Design and Construction
Soverel Marine built the 28 as a solid-fiberglass monohull, including both hull and deck. She has a centerboard keel and a spade rudder—the latter a modern choice for the early 1960s that helps with low-speed turning.
Estimated lead ballast is 2,778 pounds against a displacement of 7,000 pounds, for a ballast-displacement ratio of roughly 39.7 percent. Her displacement-length ratio of about 241 puts her firmly in the heavy, seakindly camp rather than among featherweight racers. A capsize screening value of 1.74 and a comfort ratio of 25.69 reinforce the picture of a small boat with offshore-leaning stability numbers.
With the centerboard raised, draft is 2.67 feet; lowered, it increases to 4.5 feet. That range allows the boat to dry out or gunkhole while providing more ability to stand up to sail with the plate lowered.
Rig and Sail Plan
The standard Soverel 28 carries a masthead sloop rig. Its dimensions are an I of 33.6 feet, J of 11.8 feet, P of 30.6 feet, and E of 12.2 feet. The mainsail works out to about 187 square feet, with a racing cut adding ten percent for roughly 206 square feet, according to this sail area calculation table.
A 155 percent genoa measures about 327 square feet, while a 135 percent genoa is about 285 square feet and a 100 percent jib is near 198 square feet. A 94 percent jib fills the foretriangle. The spinnaker envelope runs from 503 to 611 square feet, with a square spinnaker around 719 square feet and an asymmetrical around 599 square feet.
Sources don’t present a single fixed specification across all sub-variants. A separate database entry lists a SOVEREL 28 with an I of 34.3 feet, J of 11.2 feet, P of 30.9 feet, and E of 13.2 feet. That version has a 23.3-foot waterline, 3-foot draft, and 7,000-pound displacement. The MORC variant is listed with a 24.16-foot waterline, 6.5-foot draft, and 6,500-pound displacement.
Accommodations
At 28.5 feet long with an 8.33-foot beam, the Soverel 28 sits at the roomy end of the MORC-class envelope. As on any centerboard boat of this type, however, the centerboard trunk necessarily takes up floor space amidships that a fixed-keel design would leave open.
Available information on accommodations and systems is sparse. In practice, each boat’s individual history and modifications are likely to matter more than a general class description.
Machinery, Refit, and Ownership
Builder records note a Palmer gasoline engine, a period inline unit. After six decades, any surviving boat will almost certainly have been repowered or, at minimum, rewired over that period.
With only 90 boats built during a nine-year production run, the Soverel 28 remains a small class. Class support and spare-parts availability are correspondingly thin, so a buyer will need to rely more heavily on the condition and documentation of the individual boat.
The centerboard trunk, its pivot, the spade-rudder stock and bearing, and the chainplate landings are the usual long-service wear points on a 1960s solid-fiberglass centerboarder. Although the spade rudder construction helps with low-speed turning, it remains a wear item after decades of service.
The centerboard trunk and spade rudder are the components most likely to have undergone repair or modification. A buyer should treat undocumented structural work as a negotiation point rather than automatically regarding it as a defect.
The Verdict
The Soverel 28 is a quietly capable small centerboard sloop. Her stability numbers and flexible draft stand out for a boat of this length, while her solid-fiberglass construction, masthead rig, and broad range of downwind sail options add practical appeal.
The tradeoff is uncertainty. Sources disagree on dimensions across the sub-variants, class support is limited, and detailed information on accommodations and systems is scarce. A purchaser will need to lean more heavily on a surveyor and the history of the individual boat than on a well-established class profile.
Pros
- Centerboard provides 2.67-foot board-up draft for trailering and shoal access, with 4.5-foot board-down draft for sailing.
- Ballast ratio near 40 percent and comfort ratio of 25.69 suggest a stiff, settled small boat.
- Solid-fiberglass hull and deck.
- Spade rudder and masthead sloop rig, with a well-developed range of downwind sails.
Cons
- Only 90 boats were built; class support and spare parts are thin.
- Sources disagree on dimensions across the sub-variants, complicating expectations.
- Accommodation and systems information is sparse.
- Every surviving example is a personal-history research project.
