Utility Power Sail (UPS)

Doyle UPS Tartan

The Doyle Utility Power Sail (UPS) is the link between a headsail and a spinnaker, with a wider usable wind range than either. It's the first sail for cruisers who've done away with cumbersome, overlapping genoas but don't want to give up power in light air, or performance at any wind speed while reaching or running.

UPS Advantages

The UPS is lightweight.
Large, light corner patches holds shape and allows the sail to float free from the boat.
It sets and furls on its own luff rope and furler.
It goes upwind and downwind.
It flies like a spinnaker, but cannot collapse like a spinnaker, even when sailing as close as 33 degrees apparent.
The effective wind range of a UPS is 33-180 degrees apparent.
The UPS sets on its own flexible Vectran line so there's no need to remove your furling genoa, and it stores in its own bag when not in use.

The UPS Design

Doyle UPS Diagram

When sailing hard on the wind the jib and main work almost as one, and thus the combined elliptical profile determines the aerodynamic efficiency. When eased off, or reaching, the sails act more independently and the geometry of each is critical to performance.

The sail designers at Doyle have developed shaping techniques that support critical roach area in headsails without the need for battens so you can enjoy the efficiency of an elliptical form and have a sail that can be easily furled!

Thus, not only does the Doyle UPS provide more area for light air and for off the wind sailing, it provides much greater efficiency!

UPS Customer Testimonials

We flew the UPS for the first time this weekend. I am very pleased. Easy to launch and retrieve. Can't believe how easy it was to furl in. I'm going to get a furling line approx. 25' longer and then I will be able to furl it in from the cockpit while releasing the sheets i.e. I'll be able to sail it solo. The Harken 1899 is fine. I'm glad I went with it.

With the wind at 11-12 knots from 94 degrees true, we were moving at 7 knots. I'm excited that now I'll be able to sail in 10 knot conditions, which we have a lot of on the Bay. Got a lot of comments from our friends on what a good looking sail it was.

Thanks,

Lyle Erickson, Hunter 466

As you may remember, we purchased a Doyle UPS Sail for our Caliber 40 LRC earlier this year. This sail is the best thing that has happened to our boat. Heavy boats sail very slowly or not at all in the all-too-frequent light air of Tampa Bay and the west coast of Florida. This sail allows us to enjoy sailing in the four to eight knots of wind that previously required use of the "Yanmar Jib". It has turned motoring days into sailing days. More amazingly, we can sail to windward with it; I'm just amazed at how high we can point with this sail.

Finally, the roller furling makes setting and retrieving it a breeze. Our previous boat had an asymmetrical spinnaker, and it was a hassle for one person, even with a sock. This UPS is a snap to use, so we don't hesitate to put it up.

We plan to go cruising for several months next spring and look forward to being able to sail rather than motor much of the time.

Again, thanks for a great sail and the excellent service you provided along with it.

Finally got some good weather to test the new UPS. Believe it or not, we've had 10-20 all season, but this weekend was perfect, with 1-10 kts poking around the islands in Casco Bay.

The UPS was easy to work with and performed very nicely on all points of sail. In a close reach we were getting 2-3.5 kts thru the water with 1-2 kts apparent. Only takes 1 knot indicated to keep it full. I was especially surprised that we could pinch up tighter than with the blade jib. I found that in really light air (1-2kts) it pays to ease it out to get a rounder entrance at the luff. I like the way it is cut up high to the clew, so it doesn't block forward visibility like the 153% genoa.

Since it's so easy to furl, I roll it up rather than trying to tack it around the outside. I rigged the sailbag on the forward hatch as you suggested, so unclipping it from the bow roller and dropping it down into the bag is simple. It'll get even better once it loses some of the stiffness. Since it's so easy to deploy, I'll probably use it rather than change up from the 110 to the 153.

The dismayed looks on the faces of the Sabre owners as we blew past them was worth the price of the sail. A very nice investment overall!
