<DIV><FONT size=2>We are a Southern California based Capri 25. In fact, we
used the factory tangs as attachment points for our cascading backstay, and upon
that backstay upgrade, I decided that I'd better beef up our headstay
attachment.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>My plan is simply to leave the factory bow fitting in place,
and to simply install a new tang, through bolted to the bow. That
tang will not be welded to the bow fitting, as I don't feel like going through
the gyrations of removing that factory fitting so as to take it to a
welder. Instead, I'll simply install the new bow tang, laying it right
over the existing factory piece. Thus, the headstay will attach to BOTH
the existing factory piece, AND the bow tang through bolted to the
bow.</FONT></DIV>

And as to the Wayzata fleet? Why not change your bylaws and allow the
backstay upgrade? Its much nicer than the "pinch the wires together"
system.</FONT></DIV>

-- Reminder on WYC Capri 25 Fleet Rules</DIV>
<DIV><BR></DIV>
<P>Greetings Everyone;</P>
<P>I would like to remind all the local Capri 25 Fleet members that are
reviewing this discussion thread that the installation of a cascaded backstay
is a departure from the local fleet rules - A cascaded backstay was
installed on Capri 25 #009 "Divine Inspiration" and was later disallowed
because it altered the original running rig as defined by the local rules. For
all the out of town Capri's its a great way to get additional purchase and
manual force to reduce headstay sag and flex the mast, bending the center
forward to force for a flatter main in heavy air. </P>
<P>Engineering Notes: Cascading Backstays and Headsail Tacks</P>
<P>Backstay -- The angle of the backstay is very important due to the roach of
the standard mainsails. PHRF mains that conform to the original Capri 25 rules
(the PHRF standard) have a greater roach than our local Capris. This means
that cascading blocks should use the original chainplate positions on the
stern and not be lead directly to the eye on the cockpit deck aft of the
rudder post. That eye is for the adjuster rig only. If you cascade to
the eye on deck the backstay angle is reduced by as much as 6 inches, which
makes low wind tacks and gybes of the mainsail difficult. Especially so if you
use a small amount of backstay to create a better entry on the headsail for
sailing up wind. </P>
<P>The headstay plate -- This can be changed to the J24
hardware with minimal alterations (but to bend it with a hammer and vise
may weaken the plate). Several of the local Capris in the WYC fleet have
had a 6" L x 3/16" T x 1" W - SS chainplate welded to
the original tack plate and have 1 to 3 countersunk 3/8"
dia. screws and a reinforcement block on the inside with fender washers
and lock nuts. The total length of the chainplate addition is up to the owner
but 6 inches (with 2 holes) is typical. The rub-rail on the bow
point does not need to be removed; just slightly altered to accommodate the
chainplate thickness and width when installing it underneath. I use
a 1" chissle to pry the aluminum rail from the hull. The chissle
will stretch the aluminum nicely without breaking it. Just be gentle and be
sure you remove the mounting screws under the rubber (the most forward ones)
first.</P>
<P>One good thing about adding the chainplate in the bow -- it you
t-bone someone -- the damage to your bow will be significantly reduced -- just
ask the guys on Fore Sail who tapped Ham-It-Up! this year...</P>
<P>Happy sailing, <BR><BR>Mark Hammett<BR>Capri 25

need to be careful how much force you are putting into your boat. 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.

style="FONT-SIZE: 12pt">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><BR>-- <BR>Ken Reiff<BR>Email:
