Design and Construction
The J/124 has a sleek, high-tech composite hull, with solid fiberglass below and a solid fiberglass deck. A bulb keel carries 5,000 pounds of lead ballast and keeps the center of gravity low https://sailmagazine.com/boats/j124/.
The deep-draft version displaces 12,600 pounds. The hull measures 40 feet 8 inches overall, with a beam of 11 feet 4 inches and a draft of 6 feet 10 inches. A carbon-fiber rudder provides steering. Together with the low center of gravity from the bulb keel, the spade rudder helps define the boat’s handling as a performance-oriented coastal design.
The set-back headstay and pulpit give the bow a modestly aggressive look, while the uncluttered decks make it easy to move forward.
Rig and Handling
A stiff, lightweight Hall Spars carbon rig carries more than 750 square feet of working sail on the 100 percent foretriangle. In period testing, the 754-square-foot sail plan drove a boat that tracked easily upwind https://www.cruisingworld.com/sailboats/j-124/.
The sheets lead to winches near the helm. The split mainsheet runs below deck to winches just forward of the wheel, while the traveler sits on the cockpit sole, where it is easy to manage. This arrangement keeps the mainsail controls close at hand without cluttering the cockpit.
An optional Hoyt self-tacking jib boom makes shorthanded sailing straightforward, and steering is through a 54-inch carbon wheel. The extra-large cockpit has 14-inch backrests and seats long enough for sleeping under the stars. A dodger provides protection for all-weather use.
Accommodations
Below, the J/124 has the interior of a weekender rather than a liveaboard. Three sleeping bunks are distributed between modest forward and aft cabins. The accommodation also includes a comfortable saloon with long, straight settees, a small galley, and a head https://sailmagazine.com/boats/j124/.
Cruising World’s survey places the head aft to starboard and describes the galley as simple. There is also a stand-up chart table for passage planning at the dock. Headroom is 6 feet throughout the accommodation.
Storage is generous for this type of boat, with aft lazarettes and a huge starboard cockpit locker. That locker can also be opened from inside the head, providing useful access below.
Power and Systems
A 40-horsepower Yanmar diesel provides auxiliary power, supported by 25 gallons of fuel and 35 gallons of water https://www.cruisingworld.com/sailboats/j-124/. The modest tankage reinforces the design brief: this is a boat for overnights and long weekends, not for provisioning for a crossing.
Verdict
The J/124 succeeds as a refined coastal weekender, trading offshore ambition for lively shorthanded performance and a clean, open deck. Its carbon rig, low-center-of-gravity bulb keel, and helm-centered controls make it a pleasure to sail with two aboard. The cockpit is among the most usable for a boat of this size.
The interior is equally honest about its limits. It is compact but well laid out, and clever locker access makes the available storage feel more generous.
Pros
- Carbon rig and bulb keel provide easy upwind tracking and low-effort shorthanded sailing
- Sheet and mainsheet winches near the helm, with below-deck leads, help keep the cockpit clear
- Extra-large cockpit, sleeping-length seats, and a dodger extend the living space outdoors
- Stand-up chart table and head-accessible starboard locker are thoughtful weekender details
Cons
- Fuel capacity of 25 gallons and water capacity of 35 gallons restrict range and time aboard
- Modest cabins and a small galley suit overnights rather than extended cruising
- Only 35 were built, so finding a specific example takes patience
