Design and Construction
The Atlantic 49 has a solid-fiberglass monohull, a fin keel, and a skeg-hung rudder—a configuration suited to a maneuverable coastal platform. She measures 49 feet overall, with a 47.13-foot waterline and a 15.02-foot beam. Displacement is 26,455 pounds, including 8,377 pounds of lead ballast, for a ballast-to-displacement ratio of 31.67 percent.
That moderate ballast figure, combined 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. However, her capsize screening figure of 2.02 puts her at the threshold for blue-water suitability rather than clearly within it.
Rig and Handling
The masthead sloop rig has an 18-meter foretriangle and a 15.5-meter mainsail luff. A sail-area-to-displacement ratio of 17.0 puts her in the range for reasonably good performance under sail.
Period assessments describe better acceleration and more responsive handling than heavier boats offer. Her decent power-to-weight balance makes it relatively easy to push her toward a 9.2-knot hull speed with a moderate working sail plan.
Auxiliary power comes from a single 80-horsepower Ford Lehman diesel, the kind of engine expected on a boat this size. One review, however, flatly calls her underpowered for the hull. That caveat is worth weighing against her light-displacement handling, which otherwise makes her feel quick.
Performance and Seakeeping
A comfort ratio of 23.24 indicates the motion of a coastal cruiser with moderate stability, suited to family outings and sheltered-water passages. The Atlantic 49 is reasonably stable and stiff, but she won’t ride through rougher seas with the composure of a deeper-ballasted offshore design. Her low righting capability if capsized also places a firm limit on where she belongs.
Reviewers agree that she can attempt shorter or less demanding ocean trips, but she remains best regarded as a coastal cruiser first and a borderline blue-water boat second.
Accommodations and Tankage
What the Atlantic 49 lacks in offshore margin, she makes up for in cruising range at anchor. Her 211-gallon water capacity provides an excellent supply, while the 74-gallon fuel capacity is average for a boat of this size.
The water capacity is the standout figure for a couple or family cruising the Mediterranean, allowing long intervals between fills even with a full complement of guests. Her beamy 15-foot hull provides the liveaboard volume you’d expect.
Verdict
The Atlantic 49 is a well-balanced coastal cruiser with good light-air performance and a roomy platform for warm-water cruising, backed by unusually generous water capacity. She accelerates quickly and is easy to handle for her length. However, her capsize and righting figures 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 toward hull speed
- Excellent 211-gallon water capacity for extended coastal and charter-style cruising
- Beamy 15-foot hull, solid-fiberglass construction, and a skeg-hung rudder
Cons
- Low righting capability if capsized, with a capsize screening figure at the blue-water threshold
- Flatly called underpowered for her size despite the 80 HP auxiliary
- A comfort ratio that suggests less settled motion than heavier boats provide in rough seas
