along with my boat came a couple of unmarked sails that I am not sure what they would be.
One measures: 28ft6in luff and 10ft foot, has batten pockets and a hand written marking “mega” on all three corners.
The other measures: 35ft luff and 17ft foot.
One other question, what determine an Olson´s sail number and how do I read an Olson HIN?
Thank you, have a great weekend

Sounds like the first sail is a #4 (or smaller?) in that it’s around 9′ short of max hoist and the foot is just under 2 feet less than J. The second sail looks like a #2 – almost full hoist with just over 5′ of overlap aft of the mast.
If I recall correctly, the 6th, 7th and 8th digits of the HIN correspond to the build number and correspond with the class number. Your actual sail number will depend on whether you’re racing PHRF in which case you’ll be given a different number.
The first 3 digits of the HIN are the manufacturer’s id, the next five are the serial number and the final four are the date of manufacture.February 16, 2014 at 2:55 am #3253

Thanks for your input.
What numbers would then be a 155, a 125 and a 95% sail?
Thanks for the HIN decodingFebruary 16, 2014 at 4:51 pm #3256
Those are percentages of “J”. “J” on an Olson is 11.8 ft. Multiply the numbers times 11.8 for the LP measurement of the sail. LP is the max length from the clew to the luff. This is known as the amount of overlap to the rig. Actual % is LP divided by 11.8.February 16, 2014 at 4:54 pm #3257
A 155% is a number 1 sail (usually light material). 150 is an all purpose #1. 147 is a heavy one. 125-130 is a # two. 95-100 is a three. 85 is a 4. Anything less is storm.February 19, 2014 at 2:32 am #3258
What is the wind range you would use each sail?
This is a question by someone who is used to roller reefing on cruisers…. So new to this sail change and racing thing…

Lt #1 to 6 knts true; heavy #1 6 to 14 true; I go to the #3 @ 20+ apparent ws.
Waves…keep the #1’s longer and move lead car aft to spill the top some.
This will invite MANY opinions on sail selection. One opinion sure to arrive is the need, if any, for a #2. I’ve never used one and don’t hear of many that do. I suppose if you were short on crew, it could take over after the light #1.February 22, 2014 at 2:38 pm #3263
#2’s are absolute weapons. Old School sailed with AP#1 (which was pretty light), 2, and 3. In 14-18, a well sailed boat with a #2 will kill any boat with only #1 or #3.February 22, 2014 at 3:06 pm #3264
Hi Old School,
Do you think your #2 experience holds for solo sailing?
I feel that using #1 and #3 sailing solo would be easier with fewer sail changes… Makes sense?February 22, 2014 at 3:20 pm #3266
I actually think that for solo, it would make more sense to have the #2. The boats do not take much power to move. Once I raced against O’Naturel. He was DH, I had five. I carried the #1 in 10 knots, he carried the #3. We were quicker, but not as much as you might think!
An excellent option for SH sailing is to ditch the #1 altogether. Carry the #2 as your primary upwind sail, and take the rating credit! Probably worth 6 seconds. I think that when SH, the only time you would see an appreciable difference between a 1 and a 2 is in 3-4 knots of breeze.
#2’s take less energy to tack and stow. This is a big consideration when SH.February 22, 2014 at 10:06 pm #3269
Thanks Old School, your advice makes plenty of sense… I like it… less sail to tack is always good…
