Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

TrailerableBeam 2.47 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,043 kg of hull, so roughly 1,650 kg on a trailer: check that against your own towing rating.Shoal draughtDraws 1.16 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.

The J J/7 is a 7-meter fractional sloop daysailer designed by Alan Johnstone and built by J Boats since 2024. It features a fin keel with a bulb and a transom-hung rudder, displacing 1043 kg with a draft of 1.16 meters.2:39 Positioned as a more affordable and family-friendly alternative to the J Boats J/70, the J/7 is built in China to reduce costs.0:02 Its hull is wider and heavier than the J/70, and its higher ballast-to-displacement ratio contributes to its stiffness.1:53 The cockpit accommodates seven people, and while it has below-deck space, it is spartan, suiting day sailing over cruising.2:18 The standard sail inventory includes a mainsail and jib, with a fixed bowsprit and an optional gennaker.2:03 SEILmagasinet reports a complete price of approximately 700,000 Norwegian kroner, including sails and a sun awning.2:45
