Hi All
Pulled out my Starboard Kode 2020 today and noticed this bit of damage.
So it is around 11cm long, and does not appear to go through as no salt marks.
Suggested that it's a crease, but would like some advice on repairing. I sail it a fair bit so don't really want to loose it to a pro to get done in the height of Adelaide sea breezes. I have some experience with glassing.
What's the thoughts?
Thanks in advance.

Step one of treatment is diagnosis. I would sand the paint off the area so you can see more clearly how bad the cracks are and how far they go
I should have mentioned that there is a main crack that is new and the other marks in the pic are from a harness hook from carrying.
However, after some sanding i caan confirm, it is a proper crack as I can bury my finger nail in, so goes straight through. So officially an 11cm crack all the way through.
All the way through.?
Looks like the bottom of the board? Generally there's at least a layer of hard foam on the bottom of the board before the styrofoam. Does the crack go through that?
Did water get inside?, gotta get it dry before doing repairs. If it is dry could inject SixTen thicken structural adhesive epoxy with a West Systems syringe into holes every 2" or so, along the crack, worked great for me on a deck delam area that gets a lot of impacts from my feet (I wrote it up under General for a Goya Bolt).
But because it is a crack, the injected epoxy will ooze out, so use 2" wide Gorilla tape along the crack to seal it with small gaps every 2" or so to insert syringe and inject epoxy. And start left going to the right, so you will see epoxy ooze out of the gap in the tape on the right side, that way you know you sealed that 2" section of the crack that is under the Gorilla tape. Since SixTen is NOT an expanding epoxy, I pumped it in with the syringe and then pushed on the deck to spread it under the deck.
Then cover sealed crack with Saranwrap and then with thick soft foam and weight down to push epoxy into all the gaps (2" think driveway pavers work good).
Of course, call West Systems and see what they say, very knowledgable technical support, with short phone wait time in US on East coast.
I can see why current board builders have stopped contributing with advice like that but it's a forum and everyone can contribute and of course people will do different methods.
No injection of resin needed, it's a crack in the glass and the foam sandwich looks intact.
Where the foam sandwich is buckled which I did to one of my boards learning to forward then over rotating and buckling 6mm H80 foam then it's a major repair!
Years ago, I've built hundreds of sandwich boards and these days most of my resin work is on my mates sailing cat.
Is the crack in between the foot straps and the mast track caused by flat landing jumps?!
Then you need to glass so that the glass doesn't go across but is angled at 45 degrees and just past the foot straps and mast track.
Sand the paint off, glass the patch, bog the patch, fair in then paint, job done 
Thanks everyone.
Decided to get the pro to do it as it might be a bit beyond me. I do want it coming out looking good and structurally strong.
Cheers Anthony
Def pro repair for that crack in a board that's jumped and even more so the end grain balsa layer is a bit different to work with.
Please dont inject resin in summer. Just asking for a melted core.

Good decision I'd say. The board isnt that old so worth spending the money on. Home repairs are good if its an old board not worth much.
These days I tend to keep my boards until they are knackered before updating. I havent sold the old ones on as they are worthless and keep them as backup in case the new board needs repairing.

It's going to need more than just injecting resin .
Absolutely. The glass is broken and thats structurally necessary.
