Sailing Ratios

Classic yacht-design ratios worked out from the builder's published figures, each shown against the bands designers read it by.

Most builders publish a light displacement. The ratios were defined on a loaded boat, so every boat here reads a little lighter than a surveyor's figure would — all alike, which keeps them comparable.

Tanks

What the builder publishes about how fast, how strong and how much the boat carries.

About Boréal Yachts

Semi-custom

Breton builder of aluminium centreboard expedition sailboats founded in 2005 by navigator-designer Jean-François Delvoye — four models from the 13.9-metre Boréal 44.2 to the 21.6-metre Boréal 70, built at Minihy-Tréguier for the tropics and the high latitudes alike.

The first Boréal was born from the notebooks and sketchbooks Jean-François Delvoye kept on a six-year family voyage round the world with his wife and four children, aboard a 12-metre yacht he had built himself in his garden: from the Mediterranean to Cape Verde, Brazil and Argentina, ending with two years in the channels of Patagonia, asking every sailor they met what their boat lacked to be the best in the world. Back in France he drew the 15-metre aluminium Boréal 50 in every detail in 3D, meaning to build it and sail again; instead two yachts were sold before the prototype touched the water, and the company Boréal was created in 2005, a little by chance, with three experienced clients. In 2010 he joined forces with Jean-François Eeman, met on a pontoon in Ushuaia, for whose family the first Boréal 44 was built; when Eeman set off round the world again in 2020 on his Boréal 47, Eric Vautrin took the helm alongside Delvoye, who designs every boat and heads the design office while Vautrin looks after the clients. The Boréal 44, launched in 2009, was Yacht of the Year 2010 in France and in 2011 in the Netherlands; the Boréal 52 was European Yacht of the Year 2015 among bluewater cruisers; the Boréal 47, shown at Annapolis in 2017, was named Best Midsize Cruiser and overall Boat of the Year 2018; and the Boréal 47.2 won Voile Magazine's jury prize and European Yacht of the Year 2021 in the bluewater class.
