HOW WE MAKE A GREAT CRUISING GENOA LAST EVEN LONGER


Our original Passagemaker II came from our experience with Tape-Drive racing sails. These original load path sails had proven themselves to be the most durable high tech sails on the market. They are light, strong and reasonably priced.

To make the Tape-Drive Passagemaker II even better, we now offer an option of a Dacron chafe guard. Pictured above, this chafe guard, covers the after part of the sail that comes in contact with the mast and rigging and the lower part of the sail that comes in contact with the lifeline stanchions and the bow pulpit.

It can be installed on both sides of the sail as in the picture or on one side when the sail is made of a laminate that has a Dacron taffeta on the opposite side. In either case, the laminate film is completely covered by a woven material that is far better at absorbing the punishment the sail receives with each tack.

The new Passagemaker II also offers a number of options for combating the sun. Besides the old standby Sunbrella sewn to the exposed areas of the leech and foot, a recently introduced fabric called WeatherMax offers a lighter version with roughly the same protection. Both Sunbrella and Weathermax are available in a wide variety of colors. Even better from a weight point of view is a UV treated Dacron which is stuck to the sail using a pressure sensitive adhesive. The makes a lighter, smoother cover but one with a shorter life span than those mentioned above.

Finally for those cruising sailors who want maximum performance, we offer a furling sock that is pulled up over a furled sail using a different halyard. The socks are slightly more expensive than a sewn on cover and are a little more bother in that they have to be hoisted and secured in place but they offer the ultimate in protection and allow your headsail to offer the ultimate in performance. The socks are made in colors that can match your mainsail cover.



Reefs are still part of what the Passagemaker II offers. As shown in the picture above, we provide reef patches to furl to so the corner load is distributed properly. We do not recommend roller reefing your genoa beyond a few turns of your furling unit in order to avoid overloading the material that remains exposed. It is important to remember that even though the sail has gotten smaller, the sheet load is much greater because wind load increases with the square of apparent wind velocity.

J/80 SPINNAKER DEVELOPMENT PRODUCES QUANTUM LEAP FORWARD
Photo: Guy Nowell, Editor, Sail-World Asia

UK-Halsey continues to develop our world championship winning J/80 sails. Our new generation asymmetrical spinnakers have proven much faster than the sails used in the 2010 Worlds. At the Phoenix Cup, which was sailed in Hong Kong Harbor and broadcast on Chinese TV, the boats with UK-Halsey’s new spinnakers came from behind and passed the boat that was leading the race at the windward mark.

The race was Louie Perfectua’s at the last windward mark. He sailed to a 20-boatlength lead by splitting from the fleet to play the opposite shore of the harbor while looking for current relief. But the run to the finish was less kind than the beat up. While Perfectua jibed downwind sailing hot angles, there wasn’t enough breeze to get a J/80 planing; the extra distance took a toll. ‘Low, slow, and straight down the middle’ turned out to be the program. Jeff Johnstone sailing JELIGNITE, sailed right by and so did ALCHEMIST. Perfectua later acknowledged that the v2.0 J/80 asymmetrics being used by most of the fleet (but not him) allowed for deeper running. He was impressed with the leap in performance.

LAMINATE SAILCLOTH UPDATE
by Rob Muschamp, Bainbridge International
I remember setting up for the 1981 St Pete Boca Grande race in what we thought was the most advanced sail fabric known to man. At the time, it really was. It was a very simple Polyester taffeta with a single layer of mylar laminate. As we finished the race and lowered the sail, we immediately went below and began inspecting it feverishly to ensure we had not done any damage. (All without our generous owner’s knowledge) “All-SET...NO DAMAGE.....The sail is good for another day.....”

This sail is nothing compared to the sails we are producing today, but what has really progressed since then??? The biggest explosion and extreme development has been in the area of fiber development and acceptance into sailmaking. I am going to include a little table that we have been using for years. It compares different fibers amongst 4 different parameters: Modulus (resistance to tear) Tenacity (resistant to stretch) UV resistance, and flex loss. I do not want to get too wrapped up in the absolute numbers that are listed here, but they are useful in comparing different fibers.

Fiber Modulus Tenacity UV Resistance Flex Loss
         
Polyester 80-120 5-8 6 months 0%
Pentex 250 10 5 months 5%
Twaron 600 23 3 months 25%
Carbon 1200-2500 20-40 No effect 30-100%
PBO 1600 36 1.5 months 30%
Spectra 1100 34 7 months No effect
Vectran 580 28 1.5 months 15%
Technora 550 28 3 months 7%


By looking at these numbers, we can see some really glaring differences. These differences can also help explain why certain fibers are not suitable for sailmaking in an overall sense. PBO, for instance, came on the scene with a lot of hoopla and was all the rage, until we took a closer look at the fiber, and found, that as good as it seemed initially, (and we made some really light/strong sails) that the UV qualities precluded it from being as good a fiber as it was initially thought to be. We might make a similar assessment about Carbon, and its suitability for say, cruising sails, because of its low flex loss number. However, Carbon is an excellent choice for high-end cruising sails. Why? Well, we found that if we add polyester or Dyneema taffetas to the lamination, the flex loss is severely reduced, and what you end up with is a fiber combination that is extremely resistant to stretch, is not subject to UV degradation, and has flex loss that is totally in the acceptability range.

So, what fiber is best for my sail??? Simple question right??? The answer is not so simple. First you must determine the kind of sailing you do, and your budget. If you race a lot, a Carbon or Twaron sail, (or combination of both) is going to make quite a nice sail to keep you out in front of the pack, but you will be paying more for that sail, and replacing it quicker, than say a Polyester, or Pentex sail. Why??? Because the Carbon and Twaron fibers have significantly better resistance to stretch, but more expensive and they break-down at sometimes better than twice the rate of Polyester or Pentex.

Construction. Laminates are made by bonding together layers of different materials to form a sandwich. A simple laminate will consist of an open scrim of fibers with a layer of film bonded to each side. The film stops air blowing through the laminate while the load is taken by the scrim. laminates are far more efficient than wovens as the fibers have no crimp.

The lightest most efficient style we can build is a construction where we encapsulate an open scrim inside a layer of film on each side. We commonly refer to this construction method as film-on-film, or more simply film/film construction. This construction technique is usually reserved for race oriented sailors, as the lightest sail possible can be achieved. We can also decrease the overall weight by reducing the film thickness, on each side of the scrim. In addition, we can add fiber in multiple directions. This tri-axial construction reduces hinging, a known cause of laminate breakdown and shrinkage.

If we want to take this step further, we can add light taffetas (light layer of polyester woven fabric) to the outside of either 1 or both sides. Though the addition of taffetas will not change the stretch characteristics of the fabric significantly, these taffetas will add a substantial amount of durability, and chafe resistance. The addition of taffetas on any fabric will increase its weight dramatically. These constructions are very popular amongst cruising sailors, who desire a more efficient sail, but want to build in a extra little amount of ruggedness.

Radial or Crosscut?? Having now decided that it is a laminate sail I now want, and I am pretty much sold on a higher end fiber choice, I have one more hurdle to jump before ordering my sail. Do I want my sail to be radial or Cross cut? In simple terms, do I want my sail to have the seams roughly parallel to the water, or do I want the panels orienting out of each corner. As in these two drawings…



What??? There is a choice here. I thought all crosscut sails were for cruising guys and radial sails for the racers (like me). Well, this was the case until just a few years ago. As laminate construction began to mature, we found that it was better to run the fibers in the warp direction to avoid crimp, (which leads to stretch).



Lately, with the advent and sophistication of lamination techniques, we are now able to offer cross cut laminate sailcloth that is just as efficient as its radial brother. These fabrics are excellent stand-alone fabrics, or serve as excellent base materials for tape based sail construction methods. By taking one of these modern cross-cut materials similar to Bainbridge’s Diax 2, and introducing longitudinal re-enforcing tapes that overlap the seams, we can create a structure that is stronger than that of a simple cross-cut (or radial) sail. The weak point in any sail is the seam. By crossing the seams with these reinforcing tapes, which can be of Carbon or Twaron, or a combination of other fibers, we can significantly reduce the fail point of these sails. Here is a drawing of a UK Tape-Drive sail. Notice that the load bearing tapes crossover the seams, adding strength and integrity to the entire sail. This structure provides a light, efficient, durable membrane capable of withstanding the rigorous loads that sails are subjected to.

FAST BOATS COME FROM GOOD CREW by Jeff Tyrrel

One thing that becomes clear when folks talk about how to grow our sport and get more boats involved in competitive sailing is the need for good crew. From a boat owner’s perspective, they wish to bring aboard crew that has some level of experience that can help their campaign be successful. Conversely whenever one engages fellow sailors about looking for good boats to sail on, solid programs to join, the common theme is one of a competitive ride that is fun to sail on. The better crew tend to gravitate towards the more established boats as they offer the gratification of being part of a winning effort. That is all well and good for the boats and crew that are in the habit of finding their way to the podium, but what about boat owners wishing to up their game or crew looking to improve their skill set?

All good boats rely on the individuals who make up the crew and their contributions to the greater effort directly affect how she will fair on the race course. The successful skipper will provide an environment where the crew can evolve to become part of a winning campaign. To achieve this there must be a level of expectation. Each crewmember must honestly identify what they can contribute, as well as what skills they can learn or improve at. Beyond that each member of the crew must also consider how they can help other team members learn and excel.

Preparation wins yacht races.

SPRING LINE CONTROL
Sail across the ocean and dock a boat like a pro. At www.skippertips.com Captain John Jamieson, with 25+ years as a master mariner, has developed a unique, step-by-step training method that will show you the skills you need for safer sailing anywhere in the world. Here is an excerpt from his highly popular eBook "Dock a Boat like a Pro!"…

Two multi-million dollar sport fishermen are docked flush against the fuel dock. The dockmaster has told you to lie alongside in the narrow space between them. You will have about a foot on each side once you dock.

How can you bring your boat alongside under complete control? Let the pros guide you with these easy steps...

When docking alongside a pier or seawall between two boats, aim for a spot aft of the forward boat, equal to about 1/3 of your overall length. Be sure to include any projections like a bowsprit or anchors in your calculation. Point your bow toward this "aim-point" on your approach (see illustration on right).

Here's an example. Let's say you have a 30 foot sloop, with 3 feet of bowsprit and anchors. You would aim about 11 feet (1/3 x 33) aft of the forward boat. Once the bow reaches the aim-point, use an after bow spring to hold your position and work the stern in to the pier. We will talk more about wind and current approaches in Part IV of this e-book. But for now, we will make our approach with no influences from wind and current.

Estimate 1/3 of the overall length of your small cruising boat. Include bowsprit or anchor projections. Use this to locate the "aim-point" (yellow star) along the pier.

WARM FRONTS
Warm fronts by definition -Boundary separating the leading edge of advancing, warm, humid air from retreating cooler air.
  1. Associated with low pressure systems mostly in northern Latitudes north of 25n where there are differences in air masses.
  2. Not found usually south of 25n in the tropics where air masses are usually uniformly tropical in nature.



On a surface weather map, a warm front is depicted as a line with rounded bumps on the cold side of the line. On color charts the warm front as shown in red.


  1. Advancing warm air humid air lifts up over the colder air producing cloudiness then precipitation.
  2. Cloudiness first appears as high thin cirrus clouds as the warm front approaches.
  3. Cloudiness thickens and lowers eventually into a low stratus overcast.
  4. This then develops into steady precipitation (rain or snow) and may last up to 12-18 hours depending on how fast the front is moving.
  5. Dense fog at ground level is common very close to the actual boundary.
  6. 6) Occasionally thunderstorms develop along the warm frontal boundary in the late spring and summer months.
    a) These storms usually are not severe but may contain a lot of lightning.
    b) They are most likely late night/early morning hours when atmosphere can be more unstable.
  7. Once the warm front moves thru the clouds lift and may break into partial clearing.
    a) Temperatures and humidity take a sudden jump upward.




Wind characteristics of approaching warm fronts

  1. Winds ahead of approaching warm fronts are usually easterly (NE-E-SE)
  2. Wind strength varies depending on strength of the low and high pressure systems near by.
    a) But wind speeds can reach gale force especially in intensifying systems in the Atlantic
  3. Sometimes though the wind at the surface on the cold side of the front can be somewhat lighter than grib files indicate.
    a) Stronger winds are lifted vertically and do not reach the surface.
    b) This is probably more common over land than over water.
  4. As you cross the warm front into the warm air winds shift abruptly to S-SW .
  5. Often the strongest winds are found on the warm side of the front in the warm sector of the low pressure system.
  6. In this warm sector the full potential of the wind can be realized as stronger winds aloft are easier to mix down to the surface.
    a) Southerly gales are often common in the fall south of warm fronts moving northeastward off the East Coast of the US eastward to Europe.
    b) This can raise havoc in the fall delivery season.
  7. The area just south of the warm front but also close to the approaching cold front is an area that should be avoided.


    a) It contains the strong wind potential of the S-SW winds in the warm sector.
    b) But also is likely to have squalls even higher from the approaching cold front.

ANY GAME WORTH PLAYING NEEDS TO BE PLAYED RIGHT:
REVISITING THE FUNDAMENTAL PRINCIPLE OF SAILBOAT RACING


For those of you who are serious racers, there was a very important article about the racing rules that appeared in Sailing Scuttlebutt, issue #3302. The article was written by Peter Wilson, a well known and respected Senior Judge and Umpire and if you haven't read it, you should.

From time to time, UK-Halsey Sailmakers publishes articles on the racing rules written by Rob Overton. Rob is the current Chairman of the US Sailing Racing Rules Committee, an International Umpire, a US Senior Judge and a member of the Florida Appeals Committee.

We are pleased to publish Rob's thoughts on Peter's article.


In Scuttlebutt #3302 Peter Wilson writes an interesting article, "Is the 'Fundamental Principle' Still Relevant?" The Fundamental Principle (which is on the page facing Rule 1 in the Racing Rules of Sailing) says "Competitors in the sport of sailing are governed by a body of rules that they are expected to follow and enforce. A fundamental principle of sportsmanship is that when competitors break a rule they will promptly take a penalty, which may be to retire."

It's the last sentence that Peter addresses in his article. He points out that this principle seems to apply less and less, these days, and I think most of us would agree with him. Competitors rarely protest, or, if they're wrong, take voluntary penalties, even for blatant fouls.

This lack of action is, as Peter points out, bad for the sport – it discourages people from learning the rules and frustrates those who abide by the rules when they see others behaving badly on the race course. It's also bad for kids to come to the conclusion (or be taught by their coaches) that it's OK to cheat.

Peter proposed some ideas about what to do to get sailors to respect and follow the Fundamental Principle, but I think there's only one solution: we need to change the culture of competitive sailing. That means we should, as a group, encourage valid protests, strongly encourage sailors to take voluntary penalties, and improve the protest process so it is less rigorous for the protestor and more consistent in the outcome. And we should never encourage or allow our kids, our coaches or our friends to break rules without taking a penalty.

BELGIUM NOW SERVED BY TW0 UK-HALSEY LOFTS


UK-Halsey Belgium has just opened a service loft in Nieuwpoort, which is the third largest harbor in Europe! Having a loft in the middle of this active harbor will help UK-Halsey serve many more Belgian sailors. The Nautical Center building, where the loft is located, is filled with businesses catering to sailors every need. There’s a chandlery, engine mechanics and now a sailmaker. The new sercice loft is large enough to store some sails and handle small repairs. The main loft in Oostende will produce new sails and handle the repairs that are too big for the Nieuwpoort loft.
