If you ever wonder what the look of sailing in the future might be like,
take a look at the new eye-catching J/Boats with retractable carbon bow sprits and large,
asymmetrical spinnakers.
Boats like nothing you’ve seen before are appearing on the bays and
harbors of the world. They have long sprits projecting from the bow to which
are tacked huge, colorful spinnakers. Not since the switch from gaff-rigged
to Marconi mainsails has the look of sailing changed so dramatically. People
are referring to them as "sprit boats", "sport boats", or in dinghy-sized
versions they’re called "skiffs" as in Australian 18 skiffs where the
concept originated. Yet, "skiff" would hardly describe J Boats’ flagship 65
foot fast ocean cruiser, the J/65.
The Summer Olympics embraced the new look for TV cameras in front of the Sydney
Opera House. The Americas Cup now uses them. Some sailing schools and sailboat
charter operations are carrying sprit boats exclusively, convinced that they along with
the novices are going to benefit from the new technology. Sailmaker ads talk of the new
shapes in easy-to-fly downwind asymmetric spinnakers. Just about every new boat under 30
feet now features a retractable bow sprit and asymmetric spinnaker.
But sailing is one of the worlds oldest sports where traditions die hard. Sailors
can be conservative, leaning toward a glorification of the old. They may not be quick to
embrace the new. Time spent on an extra 2 coats of varnish may be more precious than time
spent sailing an extra 2 knots faster. So, the question for many is whether this is a
breakthrough product to enhance the sailing experience or some marketing gimmick designed
to get everyone to invest in new boats and sails.
Any owner of one of the new Js will give you the answer. They will tell you that the
new sprits and asymmetrical spinnakers make an incredible difference, sailing becomes easier and
more fun for novice and expert.
Whats more, the new boats benefit first time sailors and novices immediately.
Experts on the Grand Prix Match Racing Circuit praised the J/105. The J/120, a 40 footer
that won Cruising Worlds Overall Boat-of-the-Year in 1995, is so popular that
one-design racing fleets have formed on Long Island Sound, the Great Lakes and California.
J/105, with over 600 boats in 17 countries (as of April 2003), is one of the
largest offshore one-designs in the world. The J/109 has now grown to over
300 boats in less than 4 years.
The reception given the new designs by more popular handicapping bodies, has been
enthusiastic. Racing under PHRF in the Americas, IRC (formerly CHS) in Europe, sprits have
won a number of major events while at the same time providing unparalleled fun and
excitement for owners.
The new asymmetrical spinnakers help sailors by making sailing downwind
possible for two people in boats as large as 65 feet. After all, if you own a sailboat, why not sail most of the time
instead of having to turn on the motor? The new boats are far simpler to operate. To jibe
one person casts off the old sheet and pulls in the new one. To fly a spinnaker the old
fashioned way you additionally needed 4-8 people to manage complicated spinnaker poles,
pole up & down controls and afterguys. When was the last time you had 2 weeks spare
time to train a large crew?
Another reason new sprit boats work better is the crew doesnt have to fight the
boat and sails downwind in strong breezes. The center of effort of the spinnaker is
further forward and lower with more slope to the sails leading edge and with a leech
thats more open because the trailing edge never has to function as the leading edge
of a symmetrical sail. All this means that: When gusts of wind hit the sail, the boat
tends to become better balanced with a neutral helm; the back edge of the spinnaker opens
up rather than cupping; and, the bow has a tendency to lift rather than bury. So the
energy of the wind is transmitted into acceleration forward rather than a frightening
round-up and knockdown. These boats make, what used to be terrifying conditions, just
another great day to zip across the bay.
J World Sailing School in San Diego and Annapolis have fleets of J/80s, the 26 foot
sprit boat. They claim that people are having more fun in the learning process and are
advancing their skills more rapidly. In a day or so they whistle past the old salts on the
bay with half the effort.
Selection of the 49er dinghy for the 2000 Olympics in Australia and the flood of
sport boats with sprits under 30 feet across the planet serves very clear notice that this
phenomenon is here to stay. Industry insiders estimate that over $100 million of product
in terms of sprit boats and asymmetric sails have been purchased in the past few years and
the trend is up.
This revolution might have happened sooner if thered been a parallel advance in
technology. Everyone knows bowsprits and big sails go back to Columbus or earlier.
The SCRIMP resin infusion process dramatically improved the glass to resin ratio in composite
construction, 60-70% now rather than 35-40%. Flexural, tensional and compression
properties of the laminates double in strength. Weight saved in excess resin is put at the
bottom of the keel in the form of lead. A Carbon fiber mast can be added to take
100s of pounds out of the rig. Each of these steps lowers the center of gravity. A
very stable boat results, which doesnt need lots of crew on the rail or frequent
reefs to sail upright. That partially explains the get-up-and-go of these new designs.
The other part is hull shape. Apart from having fuller, more buoyant bow sections to
handle the increased power of the asymmetric spinnakers and to precipitate earlier
surfing, a lower center of gravity reduces dependency on the need for wide, fat hulls for
added form stability. A proportionally narrower hull, that slides through waves more
smoothly, is more comfortable when cruising, and faster. Less motion means smoother flow
of air around sails and less disturbed water flow around the hull.
The bad news is that old boat owners can only pick up about 25% of what these new boats
offer. To do so, they would have to buy new asymmetric spinnakers and modify their deck
layout for cockpit operated snuffer controls. Theyd still lack the retractable
sprit, hull form and 18" clearance for the spinnaker halyard mast exit above the
headstay to permit the snuffer to articulate with the spinnaker on a jibe.
The good news is that theres never been a time when youve had a better
excuse, or when its made such great sense, to buy a new boat.
