I have sliding cleats to fix to the genoa track of my Oceanis 31, which unfortunately does not have mid-ship cleats. Installation is theoretically simple, by removing a track end stop and sliding on the cleat but when unscrewing the holding screw it just turns, suggesting there may be a nut to hold underneath the deck.
The headlining panels clearly have velcro all along the back edge but I am unsure how the front fixings work - whether they are plug fixings as used in cars or whether they are concealed screws.
I don’t want to damage the headliner just to access a back nut. Any pointers would be gratefully received before I mess up.
