    I have recently purchased a Catalina 400 after having a Catalina 30 for a number of years. One thing I have found is that the inner mounting of the stanchions is actually a self-tapping screw into the deck. These screws are now spinning in the hole and need to be fixed. I would like to through bolt them, but can not seem to get to the underside of the deck unless removing of most of the interior. Has anyone else had the same issue? What has anyone else done to rectify this situation?

    I don't have an answer for you. Have you asked on the Catalina 400 Yahoo site?

    I have seen similar-size Catalina's where the deck stanchions and pulpits were mounted over aluminum plates cast into the bottom of the laminate. Then the fastenings are threaded into these. I am not sure if the incorporated backing plates are predrilled and threaded, or this was done from the top.
    (I do not believe that Catalina would use a weak and unsafe scheme of trying to hold a stanchion with only self-tapping screws. That just does not sound like them.)
    Have you directly asked Catalina about this??

    I did check with Catalina and they indicated that some of the C400's simply had self tapping screws into the deck on the 2 inboard fasteners. The 2 outer ones were tapped into the toe rail. I agree, it does not sound like them, but it looks like this is what they did. Thanks for your response.

    I have a Mk 1 hull number 146 and my stanctions were bolted to toerail but the inside ones are screwed to the deck. I replaced almost all the screws with bolts except for the starboard gate. You can reach all of the locations between the headliner and the hull of the boat. The starboard gate is behind the galley cabinets so I passed on trying to do that one. I had to remove some of the small cabinets behind the main seating area to be able to reach the new bolt locations. I installed backing plates on all bolts. It is a 2 person job to tighten the new bolts and nuts. The headliner in our boat was not quite aligned properly so in the V berth I had to cut a small access hole behind the wood trim where the AC electrical outlet is on the port side of the V berth. The wood trim covered the hole perfectly.

    Hope this helps

    I have Hull #130 and have worked on the stanchions. The outer bolts are taped into the toe rail and the inner two are self taping screws. When I replaced some stanchions, I had considerable crevice corrosion between the stainless and the toe rail. When I remounted the stanchion, I bedded them in 5200 as a gasket to stop the crevice corrosion and now I do not rely on the bolts as fasteners.

    Byron - many thanks. My # is 76 so I am in the same age as yours. Funny it's the ones on the starboard gate that are my biggest concern. I will be looking at doing them next winter I guess! Much appreciated.
