I have a copy of the same letter that came with our 35-2, #270. I also have a table showing the pressures vs lbs force. I'll try to remember to share it.
Some great insight on this thread! Our backstay adjuster needs a rebuild, and won't go beyond about 800psi, but that is still enough to make the head door difficult to latch. It has only come open once in heavy seas though. With two forestays, I'm not sure how that affects things. We also have a new holding tank under the v-berth; I wasn't aware the original one was outboard of the head it sounds like? -- Shawn Wright shawngwri...@gmail.com S/V Callisto, 1974 C&C 35 https://www.facebook.com/SVCallisto On Wed, Jun 10, 2020 at 7:39 PM david--- via CnC-List <cnc-list@cnc-list.com> wrote: > I am not sure this picture will be small enough for the list.
