Jib Conversion

[Jesse]

One of these days I will probably want to get a furler. Is it possible to convert a hanked on jib to a furling jib?

Yes it is possible but it depends on a lot of factors. To start with there are grommets in the luff of your sail. These are not easily removable. The luff tape you will want to install will have to be sewn over this same area so you will most likely need to cut off the width of the luff that contains the luff rope and grommets. You can then either sew a replacement slice of material to the sail followed by the luff tape or sew the luff tape to the edge you just created. If you don't replace the original geometry of the sail the center of effort might move a little forward and you might lose the shape. Other work will require a new tack and head ring and adding a suncover. There is a lot of work in what you are proposing and I'd suggest you look for a used sail and keep this one as a spare. You should get a quote for the work you want done and then quote a new sail. What size boat is it? The type of furler defines the luff option for the sail.dave

No problem

Sewing a luff tape onto hanked sail is no problem for a competent sail loft. Shouldn't cost too much. It is easier to convert a hanked luff to tape than vice-versa. If you plan to use the old sail for less than one season you might not need to invest in a UV cover. Other wise, spread your cost by buying the furling system one season and equipping your existing sail with the appropriate luff tape and a UV cover, then when your pocketbook is replentished, purchase the best RF headsail you can afford.

Roller Furler Conversions

Jesse, Converting a hank-on jib to fit a new roller furler is a fairly straightforward job and we do these on a regular basis in our loft. You will have to first install the furler on the boat and then provide the following information to your local sailmaker. 1. Type and model of Furling Unit. This is required to ensure that the correct size Luff Tape is installed on the sail.2.Max Luff Length. Attach a measuring tape to the shackle where the head of the sail hooks on to the head swivel. Raise the genoa halyard until it stops at the top. Measure down to the shackle on top of the furling drum at the bottom of the headfoil. Your sailmaker will make a standard deduction from this number and then cut the luff down to the proper length. Usually this will not noticably alter size or performance. If your sail is shorter than this measurement you will need to install a pennant.3.Cover Side and Color: Depending on whether your drum furls clockwise or counter-clockwise the UV Sunshield will be installed on the port or the starboard side of the sail. UV Covers can be made out of white UV Dacron or any shade of an acrylic material such as Sunbrella. This primarily a matter of aesthetics. 4. Luff Pad ? A Foam Luff pad is an option that should be considered, especially if converting a genoa with an overlap of 135% or more. I would recommend one if you plan to use the furler as a reefing system. The pad helps keep the sail flat as is is furled.Hint: Call a couple of the dependable lofts in your area as prices can vary. Bill Colombo, Doyle SF
