sail cloth, sail fibers, sail making

 

I am presenting a lecture seminar on the subject topic this Thursday, tomorrow, 16 Feb 2017 at Newport Yacht Club, Long Wharf in Newport. All are welcome.

This is the presentation overview and the things I will be discussing.

Fiber, fabric, film and fabrication

  • What does a sail have to do?
  • What is required to do this?
  • Background on fibers and their properties
  • Weaving 101
  • Mylar properties
  • Laminates
  • Laminated method
  • “String sails”
  • What’s next?
  • What does the weekend sailor make of this?

And thanks to Hood Sailmakers and Dimension Polyant for the cloth samples.

Hood Sailmakers is paving the way by sponsoring the drinks to the tune of the first $150 of drinks served.

This is the email flier that Roy Guay, my host for the evening and the Chairman of the Bermuda 1-2 distributed to the club’s membership.

On 16 February at 1830 the Newport Yacht Club is trying to start a Winter Lecture Series. Our own Joe Cooper will be giving a talk on Sailcloth and Sails: “Separating marketing from facts to get to Value: A discussion of Sailcloth and things to look for and why for various types of sailing. What does “Premium Dacron” really mean? Why every sail maker has “The world’s best sails” What’s the difference? Woven, Laminates, fibers, molded, not molded, a glossary and guide to sail-maker speak.”

If you are in the neighborhood drop on by. All are welcome.

Sailing Seminars for this winter

Seminars on sailing are a great way to keep the juices flowing in the winter. The menu below is a summary of the seminars I have already prepared. I can also develop custom seminars for dedicated audiences. Interested? Need to learn more?

Drop me a note joe@joecoopersailing.com and let’s discuss what can be done to keep your group fired up in February.

PASSAGE MAKING

Preparing for your next “long passage”: This seminar discusses Seamanship and 8 things to think about before you undertake any voyage so we don’t read about you in WindCheck. Regardless of the size of boat and the intended passage, whether it is to Block Is. Nantucket, Maine or Bermuda and beyond. The thinking needed is the same regardless of the destination. This seminar discusses key elements of the boat to be reviewed before leaving the dock.

FULL LENGTH BATTENS

Separating the hype from reality: Just what is the VALUE in a FB SYSTEM? This seminar discusses the aerodynamics behind the FB phenomenon, the realities for most sailors with “normal” boats, the hardware, its use, cost and the relative value for sailors.

Full Length battens CAN provide los of roach, but in this case there is not backstay. BUT this is a custom built boat intended to have no backstay.

But in order to REALLY slide up and down easily demands a comprehensive look at the sail, mast and the sailing plans plus how YOU like or want to sail

SAILCLOTH AND SAILS

Separating marketing from facts to get to Value: A discussion of sail cloth, details to look for and why for various types of sailing. What does “Premium Dacron” really mean? Why every sail maker has “The world’s best sails” What’s the difference? Why the price spread? Woven, Laminates, fibers, molded, not molded, a glossary and guide to sail-maker speak.

Laminated staysail on a 30 footer.

Do you need a “high tech” sail fabric such as this laminated staysail on a 30 footer?

Or a woven material. What gives YOU the best VALUE for your sailing?

Or a woven material? In this case a full battened mainsail made from woven Vektron on a Beneteau 40.7. What gives YOU the best VALUE for your sailing?

CRUISING SAILS & RIGGING:

Options for sail inventory: How to set up your boat for your cruising goals, now and 5 years out. What you need, why and how to maximize Value without a boat full of sails.

A cruising kite is, after you get co mfortable with it a great value when sailing in medium air. The condition most passages are made in.

 A "solent" stay is a good way to have a small sail without having to "change" headsails.

A “Solent” stay is a good way to have a small sail without having to “change” headsails when the roller headsail is too much sail. They are easy to install and can greatly expand the wind speed you feel comfortable sailing, pretty quickly.

PREPARING FOR SUCCESSFUL RACING:

It’s not just wet sanding the bottom: A review of the steps the good guys take to give themselves the best shot at being successful.

THE AMERICA’S CUP:

How a 7-year old kid ended up in two America’s cups. A look back thru the history of the Australian challenges for the America’s Cup beginning in 1958. How Australia got into the act, how a 7 year old kid was infected with the disease and what it was really like sailing a 12 meter in the late 70’s and early 80’s. Cooper was the youngest crew in 1977 and the boat keeper on Australia in 1980-working for the syndicate for 18 months and sailing as Grinder/Sewer man.

One of the signature images that lured me to the America's Cup. The 12 meter Dame Pattie pricticing in Sydney Harbor in 1967. I was 12 years old.

Family fun sailing

For the past few months I have been coaching a fellow, Don Dwyer, in Branford CT (USA) in order that he and his very green crew could participate in Block Island Race Week. It has been a fascinating prices with lots of great moments.

He sent a team email letter out on Monday, which I reproduce here.

BEGINS

Team,

And I mean Team in every sense of the word, Amber Waves flew home under spinnaker Saturday ending a 6 month journey that by all accounts was a resounding success.  In our third season of sailing we accomplished something that quite a few people questioned was possible.  We met or exceeded every goal I set out, to be safe, to be inclusive, to have a ball, and to be as competitive as we could be.  Of the many highlights that will feed our dinner table discussions for years two stood out for me.

Tuesday’s race in 20-30 knots of wind was described by others as “brutal”, “carnage” and “epic”.  Ken Read, one of America’s most accomplished and famous sailors congratulated the Storm Trysail Club’s Race Committee for having the courage to hold the Round the Island Race in such difficult conditions.  He said racing in those conditions would provide memories for a lifetime.  I felt we sailed extremely well and I never felt we were outmatched by the conditions.  I was concerned that after 5 hours of sailing we would be met by thunderstorms near the finish and that we didn’t have the experience to deal with a major equipment malfunction.  But we were still sailing for the same amount of time as the leaders in the race in the toughest conditions of the day.  I will remember that day of sailing forever.  If you haven’t seen the article Joe Cooper wrote about us check out the WindCheck post on us.

Winning the start on Friday was one of the greatest thrills in my sporting life.  We knew we couldn’t compete with the bigger, faster yachts or the more experienced crews over the course of the race.  But nobody told us we couldn’t beat them to the line.  We hit the line hard on the wind, going as fast as Amber Waves will go with a lot of yachts half a boat length behind us.  What made this even more incredible that 20 minutes before the race I wasn’t sure we were going to make it to the race.  The seamanship displayed by Sherb and Pat was off the charts.  When the sheath of the main halyard gave way  they re-rigged our running rigging and got us back to the starting area with 10 minutes to spare which allowed us to mix it up with our competitors.  That was the kind of cool, calm, quick behavior we will need when we move up to blue water ocean racing.

On the competitive side, I think we did great.  We beat at least one other boat on 3 of the 4 days we raced and we were ahead of some when we retired on Tuesday.  The one day we came in last can be attributed mostly to splitting from the fleet.  My bad.  But all in all I think we sailed up to our ability every day and never stopped searching for more speed.  We will continue to improve.

I want to thank all of you for your commitment to the project.  On the sailing side, the core of sailors that showed up for practices, drilled, tacked and gybed till they were exhausted made it possible for us to take anyone that showed up out racing.  On the non-sailing side, everyone pitched in.  We ate incredibly well, had a clean home every day, everyone got shuttled where they needed to be and no one was never not on time.  That effort made life so much better for Jan and me.  So thank you everyone.  In particular I want to thank:

Joe Cooper.  It is the understatement of all time to say we could not have accomplished this without your leadership and guidance.  The only way I will ever be able to adequately repay you is to spread the word that other sailors with limited experience seek out the kind of instruction we got.  Thank you.

Wills and Zach.  They sailed every day, did both deliveries and basically never stopped working.  And did all that without being asked.  We had no idea when these two fine young men came on the boat they would play such an integral part in our success or have such an impact on our enjoyment of the week.  If I ever hear anyone bitch about the next generation I will point to these two.

My darling wife, Jan.  The Boat Mom took care of everyone from the initial idea to the last drive home.  There was nothing we did that Jan didn’t touch, run, or organize.  I adore you.

So what’s next?  Golf.  For a little while.  Amber Waves is likely down for a week or more.  The old girl took a beating out there.  We will resume Wednesday night Around the Buoys racing as soon as able and there may be a couple more shorter regattas but we will let this one sink one for a while before making any decisions.  Don’t worry I will be in touch……

Safety at Sea seminar

On Saturday 07 Feb 2015 at the Safety at Sea seminar, produced by LandfallNavigation, I will be presenting a section on sails & sail fibers. This nearshore Safety at Sea seminar is being held at the Mystic Seaport in Ct. from 0800-1630

The following is a table of the basic properties, sailmakers are interested in, of the fibers currently used in making sails. In an earlier day, this information would be distributed at the event, but today, well it is here.

The information is from the North Sails website attributed to research by their cloth people

Sailing coaching and sailing systems consulting

If you are reading this website you are most likely a sailor. It is a great activity and can be very satisfying, but for many folks, especially those who came to sailing later in life, there are some things that can make a nice day on the bay, well, not so nice. Ring a bell?

  • Do you avoid using your cruising spinnaker, or shun the idea of one because it is “too complicated”?
  • Would an easier way to set, trim, and lower your cruising spinnaker add value to the day’s downwind sail back from say Block Island, for those of you in the NE?
  • Do your headsail sheets always get caught in the shrouds thus slowing down the tack and making for a big grind by the “grinders”—aka your spouse, partner, non sailing buddies or the kids?
  • Have you dreamed of making a longer passage, regardless of destination, something that pushes your comfort zone pretty hard, but  just cannot get all the details, equipment, and systems coordinated?
  • Would you like to improve your anchoring, mooring, and docking skills?
  • Do you race, or want to race but have difficulty training and organizing crew?

If, like many weekend sailors, these are just a few of the small (or large?) tensions experienced while sailing, relax. There are solutions to all of them.

All you need is someone who can identify the problem and show you ways to solve it. Someone with skill across a wide range of boats locations and scenarios. Someone professional. In short, someone like me.

Solving Your Sailing Challenges

I have worked with clients to solve their sailing challenges and enhance their enjoyment of sailing. During countless hours on the water with clients — both new sailors and experienced boat owners — I have:

  • Created more efficient deck layouts &  improved sail trimming tools
  • Coached couples and Bermuda race crews on spinnaker flying and more efficient ways of tacking
  • Organized crews, both racing and cruising and coached them in more efficient operation on board
  • Developed fast, simple, and relatively inexpensive ways to set small sails under a large, light, and full 150% roller headsail, which as we all know is not much good in 20 knots, is it?
  • Increased clients’ understanding of sail shape, and their skill in manipulating sails
  • Consulted on upgrading hardware — both the equipment and creating the techniques to make better use of the hardware (rather than merely adding some new shiny widget in the hope that all will be better)
  • Coached clients on faster and easier reefing methods

It makes sense to try and maximize the “Fun Factor” (AKA VALUE) of each day (hour) on the boat, especially in the Northeast where we only get half as much time as balmier climes.

Call so we can discuss the following services to improve the value of your sailing hours:
1.    An on-site review of your boat and its deck layout and equipment with you including an extensive interview to prepare a list of things to make sailing easier
2.    Managing the upgrades with your yard or rigger in the event you want to proceed with my recommendations
3.    Onboard coaching for cruising, such as ways to set and douse the cruising spinnaker, answers to sail trim techniques and integrating the techniques into the system
4.    Offer racing coaching on strategies & crew work & related organizing
5.    Consulting on preparing a boat for an offshore passage

I look forward to your call.
