I was having an issue with too much furling line on our boom furler and
schaefer sent me a replacement furling line with the cover removed for
about 20'. (not for free but...) It really helped with the bulk on the
spool

What about a high tech line that is smaller than 5/16 diameter for the
first 30 feet or so and then larger diameter for the final amount
where your hands work the rope. Would that not fit better inside the
furling drum?

Seems about right. And I too will unload the sail before furling or
reefing so there isn't the full force of the sail working against the
furler.
Calculations of the load of the sail transferred to the furling line
would be difficult given sail size, wind speed, wind angle, friction
in bearings in the furler, sail condition, and sheeting would all play
into the equation. More of a sailmaker question I would think...
Or if one had a load cell that could be hooked up to the furling line
for field testing.

Chuck,
I cannot pull the furling line when it is loaded. I know that
people try doing that with a winch, but from what I know it is not
what furler manufacturers recommend. I furl only when the genoa is
slacked (usually a bit down wind, during a tack, or when sheets
slacked if little wind).
In order to split this hair... Assuming that the radius of the
sail wrapped around extrusion is the same as the radius on the
drum, the force would be equal to what the sheet is pulling. I
think that one might assume that the leverage is 2:1 (the drum
radius is double of the sail radius), so the force is half. I am
not sure how safe is that assumption.

Marek,
The tensile strength of 5/16” XLE polyester double braid is
roughly 3600 lbs. Even if one were to assume a 5:1 ratio to
develop a “safe working Load” you’d still be looking at 720lbs.
I can’t imagine that there would be that much pressure against the
drum..you certainly wouldn’t be able to pull the line if it were
loaded that heavily.

Anyone calculated what should be the working load strength for the
furling line? It does not count, if you don’t ever use it for
reefing, but what if you do?
One could probably run some calculations (e.g. based on the
working load on the sheet and the ratio of the diameter of the
furling drum and the sailed furled on the extrusion), but if there
is a ready-made solution, I would be interested.
thanks

+1 on Cajun Rope. Very reasonable pricing. Also check with R&W
Rope in Massachusetts www.rwrope.com <http://www.rwrope.com> and
search under Novabraid XLE as that is the same rope sold by Cajun
(made by Novabraid from Nova Scotia). R&W does free US shipping
for orders over $30. Jamestown Distributors is also currently
having a sale on the same line
https://www.jamestowndistributors.com/userportal/show_product.do?pid=54238&familyName=Novabraid+XLE+Polyester+Double+Braid+per+Foot
The line used on my boat with a Furlex furler is 5/16” (8mm).
3/8” would be too large diameter and take up too much room on the
drum and I only have a 135% jib on my boat.
