130% genoa size

[johnsons185]

Hi All,
Anyone have the approx sizes for a 130% geona, i have had two quotes and both are of different size.
I thought there may be a standard size for the vega or does it vary as its not a strict one design

Scott,
Go to the files section on the Yahoo site and look at the Vega_Sail.jpg
It has detailed sail sizes for the original sail plan.
Hope this helps,

The use of percentage can be confusing. It all depends on how the genua is being cut. Normally percentage is used according to the J meassurement (Distance from the front stay at deck to front of mast). All depending on the cut of the genua, (low or high) it might have different meassurements.
The percentage can also be compared to area of front triangle. (forestay, mast and deck)
An examle is that the Genuas that Peter and I have are both being called 120% by their sailmakers. They have the same luff and leach, but mine is 1´(30cm) longer in the bottom. I think Peters is a 120% genua compared to J meassurement and mine is a 120 compared to fronttriangle area.
If using the J meassurement, mine would be a 125% genua.
Confusing, yes, but it doesnt matter when you´re out there and you like your genua.

What are the measurements that the two sailmakers have given you (luff, leach, bottom and area) ?
