I am attaching photo of Genoa swivel with blue halyard. Is the some thing for main sail? So I do not need to order any eye splice on the sail side. Just use the knot on this side and that is it? Will this change the length that I will order? As per specification the halyard length is 17,2 m. Thank you. -- Slavko SM 2000 #279 Bonne Anse in Croatia
