Go to: Mainsheet Options \| Splicing Services

Mauri Pro Sailing offers you an easy way to find out the length of your mainsheet.

Select your boat from the drop down menu to obtain your E dimension (boom length). Find the mainsheet setting you have and multiply "E" by the corresponding factor.

End Boom Mainsheet Length
For 4:1 mainsheets = E x 5.6
For 6:1 mainsheets = E x 8.4

Mid Boom Mainsheet Length
For 4:1 mainsheets = E x 4.3
For 6:1 mainsheets = E x 5.7
