Olson 911 S Information, Review, Specs

Sailing Performance & Handling

The performance profile of the Olson 911 S is defined by its high Sail Area to Displacement (SA/Disp) ratio, which positions it as a high-powered vessel capable of exceptional light-air performance. Unlike the earlier Olson 30, which could be temperamental on the wind, the 911 S features a deeper, more efficient fin keel and a balanced spade rudder that provide a more positive "groove" when beating to weather. According to design notes from George Olson, the hull was shaped to minimize wetted surface while maintaining enough waterline beam to provide a stable platform for the powerful fractional rig.

In heavy air, the 911 S remains a true ULDB at heart. While it tracks better than its smaller siblings, it still demands an active crew to manage sail trim and weight distribution. The boat is known for its ability to plane in moderate breezes, particularly under a large masthead symmetric or asymmetric spinnaker. Owners often describe the handling as "dinghy-like," offering immediate feedback through the tiller. This responsiveness is a hallmark of the Pacific Boat Works era, where weight was concentrated low and amidships to reduce the polar moment of inertia, resulting in a boat that handles waves with a nimble, athletic motion rather than the hobby-horsing common in heavier cruiser-racers of the same period.

Interior Comfort & Variations

Inside, the Olson 911 S offers a functional and surprisingly spacious layout for a performance-oriented 30-footer. The interior was a significant selling point compared to the Olson 29 or 30, featuring approximately six feet of headroom and a traditional arrangement that includes a V-berth forward, a central salon with two settee berths, and a compact galley. The use of teak trim and molded fiberglass liners gives the cabin a clean, finished appearance that was a step up from the "industrial" feel of earlier Santa Cruz builds.

A notable variation in the model's history occurred when the design was acquired by Ericson Yachts. The Ericson 911 (often marketed without the "S") utilized the same George Olson hull but featured a slightly different deck mold and interior finish, emphasizing a "cruiser-first" mentality with more substantial wood cabinetry and upgraded hardware. Another sibling in the Olson lineage is the Olson 34, which utilized similar design principles on a larger scale to provide a more offshore-capable platform. For those seeking a more stripped-down racing experience, the Olson 29 serves as the 911 S’s smaller, lighter sibling, built on a similar philosophy but without the cruising amenities of the 911 S.

Known Issues & Buyer’s Checklist

Prospective buyers of an Olson 911 S should approach the vessel with an eye for the typical stresses found in high-performance fiberglass boats from the 1980s.

• Deck Core Integrity: Like many boats from Pacific Boat Works, the 911 S utilizes a balsa-cored deck. Areas around the chainplates, stanchion bases, and the mast step are prone to moisture ingress if the sealant has failed. Soft spots in these areas are a common "gotcha" that can lead to expensive repairs.
• The "Olson Smile": A common structural concern is the joint where the lead keel meets the fiberglass hull stub. While often just a cosmetic crack in the fairing compound, a significant gap can indicate that the keel bolts require re-torquing or that the hull stub has suffered compression damage from a previous grounding.
• Rudder Bearings and Post: The spade rudder on the 911 S is a high-aspect foil that takes significant loads. Buyers should check for play in the rudder bearings and inspect the rudder post for any signs of electrolysis or delamination of the blade itself.
• Chainplate Inspection: The 911 S uses a powerful rig that puts substantial tension on the shroud terminals. It is critical to inspect the stainless steel chainplates where they pass through the deck and attach to the bulkheads for signs of crevice corrosion or "weeping" rust.

Community & Resources

The Olson 911 S benefits from a robust and highly technical community of owners, largely centered around the Santa Cruz sailing scene. The most prominent resource for technical support and class rules is the Olson 30 Class Association, which, while focused on the 30, often serves as a hub for all George Olson designs. Additionally, because Ericson Yachts eventually took over the production of the 911, the Ericson Yachts Owners community provides extensive technical wikis and historical documentation that cover the hull and structural components shared between the Pacific Boat Works and Ericson versions.

The Verdict

The Olson 911 S is an iconic piece of West Coast sailing history that remains one of the most versatile 30-footers on the used market. It is an ideal choice for the sailor who refuses to choose between a competitive racing platform and a boat capable of weekend family cruising.

Pros:

• Exceptional light-air performance and planing potential.
• Spacious interior with standing headroom, rare for a ULDB.
• Highly responsive handling that rewards skilled sail trim.
• Strong resale value due to the enduring legacy of George Olson's designs.

Cons:

• Lightweight construction requires diligent maintenance of the balsa core.
• Can be physically demanding to sail to its full potential in heavy weather.
• The fractional rig requires more sophisticated tuning than a standard masthead rig.
