Why do the Ocean Race sailboats look so different? What to know about IMOCA vessels

The Ocean Race features two fleets of high-performance racing yachts, both capable of speeds high enough to travel 600 nautical miles or more in 24 hours under the right conditions.

For the first time in the history of The Ocean Race, the teams are racing 60-foot IMOCA class vessels in pursuit of the Ocean Race Trophy, crewed by teams of four sailors and one onboard reporter.

The 65-foot VO65 Class is racing for The Ocean Race VO65 Sprint Cup over three legs: Leg 1 from Alicante, Spain to Cabo Verde, Leg 6 from Aarhus, Denmark to The Hague in the Netherlands, and Leg 7 from The Hague to Genova, Italy.

How are IMOCA 60 boats sailed?

The IMOCA Class uses a “development design” rule which allows the designers to experiment with hull and sail shapes within set parameters. However, masts, booms and standing rigging are one-design.

Since 2015, the class rules have also allowed the use of retractable underwater foils which further boost performance by lifting the boat partially out of the water, at times allowing the boat to move faster than the recorded wind speed.

While some teams are using pre-existing vessels for the race, Newport-based 11th Hour Racing took advantage of the development design condition to build a custom IMOCA designed specifically for a crew of four – a huge departure from rigging and control configurations geared towards solo racers, and one that allows the team to maximize performance and speed.

Their custom-built boat Malama features 22-foot retractable underwater foils, a three-ton canting keel, a 95-foot mast and has eight sails on board. So far, it has reached a top speed of 38 knots, or about 43 miles per hour.

The other four teams crewing IMOCAs are Team Malizia, GUYOT environnement-Team Europe, Biotherm Racing and Holcim PRB.

VO65s are racing over three legs for The Ocean Race VO65 Sprint Cup

The V065 fleet is built to a strict one-design rule, meaning the boats are identical in every way and evenly matched in terms of performance capability.

These boats are single-hull carbon construction yachts, raced by mixed-sex crews with a minimum of seven sailors, and are capable of racing up to 600 miles in a single day.

VO65 teams participating in The Ocean Race VO65 Sprint Cup are competing in the VO65 class in the in-port races scheduled in each city in addition to three stages of offshore racing from point to point:  Alicante, Spain to Cabo Verde; Aarhus, Denmark to The Hague, the Netherlands; and The Hague to Genova, Italy.
