The Hurley 20, designed by Ian Anderson and introduced in the late 1960s, was engineered as a robust "pocket cruiser" that filled the niche between the entry-level Hurley 18 and the legendary Hurley 22. Launched during the height of Hurley Marine Ltd.’s production era in Plymouth, the Hurley 20 was a response to the growing demand for a trailerable yet seaworthy vessel capable of coastal passage-making. While it shares the "family resemblance" of Anderson’s other designs—characterized by a stepped coachroof and a traditional transom—the 20 was a distinct hull specifically molded to maximize internal volume without sacrificing the heavy-weather stability the brand was known for. Approximately 450 to 500 units were produced, primarily featuring GRP construction that adhered to Lloyd’s specifications, ensuring many remain in active service today.

Sailing Performance & Handling

The sailing characteristics of the Hurley 20 are defined by its high ballast-to-displacement ratio, often approaching 50%, which results in an exceptionally stiff and forgiving platform. Unlike modern, light-displacement 20-footers that rely on crew weight for stability, the Hurley 20 feels like a much larger yacht underfoot. According to technical archives from the Hurley Owners Association, the boat was offered in both fin keel and twin (bilge) keel configurations. The fin keel version offers superior tracking and pointing ability, while the bilge keel variant was designed for the tidal estuaries of the UK, allowing the boat to dry out upright on a mooring.

Under sail, the boat is not particularly fast in light airs due to its conservative sail area-to-displacement ratio, but it excels when the wind rises above 15 knots. Handlers often note that the boat maintains a neutral helm longer than its peers, a trait inherited from its larger sibling, the Hurley 22. Its narrow beam (approximately 7'1") and traditional long-keel influence mean it slices through choppy coastal waters rather than slamming over them, providing a level of "sea-kindliness" rarely found in the sub-22-foot category.

Interior Comfort & Variations

For a 20-foot vessel, the interior layout is remarkably functional, though it reflects the era's focus on utility over luxury. The cabin provides four berths: a V-berth in the forepeak and two long quarter-berths that extend aft under the cockpit seats. Headroom is limited to approximately 4'8", necessitating a "crawling" or seated lifestyle while below decks. Most models were equipped with a small galley area featuring a two-burner spirit or gas stove and a simple manual water pump.

Variations in the interior primarily concern the placement of the chemical or marine toilet, which is typically located under the V-berth cushions. Unlike larger models in the Hurley range, there are no structural bulkheads separating the main saloon from the forepeak, which creates an open, albeit cramped, feel. The sibling models, such as the Hurley 22, provide significantly more headroom and a dedicated "heads" area, but the Hurley 20 remains a favorite for solo sailors or couples who prioritize a compact footprint for easier trailering and lower slip fees.

While the Hurley 20 is often overshadowed by the Hurley 22—which gained international fame when it was used for solo Atlantic crossings—the 20 holds a respected place in the "Small Ships" community. It is frequently cited in British maritime literature as the quintessential starter cruiser for those learning the ropes of coastal navigation in the English Channel. Its cultural footprint is most visible within the "Micro-Cruising" movement on digital platforms, where owners document extensive restoration projects and coastal adventures, praising the hull’s ability to survive conditions that would overwhelm modern "gin palace" day-sailers.

Known Issues & Buyer’s Checklist

Prospective buyers of a Hurley 20 should approach the purchase with a focus on structural integrity, as many of these vessels are now over 50 years old.

  1. Deck Compression: A common "gotcha" for this model is the compression of the deck core beneath the mast step. If the internal support post (if fitted) or the deck itself shows signs of sagging, it can lead to rigging tension issues.
  2. Osmosis: Early GRP layups from the late 60s and early 70s are prone to osmotic blistering. While rarely structural on a hull this thick, it is a significant factor in valuation and maintenance.
  3. Outboard Well/Transom: Many Hurley 20s utilize an outboard motor for auxiliary power. The mounting bracket or the integrated outboard well (depending on the specific production run) should be checked for stress fractures or delamination caused by oversized modern four-stroke engines, which are heavier than the two-strokes of the era.
  4. Chainplates: The stainless steel chainplates are known to leak, which can lead to moisture ingress into the side decks. Checking for "tea staining" or water marks on the interior GRP is essential.

Community & Resources

The primary hub for technical support, original brochures, and parts sourcing is the Hurley Owners Association. This organization is one of the most active classic boat associations in the UK, maintaining a comprehensive database of sail plans and historical production data. Owners also frequently congregate on technical forums such as CruisersForum to discuss modifications, such as converting the original iron ballast to encapsulated systems or upgrading the rudder pintles.

The Verdict

The Hurley 20 is a "big boat in a small package," offering a level of security and build quality that modern entry-level sailors rarely encounter. It is an ideal choice for the budget-conscious sailor who values seaworthiness over standing headroom.

Pros:

  • Exceptional stability and stiffness for its size.
  • Strong, thick GRP hull capable of handling significant sea states.
  • Available in bilge keel versions for shallow-draft or tidal moorings.
  • Highly active and supportive owner community.

Cons:

  • Very limited headroom (less than 5 feet).
  • Underpowered in light wind conditions.
  • Prone to "old boat" issues like osmosis and deck leaks.
  • Cramped for more than two adults for extended cruising.
