It kept breaking dagger boards. The third break was inside the hull in heavy air. It broke the dagger well and tore the hull open to the point the board could plane. Couldn't get it out with that hull leeward. As we tacked the board swung under the boat and tore up the outside of the hull. I still feel it was a design flaw but a marine appraiser felt comfortable stating I had struck something. My insurance had initially denied the claim as a manufacturer defect. Hobie did offer to sell me a used hull at a substantial discount. The boat was 1 1/2 years old at this point, 1/2 year out of warranty. The hulls had worn on the bottom and been reglassed prior to this failure. It is a beautiful boat, handles well and very fast. I had it repaired and sold it this spring for 5k to a gentleman in Canada. He will mostly lake sail it and I believe thats where it belongs. The Fox is not a beach cat, maybe thats why Hobie pulled it from the Worrell 1000 several years ago.
