More data from a past note regarding Ursa Minor's mainsail:

>Here are the sizes forthe three sails resulting from two reefs:
> foot luff
> full main 94" 230"
> 1st reef 81" 200"
> 2nd reef 65" 160"
>Some are measurements, some calculated therefrom.
>
>This places the second reef 70" up the luff (the first came from the

> 1st reef 75%
> 2nd reef 48%

Hope this helps.
