Here are some answers, Ed.
Access to ALL bolts, unsure. I know it was an issue. I will give the boat a look see this week. I do know that you can leave a "corner" off of the top outside corners of the new bulkhead/ locker wall, and cover with interior trim. this would allow access to all through deck bolts. These potential two corner holes would be above the "drip line" on the interior of the locker, so no water into the interior of the boat. Keep in mind that the new bulkead is a 5/8" fore/aft issue where it joins the hull at the deck/hull joint, I will check to see if there was a bolt in this 5/8" wide space. I am not planning to reinstall any cabinets. I like the visual space. It makes the cave seem bigger. I might hang a storage net across the front, but looking to the future I don't anticipate trips of more than two crew for more than a week and storage seems ample w/o the old cabinets. Use the old rear/back panel of the cabinets as a starting point template for the locker wall, especially to get the ceiling/deck curve right. I also used this panel as the finished back of the locker. By luck, the depth of the new locker was just right to be able to salvage this teak veneer (sp?) plywood from the old cabinet. The boat has an extended bow roller, previous owner. The anchor shank rests a few inches forward of the manual windlass. In fact, it always rest there, so far, in perpetuity. I keep telling my wife we need to to an anchoring run through, but either the day is too good to stop sailing, or we end up testing/practicing other systems on the boat. Hey, Celebration is 4 months new to us. PS, no leaks through the anchor locker . . . so far. Scott
