Many sites can give you an online quote. BaconSails.com is a good one to check. They use a loft in Sri Lanka, but shipping goes to them first for a quality check, which gives you a US contact for quality issues. As a result their pricing is fairly competitive, but probably not the absolute lowest. In other words, a good benchmark.

Hey,

How long is a string?

What kind of jib do you want? Basic dacron? The latest high tech laminate? Radial, cross cut, etc.

Perhaps call a local sailmaker a talk to him? Or look on line at the big places?

Good luck,
Barry

I'd budget $2500

You can find this and more via web search.

But, if you call within the next 20 minutes.....

135% vs 150%

Many times in very light winds a sail will experience a ''separation'' of air flow due to its too full shape. This is not a stagnation or stall as commonly found when incorrectly setting the angle of attack. The separation will show sometimes as a recirculating ''reverse flow''. For ultra light winds and once ''up to speed'' it sometimes will benefit to flatten the sails to prevent such an airflow separation. The larger the draft and the larger sail will become more unstable for flow attachement under these. Lightweight Tell-tales mounted all along the sail will show such separation. Tell-tales made from mini-audio cassette tape will work best, as tales made from ripstop may be too heavy in ultralight condition. When flow separation conditions are evident, this is time to FLATTEN a sail.

Sails work within a range of wind strengths. A 150 is a light air sail, but there has to be enough wind to lift the weight of the sailcloth and hold it in the shape that drives the boat. If it''s hanging limp, and if you have enough crew to move them forward and to one side and heel the boat about 8-10 deg., gravity will help the sails hang in that shape. By moving crew forward, you will also reduce the boat''s wetted surface, reducing drag.

More often than not, you won''t have enough crew members to heel a ballasted boat to that extent in light air, so your other alternative is to raise a sail made of lighter weight sailcloth and lighter weight sheets. It takes less wind power to lift and hold the shape of a sail made of lighter weight sailcloth.

Also, in extremely light air, the wind isn''t strong enough to lift your tell tales, and that makes it difficult to know when the wind has shifted in its direction. Occasionally I''ve been on a beam reach and had the wind die, and sat there with limp sails waiting for the wind to come back, only to realize that there is air movement, but it is now coming from dead astern, but it is so light that it couldn''t lift the sailcloth or the tell tales. When the wind is that light, pay extra attention to the feel of the air on your skin. Sometimes (not always) you can feel it. You have to look everywhere for clues. The surface of the water can provide visible clues to the wind direction. It helps to light a cigarette or cigar, or anything that produces a smoke trail, because the smoke will react to even the slightest amount of air movement. Once you know the direction of the air movement, you have to either re-trim the sails for that direction, or alter your course to the course that will get you moving again and achieve the best velocity toward your objective, and then trim your sails accordingly.

Hello,

I don''t know why the 150 doesn''t work well in light air. Maybe the sail is too heavy? It seems to just sort of hang in light air and I can''t get any shape to it. I''ll have to check the sheets, I haven''t thought of the size issue.

Thanks,
Barry

the asymmetrical would be good for broad reaches and downwind sailing, but you have to turn around sometime.....

Why doesn''t your 150% work well in winds less than 5kts?? With a 100% it will be worse. How heavy are your sheets?? The reason I ask is that when I bought my O"day 28, the genoa sheets were WAY TOO BIG for the boat. They were heavy (I''m guessing larger than 1/2 in) and they pulled my sail down in light air. I went to 3/8 in. sheets and there was a HUGE difference in sail trim in light air!!!

135% vs 150%

Hello,

I can''t help you decide, but I can offer some comments, and I also have a question.

This year the sound had light winds all summer and early spring. There was little or no wind in August or September. Then in October it was blowing 15-20 (or more) just about every day.
So the 150 wouldn''t really be good in the light wind, and it would not be good in the heavy wind either.

I had a 150 on my boat (Newport 28) that I put on in June when I bought the boat. It is in good shape, but didn''t work great in winds less than 5 kts, or in winds more than 15 kts.

I started experimenting with an asymmetric spinnaker and ATN chute. That sail is a lot of fun to fly, and works great in light air.

I''m starting to think that I might be better off with a 100& jib for the headsail. That would work for the heavy winds, and to just use the cruising chute for the light winds.

Does that make any sense, or am I better off with a 135%, or what?

I don''t race, just daysail and some weekends.

Thanks,
Barry

There is no single sail that is going to give satisfactory performance in all wind conditions. Eventually you''re going to need a second sail if you want to cover a wide range of wind conditions. In your situation, I would suggest a 135% headsail, which can be used in a wide range of winds, except for light air. For those light-air days, when a 135 is just not enough, I suggest a drifter. If you add the cost of a drifter to your boat loan, it won''t add much to the payments, especially if you can find a bargain on a used sail, and, when the wind dies and your sails are slatting next summer, you''ll be glad you did. If you try to get by with only one sail for all conditions, your new boat will suffer in either light or heavy air, and you''ll miss out on some good sailing.
