Tom,

 

This is a case of flat is fast. My rule of thumb for Catalina's has always been 
you sail with windward side of the companion way level. If it goes beyond level 
you need to depower sail. (Of course if you want a dream boat to sail you get a 
C270, Wing Tip holds course so well with a locked rudder her autohelm is an 
annoyance.)

 

C270 plug aside, what kind of backstay adjuster do you have? 

 

The instructions for rig tuning always reads the same but you don't have to get 
there in the same manner. I like standing the mast very vertical and hauling 
the tip back with an aggressive back stay adjuster. I know it sounds like if 
you’re doing the same think why bother but there's some subtle differences in 
results. The boat is always sailing in apparent wind not true wind so the wind 
is always strongest going to weather. That means sails need to be trimmed 
flatter going to weather every time and fuller off the wind. While the outhaul 
and Cunningham play a big role using the backstay adjuster to curve the mast 
will flatten the mid portion of the sail as it moves the center of effort 
forward. It also brings the tip back and improves the pointing angle, as does 
the prescribed 6" inch mast rake you mentioned. We had one race boat so dialed 
we could pull in lee helm. I'll agree that's undesirable but you pass through 
neutral helm on the way to lee and that is desirable.

 

BTW this was a C22 and Catalina Direct sells reinforced tiller handle plates 
because the stock plates get bent so often, but it is really a sail trim issue 
and once you get it you wonder why you ever needed the stiffer side plates. 

 

Even with that particular race boat we sailed her relatively flat, even though 
we could set the helm to neutral, because setting sails to put the winches 
awash is slow. Although washing the winches is a good way to temper new race 
crew. 

 

As you know Wing Tip has a trailer and I raise and lower the mast by myself. 
One of the key modifications I made to Wing Tip was to change out her split 
bridle backstay adjuster for a 16:1 double cascade adjuster. Besides getting 
better sail control this allow me to let out past normal to let the forestay go 
limp when I'm rigging the boat. This lets me leave the forestay's length 
permanently set. Since the turnbuckle is under a furler drum it is a big 
timesaver when it comes to getting tuned up again. I put a stopper knot in the 
line to the blocks that has to be removed to fully relax the backstay so this 
doesn't happen under load and a sharpie band on the line where the knot belongs.

  All ... 

  More info ......... 

  1. I don't think it's sail trim. On the wind in pretty steady conditions such 
that we can discount gusts for sake of discussion, at a measured 15 degrees of 
heel; a relatively new 135 up, led, and sheeted, and the boat pointing 
correctly, such that all three sets of telltails are laying flat or 
occasionally ticking to windward (top first); and a main with a boom positioned 
on the centerline and the sheet tensioned such that the telltails on the 
battons are all flying straight out (or the top one falling off occasionally), 
I have to use arm strength, not "two fingers", to keep the boat from turning 
into the wind. I couldn't tell you how many degrees of rudder I have to apply, 
but my point is that it is taking constant pressure to hold the boat on course, 
which is NOT how some of you have described a properly tuned rig at 15 degrees 
of heel. 

  2. Each fall, I have to take the tension off the rig when it comes out of the 
water (lift requires me to remove the forestay), so I have to retune each 
spring. And I like the tension off the rig in the winter anyway. Per 
recommendations on this list when I first got the boat, I started by 
positioning the mast such that the main halyard intersected the boom about six 
inches back from the mast, and then tensioning the rig from there. In an effort 
to reduce my weather helm, I've been moving the mast top forward an inch at a 
time until, as I said before, the mast is standing straight up ... the main 
halyard intersects the boom right at the base of the mast. Thus I have moved 
the center of effort pretty far forward. The problem is somewhat better but not 
gone. 

  So ................. when I read a respected sailer, Judy, talks about two 
fingers on San Francisco Bay, and I read on this board and others about boats 
sailing merrily along being gently guided by their captains, I get frustrated. 
Yes, I can deal with the problem by dumping the travellor or otherwise triming 
to move the center of effort forward, but it seems to me that I ought to be 
able to tune the boat such that in 10-12 with a 135/main she is properly 
balanced without doing so. Maybe I'm just being unrealistic, but I don't think 
so. I've trimed and helmed other boats in such conditions that have had an 
almost neutral helm. 

  Thus, my question to Judy. Hope all that helps.

  Good point!  We need to know as the wind builds do you need to push the 
tiller up wind or downwind to keep her tracking?  If you release the tiller 
which direction does the boat go, head into the wind or turn to run off the 
wind?  The correction for helm is mast rake and a little goes a long way on a 
well designed boat.  Did you make any changes to the mast position or has it 
always been the same and the handling as wind increases the same?

  …But you say you’re dragging a tiller through the water, which seems to me 
you’re fighting a lee helm and turning the rudder to keep from bearing off, not 
a weather helm—and if that’s the case, and your mast is vertical, you’ve moved 
your center of effort forward instead of aft where you want it.
