J/Boats 121 Overview

Known for its sailing races, the American shipyard introduced the 40-foot J121 in late 2017. In 2018 the J121 was named Yacht «of the Year in Britain» and the USA.

The exterior and interior design

Traditionally designed by the Johnston family, the J121 developed the success of the 120th model launched in 1995. With external similarities (overall length, width, draft), the J121 is a completely different boat. Displacement has been reduced by a ton, the waterline has been increased by a meter, the area of the sails (and these are the other sails) carried by the Carbon Rangout with removable boom. The cockpit became open, two handwheels appeared. The cockpit's gigarette wiring remained in the cockpit, but now it is more comfortable to work with this gear. The interior layout is similar: an L-shaped galley on the left, a navigating table on the right, and separate berths in the front of the cabin on the sides. The only cabin is aft. In 120, there was still a forward cabin, but in 121, it is no longer there, and the latrine is moved aft.

Amenities on board

Given the sporty nature of the boat, there are no facilities in the usual cruiser sense. But during an offshore race after watch you can cook and relax.


The monotype J121 is the first yacht of the shipyard with water ballast. There are two 380l tanks on board, which can be used to compensate for the lack of crew weight in the open, as the boat was planned to control a small (2-5 people) crew.

Swimming area

In the world of racing, 40 feet is a serious length. The J121 was designed for short offshore races such as Fastnet or Middle Sea Race and so on. And the calculation proved to be true: the J121 has recently collected an impressive luggage of medals.
