Hi, Do you have a source for a replacement hatch cover for the front hatch of our 1977 27 foot hunter sailboat? Can the original hatch material be repaired with epoxy resin? I have a small crack in the area of the deck hinge. On July 15, during a 25 knot wind on Barnegat bay, the shroud U bolts broke at deck level on a 25 foot 1977-1979 hunter sailboat. I do not know the exact year of manufacture. But it has a tiller, outboard motor, and the windows are similar to my 27 foot 1977 hunter. I do not know what the tension was on the standing rigging without sail load. However the turnbuckle hardware, which was constructed of light gauge material, was not bent and did not seem damaged. The owner's insurance company stated that the u bolts should be replaced every seven years as a regular maintenance procedure. I have never heard of this happening in the twenty three years I have owned my 1977 Hunter 27. We sail in Barnegat bay on the Jersey coast. The Bay usually has 10 to 20 knot winds during the summer. Our Hunter is insured by Boat US. I e-mailed the Boat US Seaworthy Division. They searched their insurance claims database for similar damage claims. They did not locate any demasting incidents related to deck hardware failure for the hunter sailboats. What has been your experience with the U bolt fastening system on the Hunter Sail boats? Thanks, Howie
