Design and Construction
Brewer paired a solid steel hull with a steel deck, a construction choice that defines the boat’s character more than any single dimension. The 11-foot-3-inch beam gives a length-to-beam ratio of 3.09, a modest figure that points to interior volume rather than racer-like narrowness.
The Aragosa 35 displaces 15,250 pounds on a 28-foot-6-inch waterline. Her displacement-length ratio of 294 places her firmly among what one design-ratio study calls “heavy cruisers.” She carries 5,400 pounds of lead ballast, giving a ballast ratio of 35 percent.
That ballast is fixed in a fin keel drawing between 5.31 and 5.61 feet, depending on load. This is shallow enough that the boat can enter most marinas without drama. A lightly loaded boat will float slightly higher, while a fully provisioned one will sit slightly deeper, but the range is narrow enough that marina access is rarely a concern.
The underwater body has about 355 square feet of wetted surface. An immersion rate of roughly 1,118 pounds per inch means she settles under added load without becoming overly sensitive to it. A capsize screening value of 1.81 and a Motion Comfort Ratio of 30.7 both point to a vessel conceived for steadiness offshore rather than sparkle around the buoys.
Rig and Handling
The masthead sloop rig carries 631 square feet of sail. That produces a sail-area-to-displacement ratio of 16.41—a moderate figure that, combined with the boat’s heavy displacement, marks her as a patient rather than urgent sailer. It also suggests that she’ll be slow to accelerate in light air.
With a 28.5-foot waterline, her theoretical hull speed as a displacement boat is 7.2 knots. The fin keel and skeg-hung rudder provide predictable steering, while her displacement, ballast, and design ratios shape a boat intended to carry its load with composure.
Accommodations and Systems
The principal dimensions—15,250 pounds of displacement and an 11.25-foot beam—suggest roomy interior volume. The steel hull and deck enclose the accommodation spaces and provide durability and insulation, though steel construction also demands vigilant corrosion inspection.
Fresh-water capacity is 378 liters, or 99 US gallons. That’s a generous allowance for a 35-foot cruiser and a clear sign that the design was intended for self-sufficient stretches away from port. The tankage and heavy construction were specified together as a system for extended coastal or offshore use.
Verdict
The Aragosa 35 is a Brewer-designed steel cruiser for sailing where comfort and ballast matter more than pace. Her figures—a 35 percent ballast ratio, 30.7 Motion Comfort Ratio, and 1.81 capsize screening value—describe a boat intended for offshore steadiness and conceived to stand up to weather and carry her load without fuss.
Steel construction and deep tankage suit a buyer who values substance over finish. Her moderate draft also keeps her practical in ordinary harbours and gives access to most marinas.
Pros
- Heavy-cruiser displacement and a 35 percent ballast ratio support offshore steadiness
- Steel hull and deck provide durability and insulation
- 99-gallon fresh-water capacity supports extended cruising
- Moderate draft of 5.3–5.6 feet keeps most marinas accessible
Cons
- A sail-area-to-displacement ratio of 16.41 points to slow acceleration in light air
- Steel construction requires vigilant corrosion inspection
