the carbon deck not sticking to it. Was warned that over time flexing of those spots will cause cracks allowing water in followed by delamination. So I have ordered some dual density deck padding to cover the whole ridge area on each side of the mast track (9" wide x 24" long). Any thoughts on this approach? Figure dual density padding will spread the load and seal the area from water intrusion. I also put my foot there pre-foiling in light winds to level the board, and when I do the Easy beach start and uphaul the sail. Think the ridge design amplifies the impact pressures compared to a non-scooped flat deck. If I knew in advance, would have covered from the beginning. That area is also wearing out the soles of my booties because of the sanded finish. Thanks

posted this in general as well, getting comments there, so please respond to that post, thanks!

It looks like the dents and flexible spots were caused by the mast base extension hitting the board when the sail is in the water and waves are rocking the board against the mast, in addition, when the extension collar is anywhere from 18-26 cm it will also hits the board, one of the dents/grooves in the deck ridge lined up with the collar at 18 cm, that is where I put it for my 7.2 sail, will try 16 cm to see if the 7.2 downhauls good there.

Those pads added to the dented area is only masking the problem. Has this board been used a lot? If not, Id be talking to the manufacturer.

Yes, board has been used a lot in high winds and waves, with the mast base banging on the board a lot, not intentionally, but in 2'+ waves and 15-22 knots it is often hard to control the board and rig, especially if I am off-shore taking a break sitting on the board with mast laying across the board deck and waves rocking board against the mast. All the denting is along the ridge of the scooped deck (high area on deck), everywhere else is solid. Did contact Jackson at forwardmaui (Goya contact) by email, but have not received a reply.

the extension collar has been a problem for the IQ foil boards too, they made a carbon extension for the regular extension to keep the collar away from the deck so it did not dent it, bigger problem on the wide boards.

Ok, so that's great you're out a lot and the board is well broken in. I can't see a 2019 board having a delam problem, unless it had a factory defect. It's too new for a natural delam to happen, unless some water has leaked inside? Is the vent screw seal in good shape? Mine wore out within a year. I got another one and it's holding up much better.

Replaced original vent screw oring before it leaked, but I did go out once without the vent screw in place! Was light winds and a little chop before I noticed, used paper towel in vent hole to wick out water, not much got in, dried board in sun with vent screw out.

But the soft areas are only along the ridge of the scooped deck, right where the mast extension can hit it. Sail luff sleeves are padded around the extension, but in 2'+ waves the board can bang pretty hard against the mast when the sail is in the water.

If the manufacturer won't replace it as a defective board, you should fix the problem or have it repaired by a professional. I wouldn't put those pads on. The delam will just keep working its way access the deck until the delam is repaired.

Hey MagicRide, the dents and soft spots are only on the ridge of the concave deck, two plus years of the mast base banging on that high area. Dual density eva decking should strengthen those small narrow (1/2" wide) flexible areas and prevent further damage, just do not see it as a delamination warranty issue.

Seems to be a common problem with concave decks, according to local shop (who did not sell me the board) and other windsurfers (see same posting under General).

I understand what you mean by using the pads to strengthen the area or help preserve it, but those soft spots you described will slowly get worse unless you fix the root of the problem. When you push on the deck with those pads on, it will appear to be more solid, but it's what's going on underneath, that's the real issue. But good luck with the pads.

I weight every board when they are new and take pictures. That way over time I know if water is forming inside.

The padding is dual density, hard on top, soft on bottom, so any impact on the hard outer layer dissipates when it hits the soft lower level, protecting the deck, only have 1/2" wide flexible spots and they will be covered with a 9" wide piece of padding. I was told it was not delamination which spreads, but due to the EPS underneath the deck being permanently compressed and probably due to the curve at the ridge, the deck separated from the compressed EPS in just that small area, on the flatter areas the deck did not separate from the EPS. Diamond pattern Padding will also protect my booties from wearing out.

I read about expanding foam to lift foundations etc. Don't know if they would be chemically compatible with board materials though. If such a thing exists, I would think some boat repair experts would be using something similar to fill the void and provide some structural integrity. There are a lot of old boats with "soft spots "Would be cool if you could drill an 1/8" hole to inject the foam, let it expand and cure, then epoxy over the hole.
Just a thought..

You are referring to Gorilla glue.

while waiting for the padding, have been thinking about doing something like that, but the flexible areas are only 1/2" wide (top of ridge) and the deck is not cracked in those areas, so thinking of just covering it. Last thing I want to do is inject something that then expands and causes deck deformation or delamination. Dual density padding should protect it and stabilize it, since deck will be glued to the padding.

Talked to another local shop about the issue of the mast hitting the top of the concave deck ridge. They also recommended repairing the dents and flexible spots, but I said the mast will just dent the repaired areas! To which they said, get a longer bolt for the mast base so the mast hits on a flatter deck area towards the rail. I measured and think I need a M8 bolt that is 1" longer, so would have to add 1" shim under the Streamlined mast tendon base. Deck area mast would then hit is not perfectly flat, but a lot better than hitting the sharp ridge. Would still add the deck padding. What do you all think about doing that?

found 100 mm fully threaded flat head allen drive M8 at Belmetric.com. Not at boltdepot or McMaster Carr.

put pads on the deck to cover ridge dents and now have a 3/4" spacer for the mast base which makes mast hit on the downward slope of the deck past the ridge, all is good!
