Scott,
after all the hard work you have done to get that rig working, I think both you and the sail deserve to finish the job:

To get rid of all those diagonal creases, I suggest you fit Hong Kong parrels and a running throat parrel.

In addition, to stop that lowest leech from fluttering, an elastic tack line, tied to the boom so it looks like a kicking strap, should be fitted. When the sail is fully up, the TL should have some stretch in it.

Good luck  -  remember that a sail has only been finished when it has been correctly rigged.

PS: Here is how it should look. The HK parrels do most of the job, but by pulling a bit on the THP, the load on the HKPs is much reduced. No bend in the battens.

PPS:
The diagonal creases in your sail are not just cosmetic. They remove a good deal of camber, so I think you lose some drive and suffer added drag instead.
Going upwind and tacking is all about improving the lift to drag ratio.

Conditions were right to have the full sail up and be out on the 'big lake' on Saturday. I was able to record a video. Please ignore the mess of lines and dirty boat.

On the starboard tack on a close reach the sail balances the boat just about perfectly without me touching anything. On the port tack there just a little bit of weather helm. It is barely noticeable but it is enough that the boat will tack through if I don't keep my hand on the tiller.

The video shows me tacking to change from the starboard to port tack. It is much more difficult to 'make' this tack. I have 'missed' and got blown back onto the starboard tack several times. (It seems to happen most often when people on shore can see me). Tacking the other direction is very easy. I have never had a problem.

I am trying to decide if this is a problem that I can fix, or if this is just the way it is.

I agree with the other comments that lee helm is not unusual in very light airs, with junk rig.  Also, of course, junk rig is much more amenable to adjustments made after the event, than a sail sliding up a track or hanked to a forestay.

Hi Annie,

Thank you for the response. Please do not go out in the rain just to get me a photo. When the weather is better and, if you have time, I would like to see some of the details.

I am always amazed to find that there is a proper nautical term for every part of a sailboat. I spent some time looking at images of 'mast bands' used on traditional western sailing rigs. I had no idea this piece had a name.

On Saturday the weather was just about perfect for day sailing on Lake Michigan. The wind was about 9 knots from the south with smooth water and clear weather. This is perfect for going out on a reach, as far as you care to go, and then sailing right back on the reciprocal tack.

In these conditions I experienced neutral helm and just a slight bit of pleasant weather helm. It was a good day sailing and I am very happy with the rig.

To be clear I am absolutely happy that I converted to a Junk Rig. It is so much better for single handed sailing than a mainsail on a track and a hanked-on foresail.

In no particular order this is what I am enjoying:

- If I need to drop the sail and depower the rig quickly all I have to do it let the halyard go from the rope clutch. This is awesome.

- If I need just a little bit of sail to get moving again in the harbor it is just as easy to pull one or two panels back up and sail slowly. The precise maneuvering I can do under sail is great.

- The sail is so quiet. Letting the sail luff makes a very soft and pleasant sound. To me it sounds like fresh, dry snow under my boots on a calm winter night. This is so much different than a triangular Dacron sail flogging in the wind.

- I can round the boat up into the wind (in irons) to stop for a minute without any stressful sail noise. This has already been useful several times.

- I have one big yellow sail.

- Even when things did not go exactly right hoisting the sail I never had to leave the cockpit. I am sure I am much safer. It is very unlikely that I will fall on to the deck or off of the boat.

- Self tacking! Working my way up wind is fun. No sail trimming required. I just sail back and forth using the tiller. It is so easy and enjoyable.

Scott.

I am a little concerned about the helm balance. With the right wind speed and the right angle into the wind it is perfectly balanced. This is huge change from my South Coast 23 where I had to pull against the weather helm constantly. But in light air the boat has lee helm

hi scott

sitting on the lee side is very convenient in light winds – and it reduces the lee helm a lot on small boats.
