The design is aimed at coastal and inland European waters rather than ocean racing. Its keel options allow owners to choose between deeper-draft performance and access to shallow water.
Design and Construction
The Sun Rise 34 measures just under 35 feet overall, with a 29.5-foot waterline, an 11.45-foot beam, and a displacement of roughly 10,360 pounds. Its length-to-beam ratio is 3.02, giving it a broad section that supports interior volume. The wetted surface of the bottom is about 409 square feet.
Both the hull and deck are solid fiberglass. Iron ballast weighs 3,460 pounds, for a ballast-displacement ratio of 33.4 percent.
Jeanneau offered two keel arrangements, and the choice defines much of the boat’s character. The stub-centerboard version combines a fixed stub keel with a retractable centerboard. Depending on load, it draws about 3.61 to 3.91 feet, allowing the boat to sail in coastal and inland waters, and enter even shallow marinas.
The fin keel draws about 5.91 to 6.21 feet, depending on load. That restricts the boat to major marinas but provides a more conventional upwind profile.
The design has a comfort ratio of 20.07 and a capsize screening value of 2.10. The latter falls outside the accepted envelope for ocean racing—a boundary worth stating plainly rather than treating as a criticism.
Rig and Sail Plan
The Sun Rise 34 has a masthead rig with a reference sail area of 516 square feet. Its sail-area-to-displacement ratio is 17.4 with the ISO 8666 reference sail, rising to 20.9 with a 135 percent genoa. That spread shows how strongly the overlapping headsail drives the boat.
The mast stands 48.58 feet above the waterline, and the rig’s modest aspect suits the boat’s moderate displacement.
The specified halyard and sheet lengths are generous for a boat of this size:
- Mainsail, jib, and spinnaker halyards: 99.5 feet
- Genoa and jib sheets: 34.6 feet
- Mainsheet: 86.5 feet
These dimensions are useful when replacing running rigging. The specified stations take 12 mm halyards and 14 mm sheets.
Performance Profile
A displacement-length ratio of 180.17 and an immersion rate of about 1,380 pounds per inch describe a boat that carries its weight in a stable, predictable manner rather than behaving like a featherweight planing hull.
Hull speed is near 7.3 knots. Combined with the genoa-driven sail plan, that makes the Sun Rise 34 a competent coastal cruiser. Its capsize screening value of 2.10 means it wouldn’t be accepted for ocean racing, which gives buyers a useful boundary when comparing it with deeper-bluewater candidates. The design data state those limits honestly rather than obscuring them with marketing.
Accommodations and Machinery
The boat’s 34.58-foot length and broad beam provide a three-cabin owner layout that was uncommon for the period. That accommodation plan was available with either the shoal-draft stub-centerboard or fin keel, depending on the build.
Water capacity is 30 gallons, while fuel capacity is 18 gallons. Those tank sizes suit weekending and short coastal passages better than extended independent voyaging.
A 27-horsepower Yanmar 2GM20F diesel may be fitted as the inboard. It is a small but adequate auxiliary for a boat of this displacement.
Known Issues
On the stub-centerboard variant, the pivot and wear surfaces are conventional wear points. Any used example should be checked for free movement and the condition of its seals. However, the available material provides no quantified failure rates or measurements.
The Verdict
The Sun Rise 34 is a thoughtfully specified mid-1980s cruiser whose keel options broaden its appeal across coastal and inland European waters. By the numbers, it is well mannered, with a genoa-driven rig and a beamy hull that provides useful interior volume without pretending to ocean-racing credentials.
For sailors looking for a manageable, documented, and comparatively plentiful 34-footer, it remains a sensible choice.
Pros
- Shoal-draft stub-centerboard variant provides access to shallow marinas and inland waterways
- Beamy three-cabin layout was rare for the era
- Clear, published rig dimensions simplify re-rigging
Cons
- Capsize screening value excludes it from ocean racing
- Fin-keel draft restricts marina access
- Fuel and water capacities are modest for longer passages
