Like many industries, sailmakers are experiencing delays in delivery in the last few months due to sailcloth delays, transport delays and many other issues. However, Mark Mansfield from Quantum Sails Ireland says the loft has some decent stocks available and spinnakers, in particular, can be supplied quite quickly.

So if you are thinking of upping your performance for the second part of the season, and your present spinnaker is soft and retains a lot of water, maybe now is the time to raid the bank account and come out with a shiny new kite that will set quicker, be faster when full, and not run the same risk of tearing.

Older spinnakers are not as quick or efficient for various reasons:

  1. When soft and limp, they are slow to set when hoisted.
  2. An old spinnaker eventually becomes porous, and the wind works its way through the cloth, so less pulling power.
  3. A shiny spinnaker will gybe easier, particularly with asymmetric spinnakers, where the spinnaker slides along itself.
  4. If an old spinnaker goes even partly in the water, it will act like a sponge and drag the rest in, whereas a new shiny spinnaker often just 'dances' on top of the water.
  5. An older spinnaker is much more likely to tear or blow out, as the threads joining the sail and the cloth itself start to fail due to age.
  6. Finally replacing a spinnaker offers the opportunity of changing the size required, so maybe going larger if a little underpowered downwind, or perhaps going smaller to make it more manageable and lower the rating. Perhaps even a change of shape can be accommodated so an old full running spinnaker could be replaced with a more all-round radial spinnaker.

As I reported in November, top results have been coming hard and fast for Quantum Sails clients in events such as the TP52, RC44, Club Swan 50, Melges 32, Club Swan 36 and other international classes, where boats with Quantum Sails are winning some of these important World Championships.

It is no surprise then that this has translated into orders for new sails from the racing community in Ireland. Quantum Sails Ireland has had tremendously strong Autumn and Winter sales so far, with orders from all parts of the country.

Owners understand that our sails are fast, our product durable, and our pricing is competitive. In particular, the competitive large and middle-sized race boat owners seem to be looking to Quantum as a great alternative.

Recently, we have agreed on some sails for the Grand Soleil 44 Samatom, which won the Sovereign's Cup last year. Also in Howth, we have a full suit of sails ordered for a new Cape 31.

We have some new sails for a J/122e that also just arrived into Howth and, in addition, new upwind sails for a well known J/109 in Dublin.

New Quantum sails are going on the J122 Kaya, which won the ICRA Nationals overall last September, plus a host of other race boats from Cork, Kinsale, Fenit, Waterford, Greystones, Arklow, Galway, Northern Ireland and other areas.

In addition, our strong position with cruising boat owners continues, with many cruising owners opting for more upmarket sail and construction choices.

Quantum's Galway sail loft

We have a full-sized loft in Galway where sails can be inspected fully opened out, and any work needing to be done can happen quickly.

This is an excellent advantage to us, as owners can send in existing sails to be inspected and repaired with the benefit of viewing the sails fully laid out. Not every sailmaker in Ireland can offer this full-size loft option.

With the sailing season looming, sails can still be ordered for Spring 2022, with delivery on new orders generally only taking circa 8/9 weeks from receipt of a deposit.

Mark Mansfield of Quantum Sails Ireland on the factors to consider when building a downwind inventory

Quantum's speciality line of high-performing downwind reaching and running sails are versatile, easy to trim, and tailored to the unique characteristics of your boat and your type of sailing. They're designed with the goal of helping you get the most out of your experience and your time on the water.

REACHING SAILS

Sometimes referred to as "code zeros" or "code sails," the category of reaching sails gets confusing quickly as the term can apply to a broad range of sails. To simplify and clear up any confusion, Quantum developed its line of reaching sails around the target apparent wind angles. After all, this is how we actually sail! Our three sail options are defined by possible apparent wind angle and overall optimum range. Each reaching sail line is available with a traditional torsional cable or as an XC cableless sail with a structured luff.

XC REACHING CABLE-LESS OPTIONS

More than four years ago, racing sail designers began experimenting with ways to remove the traditional torsion cable used in the luff to not only enable furling reaching sails but also to reduce headstay sag and achieve superior performance in a wider range of angles. Quantum led the way in structured luff or cableless technology with the successful Maxi 72 class. This technology has been refined and enhanced to make it accessible to racers and cruisers alike. While not practical for all downwind sails, Quantum's XC structured luff technology and designs are great for reaching applications like the AWA 40, 60, and 80, and are available in membrane or tri-radial construction to meet the needs of any sailor.

GREATER BOAT SPEED & WIDER ANGLES

Quantum's XC reaching sails have more luff projection to weather and more twist (five to 10 degrees) compared to traditional reaching sails and other cable-less designs on the market. The superior performance is a result of a straighter, more stable leech and a flatter exit, both contributing to an increase in drive in all conditions but not overpowering the boat in heavy-air reaching. And because there is less surplus material along the leech, there is less backwinding of the mainsail, which creates less drag when sailing close to the wind.

Running sails

RUNNING SAILS

Downwind sails fall into two categories: reaching and running. For broad angles, Quantum's line of spinnakers fits the bill. Quantum's A3 is an all-purpose asymmetrical spinnaker and covers the mid-range, while the A2 is designed specifically for broad-reaching and running performance. 

SUPERIOR PERFORMANCE: MID-GIRTH, DEPTH, & THE BALANCE BETWEEN LUFF & LEECH AREA

Understandably, sail size is a critical design feature. The optimum foot length for any downwind sail is a function of aspect ratio or the height (luff) versus width (foot). When too tall and skinny, the sail won't be stable. Too wide and short, and the sail will not twist properly to achieve the right flying shape. No matter what type of downwind sail you are building, you have to start with the correct aspect ratio for the boat's rig proportions. This is what dictates size. The next consideration is the girth of the sail halfway up; this is known as the mid-girth. The smaller the mid-girth, the more genoa-like the sail becomes and more capable at closer apparent wind angles. Bigger mid-girths equal wider apparent wind angles. At the small end of the spectrum, genoa will have a mid-girth of around 50%; at the top end, a running asymmetrical spinnaker will have a mid-girth of over 100%. Quantum's AWA 40, 60, and 80 cover everything in between.
Overall depth is another important variable. A flatter sail means closer apparent wind angles and a fuller sail means broader angles. As a sail gets wider mid-girth, additional depth is necessary to support the area so that the sail will hold its shape and not just flap at the edges.

The final variable to consider is the amount of area outside the straight-line luff and leech. For close apparent wind angles, the luff will be straight and any additional girth will be in the back end. As you design for wider apparent wind angles, this balance gradually changes, with more of the sail's width shifted to the front end. A running sail has a significant amount of area forward of the straight-line luff. When the sheet is eased, this area moves past the centerline and projects to windward. This is what allows the sail to perform in broad apparent wind angles.

DOWNWIND SAIL HANDLING

BOTTOM-UP FURLERS

Bottom-up furling systems work the same way as conventional headsail roller furling systems. The tack is fixed to the drum at the bottom. As the drum turns, the track winds around the cable or the structured part of the luff instead of an aluminum foil. The sail furls from bottom to top. Bottom-up units are a perfect option for the genoa-like AWA 40 and 60 reaching sails, as the top of the sail is not too wide. The mid-girth should be around 50% and generally no larger than 60-65%.

TOP-DOWN FURLERS

As downwind sails get bigger and the mid-girth increases, it becomes harder to get the top of the sail to furl if you start from the bottom. With top-down furlers, the head is attached directly to the swivel, and the tack is secured to a free-rotating fitting on the drum. As the furling line is pulled, the tack lags behind and the sail furls from the head to the tack, capturing the hard-to-furl top sections first.

SPINNAKER SOCKS

No matter how well the furling system works, there are still limits. Full size broad-reaching and running spinnakers have mid-girths of as much as 100% and are very deep. Even with a top-down further, these can be problematic to furl. As a rough guideline, if the mid- girth is over 88-90% of the foot length, all bets are off—it might furl, it might not. As a result, a spinnaker sock is the better, more reliable option. In fact, it is also a good option for any full size asymmetrical spinnakers, even if you do have the ability to furl it. Also in the plus column for spinnaker socks, they are more cost-effective.

MATERIALS:

NYLON VERSUS COMPOSITES

For more traditional asymmetrical spinnaker sails such as the A3 and A2, nylon continues to be the best material, but it is not necessarily the best choice for the new generation of specialized reaching sails. In order to handle higher loads at closer apparent wind angles, a stronger material is needed. The best material choice is based on boat size, righting moment, and target apparent wind angle. In some cases, the best option could be as simple as a heavier nylon or polyester spinnaker cloth, but often a composite material with more strength and durability is the better choice. Quantum's proprietary Fusion M™ tri-radial construction process is used to create the ultimate custom structure for membrane reaching sails. Quantum collaborated with industry leaders to develop a range of composite materials specifically for high load reaching sail applications.

BOAT CHARACTERISTICS

A boat's design has a big impact on which downwind sail option is right for each sailor. For more traditional cruising boats with large foretriangles and overlapping headsails, reaching angles are well served by a large genoa. An A2 or A3 rounds out your sail inventory to cover the broader angles. Conversely, modern boat designs tend toward small foretriangles with non-overlapping jibs. These smaller headsails lack the punch of their larger genoa cousins when it comes to reaching. AWA 40, 60, or 80 reaching sails fill this gap. Some other questions to address when determining your boat's best sail options: Is there a bowsprit? Is the boat a multihull? Where are you sailing? How fit and enthusiastic is your crew? Quantum's experts can help you sort these and other questions to make sure you get the perfect downwind sail option for you and your goals.

ONBOARD

DOWNWIND SAIL CARE

Even underway, it's always preferable and recommended to lower and properly pack and store downwind sails whenever they're not in use or won't be used for an extended period of time. Most of the time, a properly furled and protected downwind sail can be safely left hoisted and ready to go, assuming the conditions are relatively benign. However, if it gets windy, it's best to take down furled downwind sails. Unlike a furled working headsail, a furled downwind sail is not supported by a fixed furling system and can easily start to unfurl in strong winds. Aside from not using a UV cover, leaving a furled downwind sail up is the fastest way to shorten your sail's lifespan − or flat-out ruin it. No matter the conditions, at the dock or mooring, Quantum recommends never leaving the boat with a freestanding furled downwind sail aloft!
