Or measure the line that came off the drum to begin with… As was previously mentioned, some folks will remove the core of the rope that sits on the drum to avoid extra bulk. My only concern with that approach is when someone uses a winch to furl their jib. Removing the core from a double braid rope will reduce tensile strength by nearly 75%. I’m more inclined to use a single braided rope such as NER Regatta Braid, Novabraid Sprint, or Samson Control DPX which will flatten out when spooled on a drum, but will retain 100% of tensile strength.

Be sure you have enough line to wrap it around a winch and tail it.

Divide by 2 and multiply by pi (3.1415). That will give you the "circumference" or length of rope for one wrap around the drum. Yes it will change as the rope unwinds from the drum but for the sake of argument, let's use the max circumference as a constant. Measure the distance from the drum to the furling line cleat, taking into account any guide blocks or rollers that the rope needs to pass through. Now furl the jib taking care to count the number of turns on the furler from fully deployed to fully furled. So the length calculation will be: Circumference of rope on drum times the number of furler turns plus distance of drum to cleat plus 7-10' or so extra rope to allow line to be handled in different spots of the cockpit. Depending on conditions such as wind and jib sheet tension while furling, my jib can be furled either really tight or rather loose and sloppy. Tight almost always requires extra turns on the furler.

The marker the diameter of the drum, the longer the circumference and thus the longer the line required for one rotation - but the circumference of a roll of sail will be potentially very different. -- Jonathan Indigo C&C 35III SOUTHPORT CT > On Jun 12, 2016, at 07:01, Josh Muckley via CnC-List <[email protected] > <mailto:[email protected]> > wrote: > > plus the foot length (24') _______________________________________________ This list is supported by the generous donations of our members.
