470 SPEED GUIDE BY SÎME FANTELA

Who sails the 470.

What does it take to be successful in the 470?

Who does what on the boat, what are the keys to rig set-up, what are the keys to rig tuning.

Upwind Sailing

Where does each person sit on a 470 in light air, what are the key changes in different conditions, what do you focus on when trimming the 470 main, what do you focus on when trimming the 470 jib, what are the key adjustments to make when wind and sea state increase, any other advice about gear changing in a 470, what's the typical conversation between 470 helm and crew.

Downwind Sailing

What 470 spinnaker would you recommend, where does each person sit in a 470 downwind, what are the key adjustments to make sailing downwind, what’s the most important thing about 470 trimming downwind in light air, what’s the most important thing about 470 trimming downwind in heavy air, what is a typical conversation downwind.

• What mode do we want to achieve (high and fast, or low and slow)?
• Is the Oscar flag up so we are allowed to pump?

Any special considerations to sail the 470 well downwind?

Boat Handling

Top three tips to starting a 470 well.

• Try to keep the flow on the rudder and centerboard as long as you can. Once you lose that, it can take some time to attach again.
• Always fight for space down to leeward. If you don't have enough, you're not going to survive the first 100 meters.
• Identify the last possible moment for a double tack. And whether you double-tack or not, know the right time for good acceleration and the right exit angle.

Any tips for 470 downspeed boat handling?

What is the most common mistake when tacking a 470, what does each person do in a tack, key tip for good light-air tacks in a 470, key tip for good heavy-air tacks, key tip for good light-air jibes, key tip for good heavy-air jibes, what’s the best way to set a 470 spinnaker who does what.

• Come in off the trapeze wire.
• Take the spinnaker tack out of the spinnaker bag with one hand, while pulling on the windward barber-hauler/twing with the other hand.
• Hook the pole to the sheet, topping lift, and mast - Jaws up!

What’s the key to a good 470 spinnaker takedown?

Personal Tip: We always have a windward takedown, because we have a storage bag on each side of the boat.

Doing a 720 penalty turn is slow. What are the keys to minimizing the pain?

How easily does the 470 broach or capsize, how do you recover from a 470 capsize, what are the most common boat helming mistakes made in the 470 class, any suggestions for drills to improve 470 boat handling.

2024 470 World Sailing Championship: Preview, schedule and athletes to watch

As the first major event of the year for the 470 class kicks off, here is everything you need to know ahead of World Championship, which begins on 24 February 

(Clive Mason/Getty Images)

Kicking off on 24 February, sailing ’s 470 class will see their first major event of the year: the 2024 World Championships.

A total of 63 International teams will drop into the waters of Arenal, Palma Spain for six days of head-to-head competition as the best sailors from across the globe fight for the world title.

The Championship also serves as the European and North American continental Olympic Qualifier , so stakes are high for those with their eyes on an Olympic quota.

The class, named 470 after the overall length of the boat being 4.70 metres, is a double-handed monohull dinghy with a mixed crew of one male and one female athlete in each rig.

President of the International 470 class and five-time Greek Olympian, Andreas Kosmatopoulos , said “We’re going to see a great competition in Palma.

“There are a number of Olympic qualifying spots being decided here, for Africa, South and North America, and one place for Europe. So the pressure is on, everyone will be at their peak and no one will be holding back.”

Since Tokyo 2020, the men’s and women’s 470 classes have merged into a mixed event, leaving athletes and spectators with one big question: who will be at the helm?

According to Kosmatopoulos, “there is obviously an element of strength and fitness required in the 470 but it is primarily a game of athletic chess. It doesn’t seem to matter who is on the rudder, who is steering the boat, what’s more important is the way that the helm and crew function together as a team. So with 470 Mixed we have the perfect test for men and women.”

As National Olympic Committees have the exclusive authority for the representation of their respective countries at the Olympic Games, athletes' participation at the Paris Games depends on their NOC selecting them to represent their delegation at Paris 2024

Athletes to Watch

Japan’s Keiju Okada and Miho Yoshioka are the current world title holders, who cruised their way to gold in the medal race at the 2023 World Championships in the Hague . The two competed separately at the Tokyo 2020 Olympics on their home turf, both having finished in seventh in their respective men’s and women’s classes.

Having joined forces to compete in the mixed class, the pair is strong across a range of conditions and are looking to defend their title in Palma.

Spain’s Jordi Xammar Hernandez and Nora Brugman will not only be competing on their home turf, but have consistently landed on the podium since the 470 class turned to the mixed format. They were runners up in both the 2022 and 2023 World Championship, and will be looking to top that this year.

Great Britain’s two-time Olympian Chris Grube and partner Vita Heathcote are strong contenders for the title, along with GB teammates Martin Wrigley and Bettine Harris .

France, Germany and People’s Republic of China could also be standouts among the competitive field in Spain.

Jordi Xammar and Nicolas Rodriguez Garcia-Paz of Team Spain compete in the Men's 470 class at the Tokyo 2020 Olympic Games.

Spinnaker Pump Halyard System

A 1:2 reverse purchase on the halyard allows the skipper to raise the spinnaker twice as fast. Pulling the pump handle .6 m (2 ft) off the cockpit floor raises the spinnaker 1.2 m (4 ft). A 1:5 shock-cord halyard take-up system automatically manages accumulating line during the rapid chute deployment.

The cascaded vang uses super strong single, double, and triple 16 mm blocks for a powerful 16:1 mechanical advantage. The skipper can play the vang from either side of the boat.

Two-Car Mainsheet

This fast-tacking two-car system halves the distance a single car would travel. The bridle and the 2:1 side-to-side traveler controls raise and lower the floating mainsheet block for perfect mainsail twist. Mainsheet tension tightens the leech and reduces twist.

Class History

The International 470, designed in 1963 by 505 sailor André Cornu, is a high-performance planing dinghy for both men and women. Responsive to weight placement, this two-person one-design is tactically demanding and requires fluid coordination between the skipper and crew. The 470 is easy to sail, but racing and flying the spinnaker from the trapeze provides additional challenges for sailors. The 470 made its Olympic debut in 1976, and in 1988 was selected for the Games first women's sailing event.

Hundreds of Sailors Ready to Race in the 60th Edition of Rolex Big Boat Series

One of the best sailboat racing venues in the world, iconic San Francisco Bay, is ready to turn it on for the 60th edition of the Rolex Big Boat Series at St. Francis Yacht Club, September 11-15, 2024. The most prestigious regatta on the West Coast drew 71 boats and nearly 700 sailors to the docks of St. Francis Yacht Club, to hear what classes will race for Rolexes and perpetual trophies on Wednesday night, and to start preparing for the first race on Thursday, September 12. With a strong turnout in one design classes and ORC divisions, organizers are thrilled to welcome members and guests to be a part of the action on the water and shoreside.  

“Having been involved in this epic West Coast regatta for some four decades, it is my honor and privilege as Commodore to welcome our members and guests to the 60th edition of the Rolex Big Boat Series,” said Chris Perkins, 2024 Commodore of St. Francis Yacht Club and a past winner of the event. “I wish the best of luck to our competitors who are here to compete in one of the world’s most spectacular racing venues. Sail fast and enjoy our outstanding hospitality.” 

Rolex Big Boat Series’ extensive history of champions is a tribute to the depth of talent that graces the event and this year, a solid fleet stacked with talented and tough competition is expected.  

“We have 30 J/105s starting again this year, which is great to see, and the ORC fleet is diverse and deep in talent with past winners returning to defend their titles,” says Felix Weidling, Race Director of St. Francis Yacht Club. “We always have our competitors’ best interests in mind and after taking in sailors’ feedback from last year, we continue to improve this important event which is a cornerstone of West Coast sailboat racing.” 

Perennial Rolex Big Boat winner in the J/105 class, Ryan Simmons and his well-seasoned team on Blackhawk are eager to see how the competition will play out in the competitive San Francisco-based J/105 fleet. Blackhawk took first in class in 2019, 2021 and 2023, and second in 2022. Simmons does not take for granted that his luck will bear out for another win, although he and his crew are talented enough—and hopeful.  

“We’re lucky, we have low turnover on our team—we’ve been sailing together a long time and it’s the big difference,” says Simmons. “Our competitive edge this year will be consistency. In the first two days of the regatta, you can’t lock in the win, but you can definitely take yourself out of contention, so sailing smart the first couple of days is key, but Saturday and Sunday are really where the championship will be won.” 

Hot to prevail against Blackhawk is NeNe , owned and skippered by Tim Russell who has played bridesmaid many times, often finishing in the top three. He’s currently leading the local J/105 fleet in the class championship series, making him a serious podium contender.  

“A first place on NeNe is alluding me!” says Russell. “You have to take chances and I usually approach every regatta being super conservative. On my starts I’m trying to win one end or the other and let our boat speed take care of itself and minimize mistakes, but in Big Boat you have to gamble.” 

Peter Wagner won last year’s ORC-C division on Skeleton Key, the J/111 he’s owned since 2015. Winner of the J/111 North Americans for two years in a row and St. Francis Yacht Club’s Sailor of the Year in 2023, Wagner is a tough act to follow. He’s been racing Rolex Big Boat Series for almost 25 years and is looking forward to the solid competition, great conditions and fun social gatherings. 

“It’s always one of the highlights of our season and certainly the highlight of racing on San Francisco Bay,” says Wagner. “In this particular event we’ve raced in various one design classes as well as ORR and now ORC and we’re really excited about the momentum around ORC. I think it will be a really competitive event. Some of the best, most reliable and most fun sailing conditions in the world are this time of year at this venue, the race management is second to none and the social side is always spectacular. There is always a great group of sailors that convenes around RBBS.”  

Other boats returning to defend their 2023 titles include the J/88 Pelagia owned and skippered by Christos Karamanolis, Cape 31 M2 owned and skippered by Marc McMorris, and J/109 Reverie, owned and skippered by John Arens.

TROPHIES & ROLEXES 

At the Competitors’ Briefing on Wednesday, September 11, at 1600, St. Francis Yacht Club announced which classes will be racing for the six perpetual trophies and two Rolex timepieces. 

J/105 

As the largest one-design fleet this year, the J/105s will compete for StFYC’s Commodore’s Cup. The top J/105 skipper will also receive a Rolex timepiece. 

ORC-A 

The St. Francis Perpetual Trophy, which was anonymously donated to StFYC in 1966 to encourage competition between large offshore racing yachts, will be presented to the winner of the ORC-A fleet. 

ORC-B 

The ORC-B division will be racing for the City of San Francisco Perpetual Trophy, which has been contested since 1968 and features one of the original spades from the opening of the Golden Gate Bridge. The winner of this division will also take home a coveted Rolex timepiece. 

ORC-C 

The Atlantic Perpetual Trophy, featuring a ship’s bell from the 1905 Transatlantic-record-breaking schooner Atlantic, will go to the winner of the ORC-C fleet. 

EXPRESS 37 

The Express 37s will race for the Keefe-Kilborn Perpetual Trophy, established in 1976 to honor the memory of late StFYC members Harold Keefe and Ray Kilborn, 

The Richard Rheem Perpetual Trophy, named for longtime StFYC member and skipper of Morning Star—the yacht that proudly broke the Transpac course record in 1949 and 1953—will go to the winner of the J/88 class. The PCYA Jesse L. Carr Perpetual Captain and Crew Trophy will go to the winner of the top J/88 finisher. 

CLASSICS  

The Classics will compete for the Classic Cup Perpetual Trophy. 

ADDITIONAL AWARDS 

All three ORC divisions will also be contesting the West Coast Championship. 

The Storm Trysail Team Trophy to the three-boat team who have entered and achieved the best score. The team must be comprised of one boat racing in an ORC class, one from a one-design class, and one from any other class. 

“I’m excited to lead the Rolex Big Boat Series in its 60th anniversary year,” says Susan Ruhne, who chairs the regatta and is the 2024 Rear Commodore of St. Francis Yacht Club. “The event is such an important part of the StFYC’s history and a favorite for so many sailors and spectators to experience. There is nothing like watching 70-plus boats on three race courses duke it out on San Francisco Bay, including the classic downwind run from the Golden Gate Bridge back to the club. I am also very proud that we continue to maintain Rolex Big Boat Series’ status as a Clean Regatta, a foundation of the event.” 

The 2024 Rolex Big Boat Series is targeting Platinum Level Clean Regatta status, the highest distinction from Sailors for the Sea. A pre-regatta volunteer event with the Parks Conservancy was held at Crissy Field on Wednesday morning. Organizers have taken efforts to remove all single-use plastic from the event, and competitors spectators are invited to meet local non-profits who serve as Sustainability Partners for the event. Sail to Shelter will be collecting old sails on site to recycle into shelter for humanitarian aid.  

Quantum Sails will be hosting Daily Weather Briefings every race day at 0730. All sailors are invited to tune in for the forecast from experts at Sailflow Weather and to hear local knowledge about San Francisco Bay conditions and currents. 

Racing is set to begin tomorrow, September 12, at 1100 local time for most classes and 1300 for the Classics.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)
