B & R rig question- Thread starter DougM
- Start date Jul 24, 2020
- Forums for All Owners
- Ask All Sailors
Just curious: Some Hunter sailboats have been marketed with B & R rigs, and now the new Beneteau 30.1 appears to have the same. Typically the aft support comes from the swept back spreaders bringing the shrouds further back In the sailplan. I raced MC scows with a similar setup so I know the rig works. My question, not that I would attempt it, is would the mast on a Beneteau 323 or similar boat that already has swept back spreaders stand up without the split backstays? ( assuming no change in the shroud attachment points) It would probably stand up until a sail was hoisted, then all bets are off. I can's speak for all Hunter or the Bene 323 s but it would not be wise on my H26. My mast is attached to the boat via a hinged mast foot. So.... it would most likely rip the foot out and fall forward anytime the wind was abaft the beam. FastOlson said: the more-complex B&R will cost about 3 times what a conventional single or double spreader rig will cost. Click to expand The "backstayless" B&R has longer spreaders and more backsweep on the spreaders to allow the headstay to be tight when there is no main.. The mainsail when trimmed (with a traveler) and within a couple feet of centerline adds a LOT of tension to the headstay and will usually keep the mast from falling forward.. but don't try it!! Had a backstay fail on a friend's O'Day 29 and we sailed back with a reefed genoa and full main .. We did use the spin halyard as a temp backstay after a bit, but the rig was stable with the main sheeted in .. If ya have a good tight topping lift, that, with no main, and the traveler sheeted n tight on center will keep the rig from falling forward.. Again, don't try that unless ya have to.. DayDreamer41I would not recommend mounting a mast that was not designed for a particular vessel. @FastOlson I think you may have talked to a rigger who either loves to overcharge or has little to no experience with the B&R rigging. While eliminating the back stay or stays the B&R rig adds (4) diagonals which each have turn buckles, but the diagonals are only 3/16 cable on our 41 DS. As for removal of sail oriented line from the cockpit I think not, the traveler is overhead with the control from the helm, the jib sheets are led through block and winches also which can be controlled from the helm and other lines are on the cabin top and are controlled from the cockpit. The B&R rig sets the supports 120* apart allowing for a tripod arrangement, the diagonals minimize mast pumping as compared to conventional rigs.

I get the info from a professional rigger with decades in the business. The $ difference is not absolute, and you might find a deal, but sometimes owners of boats with this setup are * taken aback by this. Dealers are loathe to discuss it, for obvious reasons. Click to expand Note that a significant part of the cost of replacing a B&R rig is involved in tuning a lot of different parts to the proper pre-load, and this adds time & cost to the process -- as it does for any complicated discontinuous rig. All quite do-able, but not at the price many sailors might assume if they are not familiar with it. OTOH, a simple single-spreader rig is less expensive to build, and easier to tune. The B&R rig lacks a backstay to accomodate a large roach main sail to provide power. The system design utilizes a small head sail for balance. This is not your traditional rig. Rigs are engineered and it's best not to re-invent them. But lot's of dingies's have swept back spreaders and no backstays without being "B&R." My Bandit 15 was just one. I would argue that a sail plan with a large roachy main and small jib is traditional. The mast head rig with its large jibs was an anomaly created by a sail racing rule - IOR. Crazy Dave CondonI will speak in layman’s terms. First, I knew many in this industry as a dealer to include warren Luhrs and the two owners of B & R. Before the B & R rigs, there were many day sailor boats with swept back spreaders with no back stays which worked. True for the B& R Rig but included reverse triangle stays. What you got was a smaller jib, larger mainsail vs a traditional main and no backstay. It allowed more room in the cockpit. Warren Luhrs went with that design first designed for a couple test boats and later individually for each model and tested before any boat was sold. I was also aware there were no design failures but yes to improper rigging, maintenance, accidents, etc... As for tuning, yes it took up to anhour longer to tune once you knew the hang of it with a new boat but was also my policy to test sail each boat and correcting any deficiencies before delivery. As for technology, equipment changes which is a plus to include in mast roller furling, walk thru transoms with fold down boarding ladders, electronics, comfort, stern rail seats, etc which most sailors appreciate are generally accepted by the cruising sailors. One factor not mentioned is the room allowed in the cockpit. Yes things change but this is what cruising was about comfort. Yes there are the racing sailors and that was addressed as well in technology and the newer design sails is an example I could go on but my customers appreciated the B&R Rig. Yes there is some disagreement but overall the B&R Rig was accepted - This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

Inside the America’s Cup: A Closer Look at AC75 Masts & RiggingPhoto: America’s Cup As the Round Robins progress and Barcelona delivers, the AC75 fleet is looking fast. Whether it’s the return of the cyclors, enhanced foil designs, aero improvements, or more advanced control systems, a range of technical innovations are frequently cited as the reason for driving this impressive performance. In this respect, one area that may have received less attention is the rig and rigging design. Yet, especially since the arrival of composite materials in the America’s Cup, it’s an area that has had a formative impact on how things play out on the water. Southern Spars has played a leading role since entering the America’s Cup fold in 1995, with the supply of Team New Zealand’s innovative high-performance carbon mast that took them to a historic victory. Southern Spars’ sister company, Future Fibres, is also increasingly central to the trajectory of composite innovation in the Cup. Class Rules AC75 class rules specify several key one design aspects of mast design and construction. They stipulate the shape (D-section) and the size (within a tolerance) of the mast tube. The Rule also dictates the required carbon fibre specification, including the fibre modulus, areal weight, and resin content. Additionally, the geometry and materials of the fittings, such as shrouds and spreaders, mast rotation restriction to 45°, and the height of the mast rotation ball relative to the waterline are all defined by the rule. Mast Rotation Through controlling the 45° mast rotation, each team has at their disposal a mechanism to access enhanced power and performance. All AC37 participants have selected North Sails as their best option such is the compelling performance of the North Sails Helix structured luff technology, which has redefined what a sail can deliver—its internal structure enhancing power potential by controlling the loads through the sail structure, delivering a proactive, positive sail shape. With a mast designed to react to the conditions by rotating to the exact degree needed to exploit every breath of wind and realise the sail shape intended by the team’s sail designers, the benefits of Helix are taken to the extreme. You could almost say that the masts on AC75s have become part of the sail, or the other way around, and it definitely feels like the lines are blurring between the essential elements of the engine above deck. Thickness & Stiffness Another way masts influence sail shape is, of course, mast bend. This is the stand-out area where teams can differentiate their masts to influence performance. While the D-spar minimum laminate and core details are specified under AC37 class rules, teams are free to add more laminate if they choose to. There are always weight to performance trade-offs, but there is scope within the teams to increase the overall stiffness of the mast, or to alter the deflection response—optimising it to suit the desired degree of mast bend that the team’s sail designers are calling for. No Backstay While the rigging for AC37 is a fully one design “supplied” component from by Future Fibres, identical onboard each AC75, some significant changes have been made to the rigging packages since the 36th America’s Cup. One talking point is the elimination of the backstay, which also has a knock-on effect on the wider engine above deck. Mast bend, which would conventionally be influenced by backstay control, is now almost solely manged by sail controls. Another knock-on effect is escalating load through the shrouds, which has required the cap shrouds to be enlarged and jib locks to be upgraded from 5t to 8t for this edition of the cup. One constant though, and as per the AC36 rule, the Future Fibres rigging packages are equipped with integrated fibre optic load monitoring, for performance analysis and to keep an eye on loading limits. Looking Ahead Beyond the talking points we have summarised here – luff tracks, batten stiffness, batten locations, halyard locks and mainsail controls – all sit within the remit of team designers. It remains to be seen which technical factors will rise to the surface during the 37th America’s Cup, but it is a safe bet that ripple effects from technological choices and innovations will be felt around the wider sailing landscape in the coming years. General Manager of Southern Spars, Mark Hauser comments, “We are immensely proud of our close partnerships with the teams and together we commit ourselves entirely to the pursuit of excellence.

Characteristics of the B&R rig include swept spreaders (2) and reverse-diagonal shrouds (1). The B&R rig is a variant of the Bermuda sailboat rig, designed and patented by Swedish aeronautical engineers Lars Bergström and Sven Ridder. [1] It employs swept spreaders that are usually angled aft, together with "stays" running diagonally downward from the tip of the spreaders to the attachment of ...
The B&R rig has 30-degree swept spreaders, creating 120 degrees between each rigging point. The result is a tripod arrangement, used for years to support huge radio towers, that has excellent strength for sailboat rigs.
The B & R rig utilizes 30 degree swept-back spreaders creating 120 degrees between each rigging point. This tripod arrangement is similar to the huge radio towers you see from the highways. Claimed benefits ( by Hunter) of this rig include: The strength is increased because the loading to the rig itself is decreased.

B & R rigging systems are on boats the world over. World cruisers and racers, OSTAR boats, 2 ton, 1 ton, 1/2 ton, 1/4 ton boats and multihulls. Wherever one finds sailors who want performance and reliability. The basic difference between a B & R rig and a conventional rig lies in the B & R's use of swept back spreaders and diagonals.
Why would you want a mast without a backstay? The what, how and why of this distinctive Hunter feature.
The fore-and-aft rig, however, has a lot of variations. The three main sail rigs are: Bermuda rig - most used - has a three-sided (triangular) mainsail. Gaff rig - has a four-sided mainsail, the head of the mainsail is guided by a gaff. Lateen rig - has a three-sided (triangular) mainsail on a long yard.
The team of Sven-Olof Ridder and Lars Bergström are responcible for a number of innovations in the world of sailing, including the Windex (masthead wind indicator) and the B&R rig, which has been adopted by many builders to this day. They formed their first company, RADAB, an acronym for research and development, AB, in 1964 (with Harald Undén) while the two were engineering students at the ...
Count the number of turns on the turnbuckles. You will start to see the prebend appear in the mast. Pull a string from the top to the bottom. Tighten the diagonals until the distance from the string back to the center of the bend is about 1% of the total length of the mast. You can now have the mast put back on.

The complex B&R rig, with its swept-back spreaders and diamond shrouds, is also a headache for some owners.

Hunter 310 Ottawa. Jul 1, 2021. #2. Hi Gary. I have wrestled with tuning the B&R rig for the past five years. I have found that at about 10 - 12% the mast is well supported and the leeward shrouds remain under tension in a 15 knot wind. There needs to be some fore - aft bend which ideally matches the cut of the sail's luff.
The Hunter 28.5 is rigged as a sloop with a split backstay and a B&R rig, which means that it has no backstay and uses swept-back spreaders to support the mast. The mast is deck-stepped and has a height of 12.6m (41.33 ft) above the waterline. The sail area is 36.9m² (397 sq ft), with a mainsail of 16m² (172 sq ft) and a genoa of 21m² (226 ...

No dinghies have a backstay and the mast is sufficiently supported. The B&R is a well tested rig and it is just not having a backstay feels wrong if you are used to one. The Hunter was designed with this in mind and as a cruising boat it is very unlikely to have high loadings on a run anyway. 21 May 2019. #10.

While the B&R rig worked acceptably to support the mast (if you accept main sail chafe when sailing down wind) on some boats that also used backstays, the rig design does have one major drawback.

June 17, 2024. Sailboats are powered by sails using the force of the wind. They are also referred to as sailing dinghies, boats, and yachts, depending on their size. Sailboats range in size, from lightweight dinghies like the Optimist dinghy (7'9") all the way up to mega yachts over 200 feet long. The length is often abbreviated as LOA (length ...
