Re: Stus-List C 44 Navtec backstay psi
The new HARKEN backstay adjusters are being shipped without a gage. I have a Sailtec on my C 36. It does have a gauge but I have a batten taped to the adjuster and it is marked such that it can be adjusted based on the marks which equate to known weather conditions rather than rely on the pressure gage which is barely readableAt the dock I tension it enough to make sure that the mast is not moving.

Re: Stus-List C 44 Navtec backstay psi
I think rule of thumb for hydraulic backstay is 500 to 600# at the dock and no more than 25% breaking strength maximum when sailing. For my -10 rated for 10,000#, that's around 2500#. Probably much higher for your larger backstay. Of course this is moot if your headstay isn't set properly. Some boats add a 2" toggle in winds under 15 knots to the headstay so the main can be flattened without over tensioning the genoa. Physics.

Re: Stus-List C 44 Navtec backstay psi
Agree with Josh. Just tight enough so it doesn't move much if someone grabs it. The lens on the pressure gauge on mine is so discolored and crazed I can't read the psi anyway. It's a $300 fix. I have a dinghy batten taped to it with colored tape marks. Green (light breeze), yellow (moderate breeze), red (heavy breeze), black (oh, @&%$, we're going to DIE!). I leave it at the bottom of the green. I'm guessing it's about 500 psi at the dock. Dennis C.

Re: Stus-List C 44 Navtec backstay psi
I only do about 500 pounds sitting at the dock. I might go a little higher on at a mooring just because the boat bounces around more.

Re: Stus-List C 44 Navtec backstay psi
It's almost irrelevant. I keep mine just more than slack so that if someone uses it to support themselves it won't give too much. ~500psi-ish Josh Muckley S/V Sea Hawk 1989 C 37+ Solomons, MD On Mon, Dec 2, 2019, 2:51 PM Patrick Gateley via CnC-List < cnc-list@cnc-list.com> wrote: > Hi all, > > We just had our backstay adjuster rebuilt and am wondering what PSI we > should keep it at while moored? > > Thanks > > Kari and Patrick Gateley > 1988 C 44' "Odessa" > ___ > > Thanks everyone for supporting this list with your contributions.
