Title: How balanced are you pointing
Post by: Harrier on June 17, 2013, 06:38:26 PM
So recently there was a post "How high is your 19 pointing".
As a result of this post I took sometime experimenting on my 27, to find out high I could point. 
Turns out it depends on what tack I'm on.  On a starboard tack, I can comfortably pointing up to 30 degrees.  However on a port tack, the sail begins to stall at around 55 degrees.  I originally thought it must have something to do with the current, but I've now repeated my findings on a couple different days, and in different conditions.  I should note that on all these occasions I've only been using the genoa.  All rigging is balanced from side to side, at least as far as I can tell.  Only visual difference I see is that the sail cover (roller furler) is on different sides of the sail for each tack. 
Besides the obvious conclusion that I am just a poor sailor  ;D , anyone have any ideas as to what could be causing this?

How clean is the boat's bottom (and rudder)? I've heard of boats getting more growth on one side than the other that sailed differently depending on which tack they were on.

Is there any tension on the furling line that is keeping the foil from rotating into the wind on one tack but not the other?

How is the weight distribution from port to starboard? Does she float level if you look at the stern from a distance?

This is probably a silly one, but do you have the genoa cars set at the same place on both sides?

Does it count if I fell asleep on my CP-19, Comfort & Joy while sailing with everything 'in balance' and cleated down?
I sailed at least a dozen miles while sawing wood in the cockpit all snuggled into the throw cushion on the settee.
In fact I missed a course correction to Sturgeon Bay from south of Cedar Creek. Opps! Don't do that.

Harrier adds; "Anything said in Latin, sounds profound." or --> Quidquid latine dictum sit altum videtur. Anyone remember how to speak 'Pig Latin'?

Skip, I'll admit, I'm at a loss.... ;D

Nate, thanks for the ideas.  Cars are at the same spot.   
Boat just went in the water a month ago, and the hull was clean.
I'll double check the furling line/drum, but I think that is ok also.

Weight balance could be a player,  this spring when I was rigging up the mast, I tried to get the boat balanced as best I could to ensure the mast was plum to the deck.  I used the "tilt-o-meter", not the highest quality instrument, to level the boat.  Surprisingly I had to move alot of stuff to the starboard side of the boat.   
Can weight balance have that much of an effect?  Should I have rigged the mast with the boat in its natural position rather than leveling prior too?

Thanks!

I point at 40 degrees on each tack.   Have you sent a measuring tape up the rig to check all your standing rigging lengths?

Maybe your wind vane is reading 10 degrees off and you really are balanced.

and skip, anything said in pig-latin sounds like you are trying to hide it from the kids

Sounds like some more 'sperimenting is in order.

She looks like quite the lady.  That is a great photo and it really speaks volumes.  She's got a similar look to my mom, who would flip some eggs and hash for all my goofball teenage buddies after chasing them out of the house for having mud on their shoes. 

At the risk of diverting this thread into a totally unpredictable direction, I am kinda hoping there is a good story or two to go along with this photo.

So as suggested I check the calibration of my wind instrument.  Motored dead into the wind but found the instrument was reading ~10 degrees off.  Figured out how to calibrate it, and wah-lah problem solved. 
While I was learning how to calibrate the wind instrument, it got me to wondering about my speed calibration. 
Turns out it was also off by ~1.5 knots.  And all this time I just thought I was a really bad sailor  ;D
Amazing what you learn when you read the users manuals! 
I even found out that my depth gage reads the water temp, which by the way broke a balmy 70 degrees last weekend.  Nice touch!

That Polaroid of my mom sitting in her uncle's panel Ford Model AA truck was taken on Drummond Island near the North Channel.
Mom's uncle was the postmaster and general store keep on the Island and our family would sail our schooner, Auf Wiedersehen
up there from Chicago for a visit.

Here she is somewhere in the North Channel.
