Design Brief & Intent
Petterson's primary objective with the King's Cruiser 33 was to deliver a highly seaworthy, comfortable cruiser that could also perform respectably under the prevailing International Offshore Rule (IOR) handicapping system. To achieve this, the hull features a moderately deep fin keel paired with a robust, skeg-mounted rudder—a departure from the full-keel configurations of earlier Scandinavian designs, prioritizing maneuverability and speed without sacrificing directional tracking.
One of the boat's most striking visual signatures is its near-flush deck. The low-profile cabin trunk merges seamlessly into wide, uncluttered side decks, providing an exceptionally secure working platform for the crew. This flush-deck design allowed the builders to maximize interior volume. Below deck, the boat reflects the golden era of Finnish cabinetmaking. The interior is characterized by warm, hand-finished mahogany joinery and a traditional, highly functional layout. Forward, a classic V-berth comfortably accommodates two adults. A compact head to starboard and a hanging locker to port divide the forward cabin from the main saloon. The saloon features two long longitudinal settees that flank a central folding table, easily seating six and doubling as comfortable sea berths. A well-proportioned galley sits to port of the companionway, while a dedicated navigation station and a generous quarter berth occupy the starboard quarter. The fit-out is cozy and secure, with ample handholds and storage lockers designed to keep gear in place when the boat is pressed hard.
Sailing Performance & Handling
With a displacement of 9,480 pounds and a substantial cast-iron fin keel of over 4,400 pounds, the King's Cruiser 33 boasts an impressive ballast-to-displacement ratio of 46.52 percent. This high ratio makes the boat exceptionally stiff and stable, enabling it to carry a full press of sail long after lighter, modern cruisers have been forced to reef. The boat’s capsize screening formula of 1.94 indicates a highly seaworthy hull form with a strong righting moment, making it well-suited for serious blue-water voyaging and offshore passages.
With a displacement-to-length ratio of 306.14 and a comfort ratio of 24.54, the King's Cruiser 33 behaves with the predictable, reassuring motion of a heavy-displacement cruiser. It carves through heavy head seas with momentum-driven authority, refusing to slam or shudder in a seaway. Under sail, the masthead sloop rig has a moderate sail area-to-displacement ratio of 15.75. In light air (under 10 knots), the heavy hull requires a large genoa and some patience to build speed, as it is not a light-wind flyer. However, once the breeze fills in past 12 to 15 knots, the boat truly enters its element. At the helm, it tracks remarkably straight—almost as if on rails—relying on its deep fin and skeg to maintain course with minimal helmsman fatigue.
Known Issues & Triage
Despite its legendary build quality, any vessel that is half a century old will present age-related vulnerabilities that prospective buyers must evaluate:
- The "Fiskars Smile": Similar to the keel-joint issues seen in other builders of this era, the King's Cruiser 33 can develop a hairline crack at the hull-to-keel joint. Over time, water can seep into the joint, causing the cast-iron keel to scale and rust, which exerts outward pressure on the fiberglass. The accepted repair involves grinding back the joint, treating the cast iron with a rust-inhibiting epoxy primer, and re-bedding the joint with a high-strength, flexible polyurethane sealant like Sika 291 before torquing the heavy keel bolts back to factory specifications.
- Deck Core Rot and Mast Compression: The flush deck is constructed as a sandwich using an end-grain balsa core. If water penetrates the sealant around deck hardware, shroud chainplates, or the deck-stepped mast shoe, it will rot the underlying balsa. This leads to soft spots, deck flexing, and eventual compression of the deck under the downward load of the mast. Triage requires cutting away the upper fiberglass skin in the affected area, digging out the rotted balsa, replacing it with solid fiberglass or high-density closed-cell foam, and re-laminating the deck.
- Propeller Walk in Reverse: Under power, the original Volvo Penta engine installations suffer from an incredibly strong propeller effect (prop walk). When reversing, the boat exhibits a stubborn pull to port and can be exceptionally difficult to steer in a straight line. While not a structural failure, it is a significant handling quirk that requires practice to master.
- Cockpit Drains: The cockpit is deep, secure, and highly protected, but the factory drains are somewhat small in diameter and sit close to the waterline. In heavy following seas or torrential downpours, the cockpit can be slow to drain. Many owners replace the original fittings with larger-diameter drains and upgraded seacocks for safety.
Modernization & Upgrades
Over the decades, a dedicated owners' community has established several standardized modernization routines to keep these classic cruisers viable for modern sailing:
- Engine Repowering: The original 25-horsepower Volvo Penta MD2B diesels are now long past their intended service life. Many active hulls have been repowered with modern, lightweight three-cylinder diesels, such as the 30-horsepower Volvo Penta MD2030, Bukh engines, or Yanmar 3GM30F. These newer powerplants offer superior reliability, better fuel economy, and readily available replacement parts.
- Feathering Propellers: To counteract the severe prop walk in reverse and to reduce drag under sail, the installation of a multi-blade feathering or folding propeller is a highly recommended upgrade. It dramatically improves low-speed maneuvering in tight marinas.
- DC Electrical Systems and Solar Integration: The original wiring and glass-fuse panels are generally obsolete. Veterans of the model typically install modern marine-grade wiring, high-output alternators, and lithium iron phosphate battery banks. The wide, near-flush deck of the King's Cruiser 33 provides an ideal surface for mounting low-profile, walk-on flexible solar panels, helping cruising couples achieve complete energy independence.
- Hull Liner Refinishing: The 1970s factory interior made heavy use of molded orange-brown fiberglass liners. Modern refits often involve painting these surfaces in bright off-whites or lining them with modern marine vinyl and mahogany slats to brighten and open up the cabin.
Market Snapshot & Economics
The King's Cruiser 33 occupies a unique space on the international brokerage market. It is highly sought after by budget-conscious traditionalists who appreciate Scandinavian craftsmanship but cannot afford the premium demanded by Hallberg-Rassy, Najad, or Swan yachts of the same vintage. Most of the remaining fleet resides in northern Europe, particularly around the Baltic and North Seas, making them relatively scarce in North America.
From an economic perspective, these boats trade at a highly accessible entry-level valuation, offering an extraordinary amount of structural integrity for the money. However, the economics of a purchase must be weighed carefully against the cost of deferred maintenance. Because the hull is exceptionally thick and hand-laid—virtually immune to the structural osmosis issues that plague thinner layups of the era—the base platform is remarkably sound. Yet, a buyer facing a combination of an original engine, soft deck sections, and tired rigging can easily invest twice the purchase price of the vessel into a comprehensive refit. For a skilled DIY sailor, the King's Cruiser 33 represents one of the most rewarding and structurally secure restoration projects available in the 33-foot class.
The Verdict
The King's Cruiser 33 is a rugged, beautifully built Baltic classic that offers exceptional seaworthiness, predictable handling, and timeless Scandinavian charm. While it is not a light-air racer and possesses handling quirks under power, its thick GRP hull, high ballast ratio, and comfortable motion make it an incredibly safe and capable companion for coastal cruising or offshore passage-making.
