Monolines have only one point of support on the boom. Once you set them in a certain place on the boom, make sure it is the right one, otherwise the sail will not feel balanced. They are much easier to move along the boom compared to duolines.
We have two kind of tube stiffness – sofr (blue colour) and hard (black or white tube colour – depending on availability in our stock).
