The 61 m (200 ft) superyacht Just J's was launched by Hakvoort Shipyards at its yard in Monnickendam.

It was the largest yacht built by Hakvoort[3] until the 2019 launch of Scout.

The hull is built out of steel while the superstructure is made out of aluminium with teak-laid decks.

Featuring on the sundeck is a 3x2-metre pool forward with a contraflow system.

Among other amenities on board are a gym and a cinema room on the bridge deck, as well as a tender and four jetskis that are launched from large gullwing doors on either side of the yacht.
