Design Brief & Intent
The Armor 660 is a classic manifestation of the "Masurian School" of yacht design, born in the lake-rich regions of Poland where shallow drafts, easy trailering, and maximum interior volume are paramount. While competing designs of the late 1990s often forced buyers to choose between the spartan interior of a performance sportsboat or the heavy, un-trailerable nature of a traditional keelboat, the Armor 660 attempts to bridge this gap.
Inside, the boat defies its 21.65-foot length overall (LOA). The interior joinery and molding quality are respectable for a mass-produced vessel of this era, relying on a structural GRP inner liner finished with warm wood trim to mitigate the cold feel typical of small fiberglass cabins. Its layout is remarkably civilized: it features a dedicated galley area with a two-burner stove, a manual or pressurized fresh-water sink, a chemically operated marine head housed in a separate, private compartment, and berths for up to four or five adults via a convertible V-berth, a double aft transverse berth, and a single settee. This high level of interior accommodation is made possible by a high-freeboard hull design and a raised coachroof, giving the boat unparalleled "big-boat" liveability compared to sleek but cramped traditional trailer-sailers.
Variations & Configurations
Throughout its production, the vessel was configured with different keel and drivetrain arrangements to suit regional European markets:
- Swing Keel (Ballasted Dinghy): This is the most common configuration, particularly on the French and Polish waterways. It features a pivoting metal centerboard that retracts completely into a shallow keel stub. This layout reduces the minimum draft to an ultra-shallow 1.48 feet (0.45 meters), making beaching, drying out on tidal moorings, and ramp-launching exceptionally simple. When fully extended, the board drops to 5.05 feet (1.54 meters) to provide lateral resistance.
- Wing Keel: A fixed-keel variant designed for coastal owners who did not require trailering or shallow-water beaching. This configuration trades trailer convenience for simplified maintenance, eliminating the pivoting board machinery and lowering the center of gravity.
- Outboard Bracket vs. Engine Well: The vast majority of Armor 660s utilize an outboard engine (typically between 5 and 9.9 horsepower) mounted either in a dedicated cockpit well or on a heavy-duty transom bracket.
- The "Prestige" Inboard Edition: In the UK market, under the Europa TS240 badge, a rare premium tier was sold featuring a small, single-cylinder Nanni diesel inboard engine. This variant provided unmatched motor reliability and battery charging capacity, though at the expense of added weight and slightly more complex maintenance.
Sailing Performance & Handling
With a displacement of 3,351 pounds, a waterline length of 19.68 feet, and a displacement-to-length (Disp/LWL) ratio of 196.27, the Armor 660 sits squarely in the moderate-displacement category. On the water, this translates to a stable yet lively motion. The boat's comfort ratio of 15.17 reflects its light overall mass; it will feel active and responsive in a seaway, and motion in short, steep waves will be felt more keenly than in a heavy-keel design.
A capsize screening ratio of 2.23 underscores that this boat is intended as a coastal and inland cruiser rather than an offshore passage-maker. Under its fractional sloop rig—which utilizes a modest headsail for effortless single-handed tacking—the Armor 660 is exceptionally fast and slippery in light air (under 10 knots of wind). Its clean hull lines and generous waterline length help it easily achieve its theoretical maximum hull speed of approximately 5.9 knots.
However, the design's high freeboard and coachroof introduce significant windage ("fardage"). Combined with a ballast-to-displacement ratio of 27.63%, the boat is relatively tender. It heels quickly when the breeze rises above 12 to 15 knots. Seasoned owners agree that early reefing is essential to maintain control and comfort; once reefed down, the boat is surprisingly seaworthy and tracks well, but driving it over-canvased in a blow will quickly round it up. Additionally, in swing-keel configurations, the boat can feel notably tender and roll at anchor if the heavy centerboard is fully retracted.
Known Issues & Triage
For prospective buyers on the brokerage market, there are several model-specific technical areas that require close inspection:
- Outboard Well Seal Degradation: For units equipped with the engine well, water ingress into the bilge is a common complaint. The polyurethane seal (originally Sikaflex) around the hull-to-well joint can degrade over time, particularly if a previous owner was aggressive with high-pressure washers. Water leaking here bypasses the cockpit drains and goes straight into the cabin bilge.
- Swing Keel Cable and Pivot Pin: The lifting mechanism for the swing keel consists of a stainless-steel cable, a winch, and a bronze or steel pivot pin. This system operates in a harsh, oxygen-deprived underwater environment. The cable is prone to fraying at the attachment eye, and the pivot pin can wear out, causing a noticeable "clack" when the boat rolls. Inspecting these components requires suspending the hull on a crane or a dedicated high trailer.
- Deck Gelcoat Crazing and Core Wetness: Like many production boats of this era, the balsa-cored decks are susceptible to moisture intrusion if hardware (such as stanchion bases, cleat backings, or the mast step) has not been periodically re-bedded. The high windage of the tall rig can also place high stresses on the chainplates, which must be monitored for hairline cracks or water staining on the bulkheads below.
- Rudder Blade Play: The transom-hung rudder is subject to significant load. The rudder gudgeons, pintles, and the cassette holding the lifting rudder blade must be examined for stress fractures and excessive play, which can lead to a heavy, unresponsive helm.
Modernization & Upgrades
Modern owners of the Armor 660 focus their refit budgets on weight reduction, electrical independence, and safety:
- Electric Propulsion Conversions: Because the boat's light displacement makes it highly compatible with electric outboards, many owners are replacing aging, heavy petrol outboards with units like Torqeedo or ePropulsion. This change eliminates the safety hazard of carrying gasoline in the cockpit lockers and frees up weight at the transom.
- Lithium (LiFePO4) Electrical Systems: The original electrical setup on these boats was rudimentary, often utilizing a single, small 54 Ah lead-acid battery. Modernizing to a single 100 Ah LiFePO4 battery combined with a flexible 100W solar panel mounted on the coachroof or a custom aft arch provides complete energy independence for the cabin lights, VHF, and basic instruments.
- Running Rigging Lead-Back: The factory rig did not always lead all halyards and reefing lines back to the cockpit. Upgrading the deck organizers and adding a series of spinlocks on the cabin top allows for safer, single-handed sailing without needing to go on deck in rough weather.
The Verdict
The Armor 660 is an exceptionally clever, space-efficient cruiser that excels at pocket-budget coastal hopping and lake sailing. While it is not designed to battle heavy blue-water offshore conditions, it provides an unparalleled level of cabin comfort and standard amenities in a package that can still be easily towed behind a standard mid-sized SUV.
Pros:
- Remarkable interior volume with a private heads compartment and sleeping capacity for up to five.
- The highly versatile swing keel allows for shallow-water exploration, beaching, and simplified ramp trailering.
- Excellent sailing performance and responsiveness in light-to-moderate air.
- At under 22 feet, the boat is highly cost-effective to store, slip, and maintain.
Cons:
- Relatively tender design that requires early reefing when the wind climbs past 12-15 knots.
- High freeboard and coachroof introduce significant windage, making close-quarters marina maneuvers under outboard power challenging in a blow.
- Swing keel pivot assembly and lifting cable require regular underwater inspection and maintenance.
