Will you need a small (" S "),
medium (" M ")
or large (" L ") drum?
Furling a
genoa for storing it will requires a certain amount of turns
around the foil, this amount depending on the " LP " length,
(please see drawing), but also depending on the way you are
going to use your system - i.e. how tight you are going to furl
your sail - also on luff extrusions diameter, and on sail cloth
weight to a certain extend. When your sail will be fully deployed,
the drum should contain at least the same number of turns as
the ones of the fully furled sail (and even a few extras in
reality) : this is the drum capacity. |
| For
a given sail and a given drum, the only way to increase the
drum capacity will be to use a thinner furling line. Under a
certain diameter the line will harm your hands, as in the same
time the tension in the furling line diameter will increase
when you will want to reef your sail, with added stretch to
the furling line, making sail control more difficult. |
| Note
: do not select a model with a drum capacity that is too much
on the edge, as drum overfill will happen in case you deploy
your sail without a strict control (by adding much drag on the
line during sail deployment). |
DRUM CAPACITY WITH DIFFERENT PROFURL MODELS AND FURLING LINE DIAMETERS.
LP= length of the sail to be furled. These datas are average and for
information purpose only. They depend on how tight the sail will be
furled and on sailcloth weight.
