i do worry at times about the strength of my carbon parts, but up to date, more than 3 years now I have never witnessed or know anyone personally who has bust apart any of the moses carbon kit, and nearly all the foilers who have progressed beyond the novice level are now using Moses carbon foils, and moses carbon masts.
My foiling buddy who a few weeks back was on his 101 mast and moses race wings 637 set up was going full speed over 30knts across our local new brighton bay area, he hit a solid sand bar and was smashed into the water, the impact was huge and from the sound of the kit hitting so hard he feared the worst as he collected in his kit far behind him, he was worried that some bad damage had been done and was surprised to see his wings were still attached and still had a one piece mast attached to his board, the hit was so solid at high speed and both feet locked down in straps,
he got back ashore and took everything apart to inspect all parts for damage/cracks /anything that was not as it should be, and he found one part that was toast, not anything Moses had made, it was one of the steel screws securing the wing to the fuse, it was bent good and proper, but everything else was fine,
take a look at the photo below at the actual screw, and imagine how much force was needed to bend such a short stainless steel screw.
To add to this myself, only 2 days ago out on my Moses foam core 633 wing and my foam core 2 year old Moses 101 mast,
the wind was high, the swell was playing, and I was powered up on my 7mtr foil kite, and then for some reason, still unknown to me, I totally messed up a very high jump losing all lift from the kite,I was high up and dropped like a house brick, and yikes! hitting the water dead flat on the wing, it made a very loud impact noise, and as i sunk below the surface I feared the worse, and turned my board over to inspect the damage I was expecting to see, but nothing at all wrong, wow! but the shock of that crash landing made me behave myself for a bit,just thinking about the impact sent shivers down my spine for a while, and back at home I took my board into my garage to check for any cracks or damage around the track area, but all good.
