Repair Question

Reccently my pride and joy suffered a bad crack while on the roof of the car in very high winds. I've done plenty of repairs on slalom and river boats in the past but this will be the first time repairing a surski. Its a Fennix Spark in the Carbon Vaccum construction. On other kayak types I'd always do the bulk of the repair on the inside and then a cosmetic patch on the the outside. I'm debating cutting an access whole in the deck to allow repair from the inside but am worried that the Stinger will be in the way. Can anyone who is a bit more knowledgable advise if this is the case oir if there is a better way to go about it?

I've a few pictures attached of the loaction of the crack.

Cheers!
