Down here in Turks & Caicos on a 2 week vacation. Awesome kiting and foiling with water so clear you cannot even see the waterline.
Unfortunately about 3 days into the trip, I was kiting at Long Bay, about a mile offshore in 8 feet of water / sand bottom when I snagged an old anchor rope at speed (22 knots). Effectively ripped the foil right out of the sliding track on the bottom of the board, and cracked one of the baseplate holes on the NF2 mast. The water is so clear that i could see the foil sitting upright on the bottom, was able to body drag over it, and catch it between my heels , lift it up and body drag in, I just let the board blow in to shore. The board took the worst of the damage, but both the foil and the board will need repairing.
Looking for advice and insights from any of you folks here on repairing either / both components.
The foil sustained absolutely no damage to the wings, fuselage, lower mast surface, but one of the front mounting holes cracked.
I still have hole location, half the original hole intact. I was thinking to rebuild the corner ear with a slurry of epoxy resin and short chopped strand glass. The fracture surface is pretty rough so I figure if I cleaned it well I had a shot at getting decent wetout / adhesion. Any comments or suggestions?
The board track took the worst of it. the brass mounting bolts effectively "pulled through" the track, breaking the tracks up and delaming a little bit of the outer level of glass on the board's bottom. The track boxes themselves appear to still be secure and well mounted into the board. I never move the foil forward and back anymore , leave it positioned at setting 4 cm. My thoughts were to convert the board to a direct fixed bolt through the board configuration. I was going to cut off the loose sections of fiberglass and the broken track "ear" segments, reglass, and refill the couple of areas on the walls of the tracks where a chunk of foam got pulled out by the track "ears" with epoxy resin. My repair questions:
- Should I go ahead and fill the sliding track channels with epoxy for extra rigitity / modulus? (I know this will add a bit of weight, but I figured not much)
- What precautions / methods should I use for sealing the 4 through board holes? I had thought about putting aluminum cylindrical tube inserts epoxied to the open foam walls of the board core. Or do I not really need to worry about this as the board won't really be in the water that much? Other proven methods for sealing through holes on foam board construction?
- I was thinking just large washers with pan head machine screws coming through from the deck with aircraft nylon insert hex lock nuts on the bottom. Alternatively I could use female threaded sex bolts like these https://www.boltdepot.com/Sex_bolts_Combo_truss_head_Stainless_steel_18-8_Coarse_(standard)_thread_3_8_barrel_(5_16-18_thread).aspx coming in from the deck and epoxied into the holes to solve the through foam sealing issues from the prior bullet.
I wont get started on this repair until I get back to the US in a week , so any and all inputs appreciated between now and then.
Thanks all for your advice. Reply here or via PM.
