The Independent 20 is a compact, performance-oriented masthead sloop produced by Independent Yachts Ltd. of Montreal, Canada. Introduced in 1978, the design was aimed at sailors seeking a spirited, trailerable boat capable of both competitive club racing and modest weekend cruising. While the company is perhaps better recognized for the slightly larger Formula 21, the Independent 20 serves as the foundation of the builder’s light-displacement philosophy. Built during an era of significant growth in the Canadian fiberglass industry, the vessel is identified by the Hull Identification Number (HIN) prefix "ZIY." Though production records are lean, approximately 35 to 50 units are estimated to have been completed before the model was largely superseded by its sibling, the Formula 21.

Sailing Performance & Handling

The Independent 20 is defined by its high power-to-weight ratio. With a displacement of approximately 2,000 lbs and a generous sail area, the boat features a Sail Area to Displacement (SA/Disp) ratio in the range of 22.1, placing it firmly in the category of high-performance daysailers. In light air, the Independent 20 is exceptionally responsive, often out-sailing larger, heavier cruisers. Its slender beam of 6 feet 8 inches contributes to an easily driven hull that tracks well but requires active trimming to maintain optimal heel angles.

Handling is generally described as agile and "dinghy-like." According to technical data compiled by regional PHRF handicap committees (such as the West Florida PHRF), the boat’s Displacement to Length (D/L) ratio sits near 153, categorizing it as a light-displacement racer. While this ensures quick acceleration, the boat has a reputation for being "tender" when the wind exceeds 12 to 15 knots. Owners typically report that early reefing is essential to maintain control and comfort. The original models featured a keel/centerboard configuration, though the "Independent 20-2" or Mk II variant was later introduced with a fixed fin keel to improve stability and windward performance.

Interior Comfort & Variations

For a 20-foot vessel, the Independent 20 offers a surprisingly functional interior, though it lacks standing headroom. The layout is optimized for short-term stays, typically accommodating up to four adults in a "camping-style" arrangement. The standard configuration includes a V-berth forward and two narrow quarter berths extending aft under the cockpit seats.

The interior is sparse, finished with a basic fiberglass liner and wood trim to save weight. Most units were equipped with a rudimentary galley area featuring a small sink and space for a portable stove. Storage is located beneath the berths, though it is limited by the hull's narrow entry. The transition to the 20-2 (Mk II) version primarily altered the exterior underwater profile with the fixed fin keel, but the interior layout remained consistent across the production run. This model shares significant design DNA with the Formula 21, which offered slightly more volume but a similar aesthetic of functional simplicity.

Known Issues & Buyer’s Checklist

Prospective buyers of an Independent 20 should prioritize a thorough inspection of the following technical areas:

  • Tiller and Rudder Assembly: Early models were noted for having relatively light-duty tiller pivots. Some owners have reported the need to reinforce or replace these pivots with heavier stainless steel components to handle the loads during high-wind sailing.
  • Deck Core Integrity: Like many fiberglass boats from the late 1970s and 1980s, the Independent 20 uses a cored deck construction. Buyers should check for soft spots around the chainplates, mast step, and pulpit mounts, where moisture ingress can lead to delamination.
  • Rigging and Tenderness: Because the boat is inherently light and carries a large rig for its size, the standing rigging and spreaders are under significant tension. Inspect all swage fittings for hairline cracks. The "tenderness" of the boat also means the reefing gear (hooks, lines, and winch placement) must be in excellent working order.
  • Centerboard Trunk (Original Models Only): For those looking at the original keel/centerboard variant, the centerboard trunk and pivot pin are critical points of failure. Check for leaks around the trunk and ensure the board operates smoothly without excessive lateral play.

The Verdict

The Independent 20 is a niche Canadian classic that offers a high-performance experience for sailors on a budget.

Pros

  • Exceptional Light-Air Speed: High SA/Disp ratio allows it to ghost along when other boats are becalmed.
  • Trailerability: Its narrow beam and light weight make it easy to transport and launch.
  • Handling: Very responsive helm that rewards active, skillful sailing.

Cons

  • Initial Stability: Can feel "tippy" or tender in heavy gusts, requiring early reefing.
  • Cramped Living Space: No standing headroom and limited storage make it unsuitable for extended cruising.
  • Niche Support: As a limited-production model from a defunct builder, technical support is limited to owner communities.
