jbarnard Posted August 22, 2016 Report Share Posted August 22, 2016 So, after 13 months of waiting to get back out sailing, I have discovered the main bulkhead is essentially gone. The plan is replace it and seal the edges of the bulkhead with epoxy as well as both sides prior to installation. Has anyone else who has done this sealed the edged and surfaces with epoxy? Obviously any help keeping water out should be better, just curious if it worked very well. Ill be checking core around the chainplates while I've got it torn apart. Not looking forward to this. Any advice would be appreciated. John Link to comment Share on other sites More sharing options...

cseltzjr Posted April 24, 2019 Report Share Posted April 24, 2019 Is anyone aware of a source for either a template for the bulkhead or better yet, a plywood copy? Link to comment Share on other sites More sharing options...
DiSpencerMay Posted June 26, 2020 Report Share Posted June 26, 2020 I don't have a template source, but would be interested in finding one. Coosa board seems like the BEST option for replacing rotten marine ply, but we will see. Link to comment Share on other sites More sharing options...
JamesG Posted September 2, 2020 Report Share Posted September 2, 2020 I am working to replace mine currently. I will be making a CAD model and drawing. Shoot me a DM if any are interested Link to comment Share on other sites More sharing options...
WYCjon Posted October 14, 2020 Report Share Posted October 14, 2020 I have done this maybe 6 times I use quality marine ply (Ocoume) $$ i cut out the old and add tabs to cut out the new one accurately (cut out the old stuff with a Fein saw) (the post may need a hammer and chisel) (that area has a bit of thickened polyester that will be busted out) fix the deck that is likely rotten around the chainplates. from the bottom if the deck is not broken the gaps around the new bulkhead can be filled with thickened epoxy prior to taping in place filet around except for chainplate area tape in place both sides with 1708 dbl bias cloth 2 layers 7" and 5" (don't tape where the chainplate goes) make sure your chainplates will be in the correct place. measure from front as they are often crooked/ should be equal from stem on both sides look at the aft bulkhead too, replacing the seats as well makes the inside that is never used look nice (the seats are a bit structural) I use interlux 2000 in white to finish 3 days (one full two half) or so Link to comment Share on other sites More sharing options...
Angus Posted October 28, 2020 Report Share Posted October 28, 2020 Not certain from quick reading of class rules Must plywood be replaced with plywood ? Any core materials prohibited ? Is COOSA permitted ? Link to comment Share on other sites More sharing options...
