Design and Construction
The Atlantic 49 is built in solid fiberglass with a monohull fin keel and a skeg-hung rudder, a configuration that matches her role as a maneuverable coastal platform. At 49 feet overall with a 47.13-foot waterline and a 15.02-foot beam, she carries 26,455 pounds of displacement and 8,377 pounds of lead ballast for a ballast-to-displacement ratio of 31.67 percent. That moderate ballast figure, paired with a displacement-to-length ratio near 113 on the spec record, places her among lighter cruisers. J&J's hull form gives her reasonable stiffness and stability, but the capsize screening figure of 2.02 leaves her right at the threshold for blue water suitability rather than clearly inside it.
Rig and Handling
Her masthead sloop rig spans an 18-meter foretriangle and a 15.5-meter mainsail luff, and the sail-area-to-displacement ratio of 17.0 puts her in the band for reasonably good performance under sail. Period assessments describe better acceleration and more responsive handling than heavier boats show, with a decent power-to-weight balance that makes her relatively easy to push to her 9.2-knot hull speed on a moderate working sail plan. The single 80-horsepower Ford Lehman diesel is the kind of auxiliary you expect on a boat this size, though one review flatly calls her under powered for the hull — a caveat worth weighing against the light-displacement handling that otherwise makes her feel quick.
Performance Envelope
The comfort ratio of 23.24 marks her motion as typical of a coastal cruiser with moderate stability, suited to family outings and sheltered-water passages. She is reasonably stable and stiff, but in rougher seas she will not ride with the composure of a deeper-ballasted offshore design, and the low righting capability if capsized is a hard limit on where she belongs. Reviewers agree she can attempt shorter or less demanding ocean trips yet remains better cast as a coastal cruiser first, a borderline blue water boat second.
Accommodations and Tankage
What the Atlantic 49 lacks in offshore margin she recovers in cruising range at anchor. Her 211-gallon water capacity is an excellent supply range, and the 74-gallon fuel figure is average for a boat of this size. That water capacity is the standout number for a couple or family on a Mediterranean swing, giving long intervals between fills even with a full complement of guests. The beamy 15-foot hull supports the liveaboard volume you would expect.
The Verdict
The Atlantic 49 is a well-balanced coastal cruiser with good light-air performance and a roomy, water-rich platform for warm-water cruising. She is quick to accelerate and easy to handle for her length, but her capsize and righting numbers keep her out of the serious offshore class despite a borderline rating for shorter passages.
Pros
- Light, responsive handling with a sail-area-to-displacement ratio that makes her easy to drive to hull speed
- Excellent 211-gallon water capacity for extended coastal and charter-style cruising
- Beamy 15-foot hull with solid fiberglass construction and a skeg-hung rudder
Cons
- Low righting capability if capsized and a capsize screening figure at the blue water threshold
- Flatly called under powered for her size despite the 80 HP auxiliary
- Comfort ratio marks her as less settled than heavier boats in rough seas
