Searunner 34 Information, Review, Specs

Sailing Performance & Handling

The Searunner 34 is defined by its cutter rig and a deep, retractable centerboard. Unlike many modern production catamarans that rely on fixed fins, the Searunner’s centerboard allows for exceptional windward performance while providing the safety of a shallow draft for gunkholing. Under sail, the boat is known for its "sea-kindliness"—a term Jim Brown frequently used to describe a multihull’s ability to move through water without the harsh, jerky motion often found in wider, flatter designs.

Technical assessments from the OutRig! Project emphasize that the Searunner’s amas (outer hulls) are designed with a high prismatic coefficient. This prevents the leeward bow from burying when pressed hard, a critical safety feature for offshore passage-making. While the boat is significantly faster than monohulls of the same length—frequently averaging 7 to 9 knots on a passage and capable of bursts over 15 knots—its primary strength is stability. The wide beam and low center of gravity provided by the centerboard trunk (which is integrated into the cockpit sole) make the 34 a stable platform in a seaway. However, sailors should be aware of "hobby-horsing" in short, steep chop, a characteristic common to older multihull designs with significant rocker in the main hull.

Interior Comfort & Variations

The Searunner 34 features a "center-cockpit" layout that fundamentally divides the living spaces into two distinct zones. The central cockpit is deep and protected, located directly over the centerboard trunk, which places the crew’s weight in the most stable part of the boat. This layout results in the "Stern Castle," a private aft cabin that serves as the owner’s suite or a quiet retreat during long watches.

Moving forward from the cockpit leads to the main saloon, which typically houses the galley and dinette. Unlike the wide-open bridgedeck saloons of modern catamarans, the Searunner 34's interior is more traditional and narrow, contained within the main hull. To maximize space, the design incorporates "wing berths"—sleeping platforms that extend over the water between the main hull and the amas. These berths are often cited by owners as the most comfortable places to sleep at sea due to the minimal motion at the boat's extremities. Siblings in the series, such as the Searunner 31, offer a similar layout but with significantly less headroom and storage capacity, making the 34 the minimum size many consider practical for long-term liveaboard cruising.

Popular Mentions & Media

The Searunner series gained international fame through Jim Brown’s own voyages and his extensive writings, including the book The Case for the Cruising Trimaran. His personal boat, Scrimshaw, was a Searunner 31, but the 34 benefited from the same design philosophies that Brown popularized through his "Searunner Catalog" and construction manuals. The 34 specifically is often featured in technical discussions regarding the evolution of cold-molded wooden multihulls, appearing frequently in maritime history retrospectives provided by Ocean People and other multihull heritage organizations.

Known Issues & Buyer’s Checklist

Because the Searunner 34 was primarily an owner-built design, the build quality can vary significantly between individual hulls. Prospective buyers must prioritize a structural survey focusing on several critical areas:

• Plywood Rot: Any Searunner not meticulously encapsulated in epoxy is susceptible to rot, particularly in the underwing areas and near the chainplates. Freshwater leaks from deck hardware often migrate into the plywood core, leading to delamination.
• Centerboard Trunk: The trunk is a structural member but is also a common source of leaks. Inspect the pivot pin and the winch mechanism for wear, as a failure here can compromise the boat’s windward ability and create significant drag.
• Underwing Pounding: In certain sea states, the flat surfaces of the underwings can "slam" or "pound" against wave tops. While usually a comfort issue rather than a structural one, persistent heavy pounding can lead to stress cracks in the hull-to-wing joints.
• Rig Tension and Bulkheads: Check the alignment and attachment of the main bulkheads to the hull. Because the cutter rig places significant load on the mast step and chainplates, any movement in the bulkheads can lead to rig instability.

Community & Resources

The Searunner community remains one of the most dedicated "cult" followings in the sailing world. Technical support and original design philosophy are primarily preserved through the OutRig! Project, which serves as a technical wiki and historical archive for Jim Brown’s work. Additionally, John Marples, a long-time associate of Brown, continues to provide technical advice and plans for the "Seaclipper" series, which evolved from the Searunner lineage.

The Verdict

The Searunner 34 is a classic "sailor's multihull," offering a level of seaworthiness and feedback that modern, high-volume production cats rarely match. It is an ideal choice for the budget-conscious voyager who values performance and safety over "condo-maran" interior volume.

Pros:

• Exceptional stability and safety record for offshore cruising.
• Cutter rig and centerboard provide excellent versatility in varied wind and depth conditions.
• Private aft "Stern Castle" offers superior separation for crew or owners.
• Affordable entry point into the world of blue-water multihull cruising.

Cons:

• Maintenance intensive due to plywood/epoxy construction.
• The center-cockpit layout requires going "outside" to move between the forward and aft cabins.
• Sensitive to weight; overloading significantly degrades sailing performance.
• Limited interior volume compared to modern catamarans of the same length.
