Trailertri 680 Information, Review, Specs

Sailing Performance & Handling

The sailing characteristics of the Trailertri 680 are defined by its high power-to-weight ratio and the inherent stability of the trimaran platform. Unlike monohulls of a similar length, the 680 does not rely on heavy lead ballast; instead, it utilizes its 18-foot beam to create a massive righting moment. This allows the boat to carry a generous sail plan, often resulting in double-digit speeds that far outpace contemporary 22-foot cruisers.

On the water, the 680 is known for its "sea-kindliness," a term often used by owners to describe how the boat remains level even in gusty conditions. Because the amas provide immediate buoyancy as the boat heels, the "white-knuckle" sensation common in narrow monohulls is largely absent. According to historical technical notes from the designer, the boat tracks exceptionally well due to its deep daggerboard, which also allows for impressive upwind performance. Handling is reported to be light and responsive, almost akin to a large dinghy, though the 680 remains remarkably dry in most conditions due to its flared hull and buoyancy in the bows.

Interior Comfort & Variations

For a vessel under 23 feet, the Trailertri 680 offers a surprisingly functional interior, though it is categorized as a "pocket cruiser" rather than a long-term liveaboard. The main cabin typically features a V-berth forward and two narrow settee berths in the saloon area. Because the folding mechanism occupies space on the exterior, the interior remains unobstructed, providing roughly 4' 10" of headroom—standard for a boat focused on aerodynamics and low-profile trailering.

The model saw several variations during its production lifespan. The most significant sibling is the Trailertri 720, which is essentially a 680 with an integrated transom extension to provide a larger cockpit and improved buoyancy aft. Another close relative is the Farrier Tramp, a 19-foot production version that utilized similar folding logic but on a smaller scale. In terms of materials, while the plans specified cedar strip or plywood, some later kit versions incorporated foam-core composites, which significantly reduced weight and increased the boat’s "unsinkable" characteristics.

Known Issues & Buyer’s Checklist

Prospective buyers must approach the Trailertri 680 with a "builder-first" mentality. Since many were home-built, the quality of the epoxy saturation and joinery can vary wildly between hulls.

1. Folding Hardware: The stainless steel brackets and pivot bolts that facilitate the Farrier Folding System are under high load. Inspect these for hairline fractures or "slop" in the movement. Replacement hardware can be difficult to source and may require custom fabrication.
2. Core Integrity: For plywood or cedar-strip builds, moisture ingress is the primary enemy. Pay close attention to the areas where the folding struts attach to the amas and the main hull, as these penetrations are common sites for rot if not properly sealed with epoxy.
3. Daggerboard Trunk: High-speed groundings can crack the daggerboard trunk or the surrounding hull structure. Check for signs of stress cracking or previous fiberglass repairs around the trunk base.
4. Ama Buoyancy: Older boats may have developed leaks in the amas. It is advisable to perform a pressure test or a thorough visual inspection of the hatches and seams to ensure the outriggers remain watertight.

Community & Resources

The Trailertri 680 benefits from a dedicated global following centered around the Farrier and Corsair multihull communities. The Farrier Marine website remains a vital touchpoint for the history and technical specifications of the design. Additionally, the F-boat community on various technical platforms provides a wealth of shared knowledge regarding modifications and repairs specific to the early Trailertri series.

The Verdict

The Trailertri 680 remains a premier choice for sailors who prioritize speed and trailerability without sacrificing the ability to spend a weekend on the water.

Pros:

• Exceptional Versatility: The folding system allows for easy trailering and standard slip storage.
• High Performance: Easily outperforms monohulls twice its size in moderate winds.
• Safety: The trimaran configuration offers immense stability and shallow draft for beaching.

Cons:

• Variable Build Quality: As a predominantly home-built boat, thorough surveying is mandatory.
• Limited Headroom: The low-profile cabin is not suited for tall sailors or extended cruising.
• Age: Many units now require significant refits of standing rigging and folding hardware.
