Vivacity 20 Information, Review, Specs

Sailing Performance & Handling

As a small, heavy-displacement cruiser for its length, the Vivacity 20 is characterized more by its stability and "big boat" feel than by raw speed. With a displacement of approximately 2,000 lbs and a ballast ratio often exceeding 40% depending on the keel configuration, the boat handles heavy weather with a composure that belies its 20-foot length. The twin-keel (bilge keel) version is the most common variant found in the UK and Europe, allowing the vessel to take the ground upright in tidal moorings.

While the twin-keel configuration introduces additional drag and reduces pointing ability compared to the rarer fin-keel model, it provides a shallow draft of just 2.5 feet, making it an exceptional vessel for "gunkholing" in shallow creeks. The masthead rig is robust, though the boat's relatively low Sail Area to Displacement (SA/Disp) ratio suggests it requires a stiff breeze to truly come alive. Owners often report that the boat is remarkably stiff, but like many short-waterline vessels with a wide beam, the weather helm can become pronounced if the mainsail is not reefed early. Technical specifications preserved by the Alacrity and Vivacity Owners Association confirm that while not a racing yacht, its sea-kindliness made it a favorite for crossing the English Channel and navigating the North Sea.

Interior Comfort & Variations

Despite its modest dimensions, Russell Marine marketed the Vivacity 20 as a four-berth cruiser—a claim that is best suited for two adults or a young family. The interior layout typically features a V-berth forward and two quarter berths extending aft under the cockpit seats. A small galley area, usually consisting of a two-burner stove and a rudimentary sink, is situated midships.

The Vivacity 20 was a direct evolution of the Alacrity 19. While both shared similar hull characteristics, the Vivacity 20 utilized a revised deck mold to provide increased headroom and a more usable cabin volume. This model eventually paved the way for the Vivacity 21 (also known as the 650), which featured a more streamlined coachroof. The interior finishes are unapologetically utilitarian, utilizing molded GRP liners with teak trim. This construction method has proven durable over decades, though the lack of insulation in these early hulls can lead to condensation issues in colder climates.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Vivacity 20 with an eye toward the structural realities of 50-year-old fiberglass construction. High-signal areas for inspection include:

• Deck Core Integrity: Like many early GRP boats, the balsa or plywood core in the deck can suffer from water ingress. Particular attention should be paid to the areas surrounding the chainplates and stanchion bases, where hairline cracks often allow moisture to rot the internal core.
• Keel-to-Hull Joint: On twin-keel models, the stresses of "taking the ground" repeatedly on tidal moorings can lead to structural fatigue at the keel stubs. Buyers should look for "smiles" or cracks at the joint and check the internal floors for signs of stress or previous repair.
• Compression Post: The mast step sits directly atop the coachroof. Over time, high rig tension can cause the cabin top to sag if the internal compression post or supporting bulkhead has shifted or decayed.
• Rudder Hardware: The transom-mounted rudder is a simple design, but the pintles and gudgeons are prone to wear. Excessive play in the helm is often a sign that these bushings need replacement.

Community & Resources

The Vivacity 20 enjoys continued support through the Alacrity and Vivacity Owners Association, which remains the primary technical authority for the brand. This organization provides access to original brochures, rigging guides, and a community of owners who specialize in the restoration of these vintage Russell Marine vessels.

The Verdict

The Vivacity 20 is a rugged, honest little cruiser that prioritizes safety and versatility over modern performance. It remains an excellent entry-level boat for those who sail in tidal areas or require a trailerable vessel with genuine overnight capabilities.

Pros

• Exceptional stability for a 20-foot boat.
• Twin-keel option allows for easy maintenance and tidal mooring.
• Robust GRP construction that stands the test of time.
• Strong community support and technical documentation.

Cons

• Limited headroom and cramped quarters for more than two adults.
• Sluggish performance in light winds.
• Age-related issues like deck delamination are common.
• Noticeable weather helm if over-canvassed.
