J121

A 40’ Offshore Speedster with Less Crew

The new J/121 (pronounced 1-2-1) is a 40’ offshore speedster that can be day raced or distance sailed by just 5 or less crew…. the best short-handed J ever…. capable of winning on any race track while also excelling in daysailing and weekend mode. Here’s a boat, class and program that redefines sailboat racing as a recreation and shared adventure with friends, reducing the focus on specialization and athletic short-course W/L racing.  The J/121 fulfills the growing need to simplify life and reconnect with those you really want to sail with on a boat that’s pure magic to sail.

Why a New 40 Footer?
Sailing continues to adapt to the rapidly changing demographics, technology and social trends of an ever more hectic world.  As our lives become more fast-paced so does the need to escape from the time constraints, pressures and burdens.  “Always on, always connected” is leading the drive to “get away” to a place that can nourish and recharge the soul.  Nowhere is that more evident than the extraordinary growth of adventure travel, providing people a much needed outlet through outdoor, shared experiences with others.

The challenge is trying to align 8-10 people onto the same schedule.  This obstacle alone is impacting keelboat racing participation across the board in most areas. Just as technology is making it easier to sail, the over-reliance on crew is making it more complicated.  Two of the positive growth areas in sailing today are one-design class racing in trailerable boats, and short-handed day racing and fun point to point events.   The global success of the new J/70 is a direct result of pent-up demand for an affordable one-design with a pre-planned circuit and easy entry.  The travel and event logistics for four people are infinitely easier than that of 8-10.  For those sailing larger keelboats, it’s the charity pursuit races and day distance events like San Francisco’s Three Bridge Fiasco that are becoming increasingly popular.  And it’s no surprise why.  These events pack a lot of sailing fun and adventure into more acceptable, smaller doses that require less practice and time to manage.

The J/121 is designed with both of these trends in mind.  Imagine a fleet of high- performance, offshore-capable speedsters sprinting along point-to-point, around- the-island, and adventure-style races with half the normal crew size, with owners enjoying a “dream circuit” of events that tie into regional “classic” races that everyone aspires to sail in.

Now is the Time
The J/121 is the answer for those seeking a boat that offers compelling performance with less crew, all-around sailing versatility, low maintenance, and is fully ocean capable to be delivered on its own bottom anywhere.  The J/121 is a return to the shared adventure, sail-with-friends style of sailing and racing that’s more memorable and meaningful than the specialized, athletic W/L racing that’s succeeded mostly in establishing a pecking order that’s impossible to crack.  This design hits all the hot buttons for J/sailors, but will appeal to new entrants to the sport who are drawn to turnkey adventure sailing with a pre-planned event schedule and readily available event support only the J/Network can provide.

 

J/121 Open Course Racing Announcement!
J/121 Open Course racing combines the best of distance and buoy racing and packs it into a half-day time-slot to better fit people’s time-crunched schedules.  Sailors are trending towards events that offer more variety and adventure, and not just 4-leg, windward-leeward W-4 courses.  Open Course doesn’t eliminate windward/leeward sailing, it simply expands it to include other points of sail on a stretched-out track that rewards navigation, weather routing and strategy as much as it does boat-handling, racing rules and tactics.

Three Bridge Fiasco course on San Francisco BayThe Open Course format and scoring can be applied over any length course, including overnight races. For distance day-racing, the idea is to sail within sight and access to the shoreline including, where possible, courses around islands and other interesting coastal features.  The starting line is set to suit the course and NOT always upwind.  One could start on a beam-reach sprint leg with Code 0’s flying like the America’s Cup.  An example at right is the famous Three-Bridge Fiasco course on San Francisco Bay- an event that regularly attracts 300+ boats.

In a shift from traditional scoring, every race is 5-6 races in one, with incentives built in for great performances during the race.  The overall race has its normal placings (1st, 2nd, 3rd, etc.), but each leg has its own elapsed time trial, providing an opportunity for any team to pick up bonus points for having won a leg, even if they happen to be deep in the fleet at the time.  One leg of each race is additionally designated as the SPEED RECORD leg where the boat with the top recorded speed (as documented in the satellite GPS race tracker) is rewarded.  The idea is to acknowledge and reward highlights teams have during a race - highlights that might not otherwise show up on a normal score.  This incentive-based scoring system can easily be expanded in a fun way to encourage the development of other offshore skills in preparation for an upcoming signature offshore event.

Open Course racing is inspired by and tailor-made for the J/121, the newest J/Boats design that’s optimized for half the normal number of crew, and with the hull form, stability and sail plan perfectly suited for all-points, open style sailing.

Hi Tech Engineering & Construction

Symetrix hullplugThe J/121 hull plug construction was done by Symmetrix Composite Tooling in Bristol, Rhode Island.  Symmetrix is the most advanced precision tooling company in New England and is carving both the J/121 hull and deck plugs using the state-of-the-art CMS Poseidon 5-axis Machining Center located within their impressive tooling facility just a few hundred yards up the road from the CCFC factory.

This machine is like a building within a building, equivalent in size to four or five large garage bays stacked end to end with a perfectly level and polished cement floor.  The overhead computer controlled universal robotic cutter head runs down calibrated tracks on top of the side walls from one end to the other and can reach almost anywhere within the space. The large format CNC machining is optimized for durability, reliability and precision machining of advanced composite materials. It never compromises rigidity or stability over an impressively large work envelope. Further improving its overall structural stability, Poseidon’s A & C axis are equipped with a pneumatic breaking system, which locks either or both the A or C axis when their interpolated movement is not required, resulting in greater 3 axis rigidity. The CMS Machining Center at Symmetrix delivers the tight tolerance needed for aerospace, transportation, alternative energy, marine, art and architecture. In fact, the machining center was certified to an overall volumetric tolerance of 0.1mm or .004”.

X= 26m /83.3’ Y=6.2m /20.4’ Z=3m /9.9’ A= +/-120° C= +/- 270°

Symmetrix engineers analyze final 3D design models provided by J/Boats using Siemens NX11 CAD/CAM software and will run a series of simulations to arrive at final machining instructions for the 5-axis milling machine.   The Siemens NX11

 
software is a quantum leap forward in delivering tooling not just quickly, but also accurately. Similarly used at companies like Boeing, SpaceX, and MacDonnell Douglas, NX10 gives Symmetrix complete surface model control and simulation in either 3+2 optimized or full 5-axis machining instruction. Like Symmetrix, NX10 has been tested and used across a wide range of industries.  The combination can produce outputs even seasoned craftsmen can’t achieve. Whether it’s curved composite roof columns or the exacting requirements of an America’s Cup entrant, it can achieve tolerance within millimeters over a 26 meter surface and in a fraction of the time.

Symetrix sideThen the exciting part starts.  First the steel backbone frame with foam blocking is milled to within an inch or two of the final plug surface (all milled foam is recycled, BTW) and then the plug and foam are supported by fiberglass/epoxy reinforcement, and then an epoxy milling paste is applied over the glass.  The part returns to the milling machine for a second and final precision machining operation to take it to the final surface.  Hand sanding to 800 grit and buffing to a mirror shine then completes the effort.

From initial steel framing construction, to precision milling operations, to the final polishing the process to build a complete mirror finish hull plug/pattern will take just 7 short weeks. Production molds will then be constructed in January at CCFC and from there J/121 project development will accelerate through the winter and into spring.

By mid-December the Symettrix team completed the hull plug, with the majority of the actual CNC 5-axis machining taking place in the "rough cut" over a 2.5 day period!  Here is the amazing production video of that process, watch it here on YouTube.com:

Meet the J/121

Creating the best short-handed J ever starts with a hull shape that excels on all points of sail, particularly reaching.  Most classic distance races have a beat/reach/run ratio around 15%/60%/25%.  Straight-line speed is the name of the game and is achieved by having a low drag, efficient hull with high form stability and exceptional balance.  Add to this a highly engineered carbon rig package, an L- shaped low VCG keel, infused composite construction, and a water-ballast assist system that adds nearly 400 kilos (4 big guys) of crew weight to the rail and you have the J/121.

Simplified Sail-Handling
Handling a 40 footer with 5 or fewer crew requires a rig, sail and deck plan that simplifies sail handling. New technology developed for the Vendee Globe, Volvo Race and other extreme offshore sailing events, is trickling down faster than ever, particularly in new furling systems.  The J/121 class sail inventory features an AP furling J1 jib, a hoistable furling J4 inside the forestay, a furling Code Zero with top-down furler flown from the bowsprit, and an all-purpose A2 asymmetric spinnaker with either top-down furler or snuffer.  Each headsail is dedicated to its own furler, meaning less hands on the foredeck and more compact sail stowage below.  Combine that with a mainsail on slides that can be quickly adjusted to three different sizes (via a double reef system) and you have a versatile, manageable sail combination across most wind/sea conditions.

J121 deckVersatile, Ergonomic Cockpit
J/121’s ergonomic cockpit builds upon the award-winning J/111 design, with excellent working space, protection from the elements behind a soft dodger or hard canopy, and exceptional twin steering stations that allow the driver to straddle the wheel and reach all the mainsail controls while driving.  Clean line sights forward from the helm and trimming positions provide immediate gear-changing input.

 

A 3D jib lead system using floating trim rings allows nearly infinite placement of the jib clew (crucial for reaching) without the friction normally associated with in-hauling or out-hauling from a track-mounted jib car.  The hydraulic backstay system features a remote panel with release buttons port and starboard.  Water ballast controls are cockpit led so that the on-deck crew can easily manage the transfer or dumping of the tank(s).  Electric primary and secondary winches are available (and class legal) for push button trimming ease.

J121 interiorSpacious, Open Interior
When the team needs moments of respite, the J/121 interior is clean and simple but beautifully finished with a feeling of space not often found in fast offshore racers. The interior is offered in Herreshoff classic white with varnished trim accents.  For the “armchair navigator,” both onshore and offshore, there is no substitute for a comfortable nav station to house all of today’s modern electronics and entertainment systems.  The L-shaped galley features a stove, SS sink, and large icebox with storage drawers and shelves.  Amidships settees are full-length for sleeping and offered in over/under configuration.  The head is aft to starboard near the companionway, perfect for offshore sailing.  Forward of the main bulkhead is sail storage with an option for a removable V-berth.
