Guest Posted November 1, 2011 Share Posted November 1, 2011 The Volvo open 70's can be a very technical boat if you dont know much about them or the terminology. For those of you that dont know much about boats, heres a break down for you of what makes up one of the 70 footers. Mainsail Flown behind the mast, the mainsail is the primary sail on the boat and the only one permanently in use. Jibs/Genoas Two sailing terms for the sails flown at the front of the boat when the boat is sailing towards the wind. Each boat might carry several different sizes and weights of these sails to be used in different wind strengths and angles. Gennaker The sailing term for the sails used when the wind is coming from the side of the boat. Each boat might carry several different sizes and weights of these sails to be used in different wind strengths and angles. Spinnakers These are the sails used when the wind is coming from behind the boat. Each boat might carry several different sizes and weights of these sails to be used in different wind strengths and angles. Mast The towering vertical carbon tube from which all the boat’s sails are flown. Sometimes also referred to as “the rig”. Boom A horizontal carbon tube which attaches the bottom edge of the mainsail to the mast and enables the crew to control the mainsail via the mainsheet. Shrouds A fixed matrix of strong support lines running from the deck to the top of the mast to help keep it upright. Spreaders Pairs of strong carbon struts projecting sideways from the mast and connected to the shrouds to add extra support to the mast. Runners Strong adjustable support lines running from the stern of the boat to the mast to help keep it upright. Stern The sailing term for the back of the boat. Bow The sailing term for the front of the boat. Bowsprit A carbon strut projecting from the bow of the boat from which sails are flown. Guardrails A wire safety “fence” around the boat to prevent equipment and sailors being washed overboard. Pulpit A strong carbon frame at the bow of the boat to which the guardrails are attached. Pushpits Strong carbon frames on each corner of the stern of the boat to which the guardrails are attached. Foredeck The sailing term for the work surface between the mast and the bow.Cockpit A large slightly recessed area in the back half of the boat, the Cockpit is the main work area of the boat where all of the ropes used to hoist and trim the sails are fed to. Daggerboards Two long fins on either side of the boat which can be projected through the hull and into the water to help stop the boat sliding sideways. Canting Keel A huge underwater lead counterweight (Bulb) on the end of a long steel blade (Fin) which can be swung (canted) to either side of the boat to balance it against the force of the wind. Communications Dome A large watertight container located on the back of the boat containing the cluster of antennas used to transmit and receive data from the boat. Navigation Station The area of the boat below decks containing the bank of computers and other technology used by the Navigator. Pedestal Winches Located in the Cockpit, Pedestal Winches are large mechanical devices comprising two armoperated rotating levers and sophisticated of gears. Sheets In the world of sailing, the ropes used to control the sails are called “sheets.” For example the “mainsheet” is used to control the mainsail, “jib sheets” control the jib, there are “genoa sheets” for the genoa and “spinnaker sheets” for the spinnaker. Halyards The sailing terms for the long ropes which are used to hoist the boat’s sails. Halyards run from the Cockpit, inside the mast to the top and back down to the deck.

Guest Posted November 1, 2011 Share Posted November 1, 2011 Some more info about the boats The Volvo Open 70 yacht design is the world’s fastest monohull. It is a state-of-the-art craft incorporating leading edge performance technology and safety. During the Volvo Ocean Race 2005-06, the Dutch entry, ABN AMRO TWO, designed by Juan Kouyoumdjian, smashed the World Sailing Speed Record for distance covered by a monohull within 24 hours when they achieved 562.96 nautical miles. In the next edition in 2008-09, Ericsson 4, the overall winner, skippered by Torben Grael (BRA), broke record during Leg 1 from Alicante to Cape Town, on another Juan Kouyoumdjian designed Volvo Open 70. The team sailed 596.6nm (equivalent to 1104.9 km) in one day, at an average speed of 24.85 knots. Ericsson 4’s elapsed time for the 37,000 nm 2008-09 race was 127 days, 7 hours, 46 minutes and 17 seconds. The Volvo Open 70s are able to cant the entire keel 40 degrees to the windward side. This produces tremendous stability but allows the boat to only weigh 14,500kg. Stability of the Volvo Open 70 is further enhanced by the use of composite rigging, rather than stainless steel rods, which reduces the weight of the rig. Volvo Open 70 Specifications Length overall 21.5m (70′) Beam 5.7m (18′9") Draft 4.5m (14′9) Mainsail area 175m² (1883,7 ft²) Spinnaker area 500m² (5381,9 ft²) Mast height 31.5m (103,3 ft) Weight overall 14,500kg (14.5 tonnes) Height of the mast: 31.5m or 103.3ft above water Overall boat length: 21.5m or 70ft The mast: 31.5m or 103.3ft above water The height of the mast is as tall as Christ the Redeemer, in Rio de Janerio, Brazil, (excluding pedestal). Boat length: 21.5m or 70ft The overall boat length is 1m more than two double decker buses. The overall boat length is 1m taller than the height of the Great Sphinx of Giza. Space: Two metres of space per person (equivalent to living in a phone box made of carbon fibre). Speed: The Volvo Open 70 can exceed speeds of 40 knots (45,98mph/ 74kmh). The Volvo Open 70 is faster than a greyhound. Sails: Largest spinnaker on a Volvo Open 70 is 500 m² The largest spinnaker onboard is the same as two tennis courts playing area.Number of sails per boat for the race: 17 sails and two In-Port spinnakers, with the exception of storm sails. Number of sails per Leg: 7 sails and 3 storm sails. Cameras: Seven on board including five fixed – able to look forwards, backwards and through 360 degrees, one looking below deck, two handheld operated by the onboard Media Crew Member. The keel and bulb weigh a maximum of 7,400kg The keel and bulb weigh the same as 7 rhinos The keel and bulb weigh the same as 2 African elephants The counterweight produced by the canting keel equates to 70 people sitting on the side of the boat. Volvo Open 70 weighs: A total of 14.5 tonnes, with a 4.5 metre draft and 5.7 metre beam. It can reach speeds of more than 40 knots during the race. The Volvo Open 70 weighs the same as 3 African elephants The Volvo Open 70 weighs the same as 6 great white sharks The hull and rigging: Of a Volvo Open 70 equal the weight of 125 red kangaroos, the largest marsupials on the planet or 32 Eastern Lowland gorillas, the largest primates on the planet.

Grinna 2 Posted November 1, 2011 Share Posted November 1, 2011 Why have they compared weights of parts of the boats to things that nobody has any idea about?? The weight of the hull and rig is equal to the weight of 125 red kangaroos or 32 eastern lowland gorillas????? Sure, I'll nip out the back and stack 32 eastern lowland gorillas on top of one another and lift it to see how heavy that is. Yeah, right!! Link to post Share on other sites
John B 106 Posted November 1, 2011 Share Posted November 1, 2011 Fancy leaving out stays, or don't they have em on them things. Link to post Share on other sites
Richard2249 5 Posted November 2, 2011 Share Posted November 2, 2011 What's more interesting to me is the fatter bow approach on Abu Dhabi, I think like that Mini 6.5 scow the idea is to increase the prismatic coefficient on a shallow hull which gives a great reaching boat. I wonder if this boat will be a bit of a breakthrough just like the ABN Juan K design the first time round. Still, I'm hoping that Camper has the goods. Link to post Share on other sites
candela 0 Posted November 3, 2011 Share Posted November 3, 2011 Can anyone tell me how they manage the canting keel in regards to the engine?? I know it is a diesel engine with hydraulics but they cant be running the engine all the time. Is it battery operated and engine just works as a generator?? Do they just start the engine when its needed?? Link to post Share on other sites

Do they just start the engine when its needed?? Its hydraulic so im guessing they have a bit of reserve and if they are short tacking i rekon they probably just drop it down before tacking, but yeah the engines just start when needed, probably when the pressure drops below a preset level id guess Link to post Share on other sites

Richard & John B -- John - all the rigging is 'string-stuff' - doesn't weigh very much at all. Richard - me thinks you should very carefully check-ou the bows on the other 'wo-wo's - am sure you'll see that Abu Dhabi isn't the only one with a 'fat-bow'. Take a real close look & you'll see it.
