Design and Construction
The hull is a sleek high-tech composite structure with solid fiberglass below and a solid fiberglass deck, carrying 5,000 pounds of lead ballast in a bulb keel that keeps the center of gravity low anchor. At 12,600 pounds displacement on the deep-draft version and 11 feet 4 inches of beam, the 40-foot 8-inch hull draws 6 feet 10 inches and rides on a carbon-fiber rudder anchor. The set-back headstay and pulpit give the bow a modestly aggressive look, while the decks themselves stay uncluttered for easy movement forward anchor. The low center of gravity from the bulb and the spade rudder define her handling character as a performance coastal boat.
Rig and Handling
Up top, a stiff, lightweight Hall Spars carbon rig carries more than 750 square feet of working sail on the 100 percent foretriangle, and the deep 754-square-foot plan drives a boat that tracked easily upwind in period testing anchor. Sheets lead to winches near the helm, and the split mainsheet runs under the deck to winches just forward of the wheel, with the traveler on the cockpit sole where it is easily managed and the mainsail controls conveniently at hand anchor. An optional Hoyt self-tacking jib boom makes shorthanded sailing a snap, and steering runs through a 54-inch carbon wheel anchor. The cockpit itself is extra-large, with 14-inch backrests and seats long enough for sleeping under the stars, protected by a dodger for all-weather use anchor.
Accommodations
Below, the J/124 is a weekender's interior rather than a liveaboard's: three sleeping bunks distributed through modest forward and aft cabins, a comfortable saloon with long straight settees, a small galley, and a head anchor. Cruising World's survey adds the detail that the head is aft to starboard, the galley is simple, and there is a stand-up chart table for passage planning at the dock anchor. Six feet of headroom runs through the accommodation, and storage is generous for the type thanks to aft lazarettes and a huge starboard cockpit locker that can also be opened from inside the head anchor.
Power and Systems
A 40-horsepower Yanmar diesel moves the boat when the wind fails, backed by 25 gallons of fuel and 35 gallons of water anchor. The modest tankage reinforces the design brief: this is a boat for overnights and long weekends, not provisioning for a crossing.
The Verdict
The J/124 succeeds as a refined coastal weekender that trades offshore ambition for sparkling short-handed performance and a clean, open deck. Her carbon rig, low-center-of-gravity bulb, and helm-centered controls make her a joy to sail with two aboard, and the cockpit is among the most usable of her size. The interior is honest about its limits — compact but well laid out, with clever locker access that enlarges perceived storage.
Pros
- Carbon rig and bulb keel deliver easy upwind tracking and low-effort shorthanded sailing
- Helm-adjacent sheet and mainsheet winches with under-deck leads keep the cockpit clear
- Extra-large cockpit with sleeping-length seats and dodger extends living space outdoors
- Stand-up chart table and head-accessible starboard locker are thoughtful weekender details
Cons
- 25-gallon fuel and 35-gallon water capacity restrict range and time aboard
- Modest cabins and a small galley suit overnights, not extended cruising
- Only 35 built, so finding a specific example takes patience
