The Volvo Ocean 65 (also abbreviated VOR65 ) is a class of sailboat that was developed for the Volvo Ocean Race and used there in the 2014/15 and 2017/18 competitions. With this class, unit boats were driven for the first time in the Volvo Ocean Race. For the regatta planned for 2020, the class for the high seas routes is to be replaced by sailing yachts on hydrofoils , and for the in-port races by catamarans .
Reason for the new class
The draft followed the objective of achieving a cost reduction compared to the previous design class, Volvo Open 70 . a. through the uniform production by the organizer. The class was presented by the then managing director of the regatta organizer, Knut Frostad, on June 28, 2012 after a stage of the Volvo Ocean Race 2011/12. Frostad assumed future total participation costs of 15 million euros, of which 4.5 million would be for the boat and the sails. In contrast, participation on the basis of the Volvo Open 70 would have cost 30–40 million euros. It was hoped that this would increase the number of participants to 8 to 10 boats. In 2014, eight teams started with the new unit boats; In 2017 there were seven.
In addition, the individual optimizations of the Volvo Open 70 had led to increasing safety concerns. The exhaustion of the class regulations resulted in increased damage, especially in the hull and rig.
The Volvo Ocean Race 65 (VOR65) was first developed by Farr Yacht Design as a one-design boat for the Volvo Ocean Race . The boats have been built centrally for all participants since the Volvo Ocean Race 2014–2015 . The previous version of the boat was the five- foot (about 1.5 meters) longer Volvo Open 70 (VOR70) . The Volvo Ocean Race 65 is being built in four different shipyards located in four countries (Green Marine United Kingdom , Decision Switzerland , Persico Italy and Multiplast France ). According to the organizers of the Volvo Ocean Race, three reasons led to the development of the VOR65:
- The speed-determining parameters (length, weight, sail size) of the boats should be standardized. The fastest design that complies with the rules was chosen.
- The boat should be built with the world's best technology and as light as possible.
- The design of the boat should be adapted to the requirements of the crew.
In contrast to the previous version, the VOR65 has undergone some innovative changes. For example, the water ballast carried can now be distributed to different ballast tanks. The keel was also enlarged from 4.5 meters to 4.7 meters in draft. Some of the security and structural changes have also been made. The VOR65 now has eight instead of four bulkheads.
Since the boats are to be used several times, they were prepared after the Volvo Ocean Race 2014-2015 in an extensive re-fit program for the subsequent Volvo Ocean Race 2017-2018 . In addition, a yacht was rebuilt for the 2017/18 race.
features
The design comes from Bruce Farr and is largely based on the Volvo Open 70.
All of the VOR65 hulls are built in segments by a consortium of four companies. Decision ( Switzerland ) produces the bulkheads and structural constructions. At the same time, the fuselage and the associated longitudinal stiffeners are being manufactured by Persico ( Italy ). The deck is built and equipped by Multiplast ( France ). The marriage of the individual parts to the finished boat takes place at Green Marine ( United Kingdom ). She coordinates the respective construction and is also the contact person and support company for the participating teams.
The boats are made of composite construction. Most of the parts are made entirely from carbon fibers . The fuselage is manufactured in sandwich construction. This construction creates a very light and also heavy-duty sailing yacht.
The bow of the VOR65 has a negative stern, which is rare for monohulls. This is to ensure that the fuselage no longer moves over the waves, but rather through them. Amidships in front of the bow is a 1.5 meter long, permanently installed boom to which, among other things, the gennaker is attached.
The underwater hull is designed completely flat over almost the entire hull from the bow to the stern. This should improve the gliding properties on open and downwind courses. This fact is mainly due to the route to the east typical of the Volvo Ocean Race and the westerly winds that occur in the Southern Ocean .
The stern is flat and the cockpit is open to the rear. This promotes the rapid drainage of taken over water.
The keel, which can be swiveled up to 40 ° on both sides, serves as an underwater weight. This gives the VOR65 a water depth of 4.78 meters (not inclined).
The boat can get additional righting moment through water ballast tanks installed in the hull. For this purpose, 800 liters can be pumped to the side of the cockpit and / or 1200 liters of water into a tank located in front of the mast.

Rigging, rigging, sails
Rig
The rig of the VOR65, like the hull, is manufactured identically for all teams and provided by the organizer or the manufacturer (Southern Spars). It was developed for the Volvo Ocean Race and designed according to the requirements. The sloop rigged mast is made of carbon fiber and is 28.4 meters high.
The tree has a total length of 7.68 meters and is also made of carbon fibers. The rig is attached with nine separate shrouds and has a minimum breaking load of 26 tons.
sail
Each VOR65 team is provided with a total of 12 sails, whereby only eight of these may be carried per stage. The main sail manufacturer of the Volvo Ocean Race is North Sails US . Almost all of the sails are in modern 3Di technology from aramid - or Dyneemafasern made.
The following sails are provided to the teams:
| Surname | Size [m²] | material | Usage type | Details |
|---|---|---|---|---|
| Mainsail / mainsail | 161.4 | 3Di, 270,000 dpi | All courses | 3 reefing points / 6 battens |

| Masthead Code 0 (MHO) | 305 | 3Di 13600dpi | Light wind sails (0-6 ktn) | also used with moderate winds or strong breeze (downwind) |
| Pre-Race J4 / storm jib | 29.7 | spectra S 395 | from +35 ct | Storm jib or used as a staysail |
Outfitter
The sails come from North Sails , mast , boom and standing rigging from Southern Spars Composite Rigging and North Technology Group. Inmarsat is responsible for the radio technology . Gottifredi Maffioli supplies the 3,000 m running goods , Harken supplies the winches and Equiplite supplies the blocks. The boat electrics come from Mastervolt. Cariboni manufactures the swivel keel mechanics, Iron Brothers the keel and bomb. The diesel engine for port maneuvers is a Volvo Penta D2-75.

Boats
The boats are built by the regatta organizer at Farr and then given to the teams. The construction of a VOR65 takes seven months and takes around 36,000 man hours. 120 boat builders and 70 suppliers are involved.
A total of nine yachts were built. Seven boats, which already took part in the regatta of 2014/15, were overhauled for an estimated 1 million euros and used again in the regatta of 2017/18. In addition, there was a new VOR65 building for the 2017/18 race. For 2017/18, the yachts received a 500 watt hydrogen generator to reduce emissions and wear and tear on the diesel generator manufactured by Volvo Penta Marine.

criticism
The design was largely positively received by experienced Volvo Ocean Race participants. Grant Dalton, who has already won the regatta, said the draft addresses the real issue of the sport at the moment, namely the absurdly high cost.
Criticism came from fans and especially from yacht designer Juan Kouyoumdjian , whose boats had won the three previous editions of the regatta. He disapproved of the move to the unit boat race. The allegation that the Volvo Open 70 yachts are too expensive is not true. His ships would have been in the cost range of 5 million euros. Whatever you do, the financially best equipped team will always win (“the richest will always win”). He had already been asked whether he could optimize a Volvo Ocean 65 for a possible participant.
