The backstay tension should be limited to no more than 35% the breaking strain of the backstay wire. If you put too much tension in the rig, you will increase significantly the compression force in the mast and risk damage to the bottom of your boat. I know of two Express 30's where the owners put too much back stay tension and drove the mast down, and cracked the bottom of the boat, and in one case, let water in. I also know of some Viking 28's where the deck has been buckled by too much backstay tension. It would be wise to get a Loos gauge to ensure that you are not over stressing your rig.<div>

<p><font size="3" face="Times New Roman"><span style="font-size:12.0pt">We've replaced the standard "pinch the two wires together"
type of backstay adjuster with a very nice, and powerful, cascade system as
we've always had problems getting the backstay tight enough to get rid of
headstay sag while in breeze. With this new cascading system, trust me,
we're not going to have headstay problems anymore.<br>
<br>
My question? I looked below at the very front of the boat in front of
that little wooden piece, and the headstay fitting is only through bolted at
the top with no back up plate, and only one bolt in the front stem, under the
rub rail. Typical Catalina construction... cheap. <br>
<br>
Has anyone in the Wayzata fleet improved their backstay adjusting arrangement
with a more powerful cascade? And has anyone ever beefed up the headstay
piece? I'm thinking of removing it, then welding on a much longer tang, so that
I have about three bolts through the stem of the boat, not just one.
Plus, Catalina used no back up plates, only washers, which scares me. Has
anyone put on too much backstay tension and yanked the headstay fitting right
off the freaking deck? Or am I just being paranoid because these boats
are built so poorly? Thoughts on yanking off your headstay fitting would
be appreciated. If you could, please email me at <br clear="all">
