When I bought my Sandpiper it came with a DRS or Genneker. I know these are brand names so I'm still trying to figure out what it is.Anyway I had the sail pulled out the other day at work to look at it (I'm thinking of selling it). While lookin at the sail opened up I though it looked to big for our pipers. I measured the luff and came up with 22'-8". I think this is to large. Does anyone on the forum have an assymetrical spinnaker that they can measure the luff, leech & foot on? I would like to know if this is for our boats or a larger one. The PO of my boat never flew this sail and it came with the boat when he bought it. Patrick "Barefoot"

To put the size of that sail into perspective, if you run a straight line from the pin at the bow where the forestay attaches to the underside of the mast head, it is approx. 23'-7".

Fred,I know this sail is for light air, but would you actually want to attach the sail way up there? Since our rigs are a fractional style, would the mast not be supported and possibly break while flying this sail.

I was not suggesting that you flying that sail from the mast head.
I gave you that dimension only to illustrate the large(over)size of the sail 
But on that subject my Luna 24, which is also a fractional rig but with a backstay, is rigged to fly a spinnaker from the masthead.

The DRS is meant to be flown from the masthead. I have two types of cruising friends; those who love having a DRS and those that don't have them but want to.There have been some great developments in cruising rigs over the last few years. Roller furling, slab reefing, cockpit centred control lines make sailing so much easier and comfortable. Shortwave's furling and reefing makes her a joy to sail as a couple. We can power up or down quickly. The only trade-off at this point is when running or reaching in light air. The slightly smaller jib means Shortwave isn't going at her maximum hull speed. (You can tell because we don't get that delightful gurgling sound when she's churning through the water.) A DRS would solve that loss of speed. So Patrick; if you're thinking of of selling your DRS, please let us know. We'd do some serious rationalizing for such a sail. (Lets see...Kids university education or a DRS; it's a tough choice.) How much you use the sail depends on the type of sailing you do. We usually spend half of our typical cruising day running down the the east shore of our lake. In the late afternoon, the low sun turns that rocky granite shore and pine forests a beautiful golden hue as the day's breeze lightens. A DRS would be marvellous addition to our cruising equipment. The trade-off is you have another bag in the cabin which as any of you who have cruised know is a loss of precious interior space. D'Arcy, Shortwave

Patrick, do you have a launching sock for the assym? What are the colours/colour?
Count me in, as one who is very much interested in getting an assymetrical spinnaker. Just email me!
That's if D'Arcy passes it by  Eric

I wonder if DRS launching techniques have changed over time? On small boats under 24 feet we used to go forward with a spinnaker turtle, attach sheets and halyards, then launch. Not only was a slow process it was scary in rough weather being up on the bow. It also slowed the boat down.We now launch from the main hatch. The chute goes up in the lee of the mainsail and is pulled forward. I think you could do the same with a DRS. As far as I can see, the only modification you would need is that the tack line be long enough. It would be controlled from the cockpit. To take down the DRS you would let off the tack line and pull in the leeward sheet. The system would be similar to an asymetricaI spinnaker and I think would be a lot easier to use than going forward. Any comments? D'Arcy, Shortwave

D'Arcy, you are talking as if there is a difference between a DRS and an assymetrical spinnaker. I thought they were relativly the same thing  . Can you briefly describe the differences between the two? Are they both used for sailing off the wind?Thanks for the clarification!

Genneker, we have one of these sails. I don't think it's ever been used. It came with the boat. We brought it to the rendezvous with us hoping we would have time to set it with the help of the real sailors in attendance. We ran out of time and our stay came apart. Mine is in a sock coloured white with 2 shades of blue.
Would anyone have a photo to show the rigging? I would like to use it at the next rendezvous.

You're right Eric, they are all quite similar. Or perhaps variations of a theme. A true asymetrical spinnaker would be attached to a pole that slides out like a bowsprit well beyond the bow. I think they would also be larger in size than a DRS.A DRS usually attaches to the bow or a short line off the bow. It's more of a cruising sail because it takes less effort to get the sail going as there is no pole. I'm not absolutely sure but I think of them as being smaller than a spinnaker. Closer to a very full jib. The cut of the sail would depend on your boat. High performance boats would have a flatter cut as they would reach off the wind more for speed. I think a slower cruising boat (like ours') would have a fuller cut for better running on a broad reach to dead run. D'Arcy, Shortwave
