Sorry Judy, I should have mentioned I had emailed them and that is where I received my information. It took me three attempts to post the reply so it became more abbreviated each time...I know it's hard to believe that was the abbreviated version.Judy B wrote: BWY is highly respected for their honesty and good customer service.

Their website says 5.0 oz dacron and 5.5 oz dacron.
Their website doesn't mention "High Modulus" anywhere.
In fact, their website doesn't even mention Challenge anywhere.
THERE IS NO SUCH THING AS 5 OZ OR 5.5 OZ CHALLENGE HIGH MODULUS CLOTH.
Challenge 5.53 has 250 x 300 dernier threads in the weave. It does not weigh 5.53 oz
Challenge 6.03 has 250 x 400 dernier threads in the weave. It does not weigh 6.03 oz
They both weigh exactly the same. 6 oz.
The difference in thread diameter are offset by threads per inch and density of weave, to arrive at the final weight.
Thanks Todd for clarifying. Good to know also that there isn't much point in asking for reviews if these sails are new for 2015.bwytodd wrote:Sorry, I should add for clarity, what we refer to as HIgh Modulus 5 and 5.5 OZ are really 4.93 and 5.53, I guess rounding for simplicity actually caused more confusion than it eliminated! Also, many of you who have commented that Doyle sails that you have purchased from us over the years do not appear to use this high quality cloth are correct, the older sails were the straight factory sails, the new sails are totally different and greatly improved.
Judy, your website advises you use Challenge 6.03 Low Aspect, High Modulus Dacron on your 120X jib sail but I don't see this product on the Challenge Sailcloth Website.

When they refer to Low Aspect or High Aspect, I'm assuming they are referring to the sail design? On an airplane, a wing with a high aspect ratio is long and skinny, such as a glider wing. Same thing with boat sails? Also, what are AP-1, AP-2, AP-3 sails they refer to in their general usage chart? Would this be like an All Purpose #1 - 3 Jib? They also refer to LT-1, MD-1, MD-2, HV-1....I'm guessing Light Med & heavy, does this refer to suitable wind speeds that I'm guessing would be utilized in this fashion more in a race environment? I realize these tables are probably a VERY loose guide.
The more I learn, the less I realize I know.
Cheers,
John
