Question about boats with two rolling furlers.

Hello. When looking at sailing magazines, the bigger boats in ads will often have two rolling furlers for head sails. Sometimes the foremost headsail is out and I'm trying to figure out how one would change tacks in that situation. The sail would have to pass in front of the rolling furler that is behind it and it seems to me that it would be next to impossible without rolling the sail up and then unrolling it again on the other side. Are the sails used only when you know you will be on the same tack for a long period of time and therefor not have to change tacks often?

Thanks,
Owen

Re: Question about boats with two rolling furlers.

There are two different setups that you'll see in these photos.

The common and classic one would be a cutter rig. In this case there is a jib or genoa forward and a staysail that is multiple feet behind it. To tack those the jib or genoa has to be skirted around the staysail. It's annoying in tight quarters, so this configuration is more common on large cruising boats. A friend has a beautiful cutter that we've "raced" in the local beer can race, and we have to take the course really wide because the tacks take us longer.

A modern alternative is to have a Code 0 or asymmetrical spinnaker on a forward furler and the genoa on the rear furler. Since the Code 0/Asym are only used off the wind they aren't tacked, only jybed.

Re: Question about boats with two rolling furlers.

Alex,

Code Zero's are upwind (about 40 degrees apparent) and reaching (up to 90 degrees) asymmetric spinnakers they are not off wind sails. With these set ups, the intent is to roll up the sail, tack the boat, then unroll it on the new side.

They are primarily intended for off shore sailing, when you won't be short tacking the boat.

Re: Question about boats with two rolling furlers.

Stumble, thanks for that idea. My "jib" is actually more like a genoa. It's pretty big, and tacking it can be a real pain. It seems to get hung up fairly often. If I partially furl it first, that might help.

Re: Question about boats with two rolling furlers.

There's also the solent rig, with a genny on the headstay and a smaller headsail on the inner stay (quite close ).. this allows easy and complete transition from large to small headsail without resorting to partially rolled sails. In this case there's nothing for it but to roll up the larger sail in order to tack.. but that's not required for the inner sail. Sometimes the inner stay is removable/stowable to help out on that score.

I think it's mosty intended as a cruising rig where frequent tacking would not be necessarily expected. Bob Perry's Sagas are rigged like that.

Jim, I think you'll tire of rolling and unrolling.. problems tacking are usually due to technique, or presence of a baby stay.. much easier to install a larger diameter sleeve (3-4 feet of 2" PVC pipe eg) over the babystay to facilitate sliding by than to work the furler on every tack...

Re: Question about boats with two rolling furlers.

Trigger: Furling sails use a luff tape instead of hanks. If your current jib isn't in near new condition you'll find that you'll likely want to just replace the whole thing. The cost of changing the hanks to a luff tape and adding a UV cover or sock is about one third to half the cost of a new sail.

On a 24' boat I'd suggest using the hank-on sails for a while. They work well and are pretty easy to handle on a smaller boat.

Stumble: Thanks for the correction on the Code0.

Trigger.. your current setup has 'clips' called 'hanks'... the front guide cable is called the forestay.

Here's a shot of how a luff tape jib slides into the rolling extrusion's slot.. as you can see the forestay is covered with the furling apparatus, the sail slides into the groove and is hoisted up.. the black swivel allows you to roll up the sail without wrapping the halyard around everything.



There are other furling setups that might work well on your boat and be much less expensive. We had a 24 footer with the stay itself swiveling on a furling drum, using a zipper luff sail and internal halyard. Works well for smaller boats as long as all you want is a furler.. such a setup is not intended to be used to reef the headsail.
