Olympic Adventure 38 Information, Review, Specs

Sailing Performance & Handling

The Olympic Adventure 38 is defined by its heavy-displacement hull and a modified full keel—often featuring the "Brewer Bite," a cut-away section forward of the skeg-hung rudder intended to reduce wetted surface area and improve maneuverability. With a high Displacement-to-Length (D/L) ratio likely exceeding 320, the boat is remarkably stable and excels in heavy air, where its mass allows it to power through chop that would stall lighter vessels.

Owners and technical reviewers note that the boat’s motion is exceptionally "kind," with a high comfort ratio that minimizes the sharp pitching associated with modern flat-bottomed designs. However, the trade-off is evident in light winds; the Adventure 38 requires a significant breeze to overcome its inertia and wetted surface. The Sail Area-to-Displacement (SA/D) ratio is modest, making the vessel feel under-canvased in less than 10 knots of wind. Most models were rigged as ketches, providing a versatile sail plan that allows for "mule" configurations (jib and mizzen) during squalls, which maintains balance and reduces heel.

Interior Comfort & Variations

The Adventure 38 was primarily produced in a center-cockpit configuration, a design choice that maximizes privacy and provides a distinct aft cabin—a rare luxury for a 38-foot yacht of this vintage. The interior is characterized by extensive use of solid teak and high-quality joinery, reflecting the labor-intensive construction methods of the Lavrio-based shipyard.

The layout typically features a V-berth forward, followed by a full-beam salon with a drop-leaf table. The galley is situated in the passageway leading aft, which allows for excellent bracing while cooking at sea. The aft cabin is the centerpiece, often containing a double berth and private access to the head, though some variants were configured with split singles. Because of its 12-foot beam and high freeboard, the interior volume feels significantly larger than comparable 38-footers of the era. A rare aft-cockpit version was also produced in limited numbers, which prioritized a larger salon at the expense of the separate master suite.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Olympic Adventure 38 with an awareness of its age and the specific construction techniques of the 1970s.

• Deck Delamination: Like many boats of this era, the Adventure 38 often utilized a balsa or plywood core for the decks. If the hardware was not re-bedded periodically, water ingress can lead to significant soft spots, particularly around the chainplates and the mast step.
• Osmotic Blistering: Early Greek fiberglass builds are occasionally prone to osmosis. While the hulls are thick and structurally "overbuilt," a haul-out inspection is mandatory to check for hull blistering or moisture retention in the laminate.
• Teak Deck Integrity: Many Adventure 38s were delivered with thick teak decks screwed directly into the fiberglass. Over decades, these screws can become leak points into the core. If the teak is original, it is likely at the end of its service life.
• Engine Access: While the center-cockpit layout provides a dedicated engine room under the cockpit sole, access can be tight for major repairs. Buyers should inspect the state of the original Perkins or Volvo Penta engines, as many are now due for replacement.
• Chainplates: The stainless steel chainplates are glassed into the hull or bolted to heavy bulkheads; they should be inspected for crevice corrosion, especially where they pass through the deck.

Community & Resources

Support for the Olympic Adventure 38 is largely found within broader networks dedicated to the designer's work. Owners often congregate in the Ted Brewer Design fan groups and the Olympic Marine community in Greece, which still operates as a major Mediterranean yachting hub. Technical data and original design intent are often referenced through the archives of Ted Brewer Yacht Design, where the Adventure series is recognized for its contribution to mid-century cruising standards.

The Verdict

Pros:

• Exceptional heavy-weather stability and sea-kindly motion.
• High-quality traditional teak joinery and interior volume.
• Center-cockpit layout provides a private, spacious aft cabin.
• Extremely robust hull layup suitable for offshore voyaging.

Cons:

• Sluggish performance in light air (under 10-12 knots).
• High maintenance requirements for aging teak decks and original systems.
• Limited maneuverability in tight marinas due to the long keel and prop walk.
• Large wetted surface area increases annual bottom maintenance costs.
