CS 34 Information, Review, Specs

Sailing Performance & Handling

The CS 34 is widely regarded as a "sailor’s boat," benefiting from Tony Castro’s background in racing yacht design. With a Sail Area/Displacement ratio typically hovering around 18.5, the boat is remarkably responsive in light air, a trait that sets it apart from heavier cruisers of the same era. The hull features a relatively flat run aft and a fine entry, which allows it to track well upwind while remaining stable when pushed off the wind.

Handling characteristics are defined by a balanced spade rudder and the choice of two keel configurations: a deep fin for maximum lift and a wing keel for those navigating shallower coastal waters. Owners frequently report that the boat remains manageable even when overpowered, though reefing early is rewarded with a more upright, comfortable ride. The placement of the primary winches and the mainsheet traveler—typically located on the coachroof—keeps the cockpit clear for passengers while allowing the helmsman to maintain control over the sail trim.

Interior Comfort & Variations

The interior of the CS 34 reflects the high standards of the Brampton, Ontario, factory, utilizing extensive teak joinery and a layout that maximizes the 11' 3" beam. The most common configuration features a traditional V-berth forward, a central salon with a folding leaf table, and a standout aft cabin. This aft cabin was a significant selling point at the time of its release, offering a large athwartships double berth that provides considerably more privacy and headroom than the "crawl-in" berths found on smaller models like the CS 30.

The galley is typically L-shaped, positioned to starboard, and equipped with a deep icebox and a two-burner propane stove. One of the subtle design successes of the CS 34 is the ventilation; with multiple opening Lewmar ports and overhead hatches, the cabin avoids the "stuffy" feel common in older fiberglass boats. While there were no major structural "sibling" variants (such as a deck salon version), the model did see minor interior updates toward the end of its production run in the early 1990s, including variations in upholstery and cabin sole materials.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a CS 34 survey with a focus on a few specific areas common to the build style and the era of construction.

• Structural Grid Bonding: Like many CS models, the 34 uses a fiberglass grid system for structural rigidity. High-load areas, particularly around the mast step and the forward end of the grid, should be inspected for any signs of "crazing" or separation from the hull, which can occur if the boat has been subjected to a hard grounding.
• Portlight Seals: The original Lewmar portlights are known to develop leaks over time as the gaskets compress or the plastic frames craze. Water intrusion here can damage the interior teak veneers if left unchecked.
• Rudder Moisture: The spade rudder is a foam-filled fiberglass component. It is common for these to trap moisture over decades. A percussion test and moisture meter reading are essential to ensure the internal stainless steel skeleton is not suffering from crevice corrosion.
• Keel-to-Hull Joint: While the "CS Smile" (a hairline crack at the leading edge of the keel/hull joint) is common and often cosmetic, it should be monitored to ensure the keel bolts remain torqued to manufacturer specifications, especially on wing-keel versions which exert different leverage forces on the hull.

Community & Resources

The primary hub for technical data and historical documentation is the CS Owners Association, which maintains an extensive archive of original brochures, manual scans, and a registry of hull numbers. This community is particularly active in the Northeast United States and Canada, providing a wealth of peer-to-peer knowledge regarding modern upgrades for the CS 34’s Yanmar diesel engines and standing rigging.

The Verdict

The CS 34 is a premier example of "Classic Plastic" that bridges the gap between a performance racer and a comfortable coastal cruiser. It is an ideal choice for a small family or a couple looking for a boat that is fast enough to be competitive in Wednesday night club racing while being robust enough for extended cruising.

Pros:

• Exceptional build quality with high-end teak interior finishes.
• Strong performance in light to moderate winds thanks to a Tony Castro hull design.
• The aft cabin is remarkably spacious for a 34-foot vessel.

Cons:

• Spade rudder and light displacement require more attention at the helm than a full-keel cruiser.
• Replacement parts for original Lewmar hardware and specific CS castings can be difficult to source.
• The wing-keel version, while practical for shallow water, sacrifices some pointing ability compared to the deep-fin model.
