Yamaha 35 CS Information, Review, Specs

Sailing Performance & Handling

On the water, the Yamaha 35 CS is defined by a masthead sloop rig and a well-balanced underwater profile featuring a deep fin keel and a spade rudder. This configuration provides the boat with a relatively stiff and predictable motion in a seaway. With a displacement-to-length ratio that leans toward the "moderate-heavy" cruising category, the 35 CS does not bob like lighter modern production boats; instead, it punches through chop with significant momentum.

Handling is reported by owners to be exceptionally honest, with a high degree of "feel" through the wheel. Because Yamaha applied 3D CAD and CNC technology—rare for the late 70s—the hull symmetry is remarkable, resulting in a boat that tracks straight even when pressed hard. While its Sail Area to Displacement ratio is not that of a pure racer, the 35 CS performs admirably in light air if the bottom is kept clean, though it truly shines in 15 to 20 knots of breeze. The spade rudder offers high maneuverability in tight marinas, a necessity given the boat's significant lateral windage. According to historical design notes from the Yamaha Motor Global History archives, the company’s focus was on "enjoying life" through reliable, stress-free operation, which translated into a sail plan that is easily managed by a couple.

Interior Comfort & Variations

The "CS" designation—often interpreted as Center Saloon or Center Suite—is the defining characteristic of this model’s interior. Yamaha’s design team deviated from the cramped "tunnel" feel of standard 35-footers by utilizing the wide beam to create an expansive midships living area. The joinery is a standout feature, utilizing high-quality teak and marine-grade resins that have aged significantly better than many of its 1980s counterparts.

The layout typically features a large V-berth forward, followed by a heads compartment that spans the width of the boat, and a main saloon with a U-shaped settee. The "Suite" aspect refers to the careful integration of the galley and navigation station, which feel like distinct rooms rather than afterthoughts. Headroom is generous, often exceeding 6'2", making it a viable long-term coastal cruiser for taller sailors.

The 35 CS had several siblings within the Yamaha lineup. The Yamaha 33 was its smaller, more performance-oriented cousin, while the Yamaha 37 offered a larger platform with similar "Stripe" design cues. There was also a standard Yamaha 35 (non-CS) which featured a more traditional aft-cockpit layout and a different interior arrangement, appealing to those who preferred a larger cockpit over the expanded "Center Suite" cabin volume.

Known Issues & Buyer’s Checklist

Prospective buyers of a Yamaha 35 CS should focus on three primary areas during survey:

1. Hardware Sourcing: Because many of the deck fittings and portlights were manufactured in-house by Yamaha or sourced from Japanese vendors now defunct in the sailboat sector, replacing exact hardware can be difficult. Look for signs of "creative" repairs to winches or stanchion bases that might indicate a lack of genuine parts.
2. Engine Longevity: Many original 35 CS models were equipped with Yamaha-branded diesel engines or early Yanmar units. While the hulls are nearly indestructible, an original engine will likely be at the end of its service life. Buyers should check for exhaust elbow corrosion and parts availability for these specific older Japanese marine blocks.
3. Deck Core Integrity: While Yamaha’s FRP work was superior, they used balsa-coring in the decks for weight savings. Check specifically around the chainplates and the mast step for "soft spots" or delamination, as the complex interior moldings of the CS version can make accessing the underside of the deck for repairs quite labor-intensive.
4. Rudder Bearings: The spade rudder design places significant load on the upper and lower bearings. Any "thumping" or play in the steering should be addressed, as these bearings are often custom-machined and require professional replacement.

Community & Resources

Owners of Yamaha sailboats are a dedicated but niche group. The most prominent resource for technical data and hull-specific advice is the Yamaha Sailboat Owners Association, which maintains an informal registry and archive of original Japanese brochures and wiring diagrams. While the company has moved away from sailboat production to focus on outboards and jet boats, the legacy is maintained through dedicated enthusiast groups who prize the "overbuilt" nature of these vintage cruisers.

The Verdict

The Yamaha 35 CS is an "orphan" classic that offers build quality far exceeding its current market price. It is an ideal vessel for the sailor who values industrial-grade construction and a unique interior layout over brand-name recognition.

• Pros: Exceptional FRP build quality; stiff and stable offshore performance; unique, spacious "Center Suite" interior; high-quality vintage teak joinery.
• Cons: Hard-to-source proprietary hardware; significant windage in the "CS" configuration; original engines are often aged; limited brand support for sailboats in the US/EU markets.
