Kadey-Krogen 52

Welcome to SEA HORSE, a Class A, full displacement, long range trawler. Since her inception, SEA HORSE has been the sanctuary of two sets of meticulous, full-time live-aboard owners. She is presented in exemplary condition and arguably shows as good today as the day she was launched. The current owners have maintained a standard of technical rigor and aesthetic excellence that matches the unparalleled degree set by her original stewards. Purpose-built and outfitted for serious blue-water passage-making, she is a fortress of self-sufficiency, equipped with every system required for an independent life on the hook, no matter the destination.

Her pedigree is backed by thousands of miles of proven performance and a reputation for excellence that resonates far beyond the Kadey-Krogen community. Her original owners established a foundation of offshore success, spending five months annually off-grid in the Bahamas then continuing north and south along the U.S. East Coast and North Atlantic. Since 2024, her current owners have seamlessly upheld this legacy, navigating the Eastern Seaboard, the Great Lakes, and successfully completing the Great Loop via the Mississippi.

SEA HORSE does not just promise adventure; she has lived it. Having transitioned her owners safely through the most iconic North American waterways, she stands ready for her next mission. She is offered for sale only as her owners move toward their next adventures, presenting a turnkey opportunity for the discerning cruisers who demand a vessel that is as rugged as it is refined.

Showings by appointment only to pre-qualified buyers. 

CONSTRUCTION

Hull and superstructure molds from high-grade female tooling.

Hull construction includes use of USA-made, Cook® gel coat. Hand-Laid Knytex® fiberglass construction with closed-cell PVC sandwich core used in topsides. Solid fiberglass below waterline with blister-resistant vinylester resin utilized on first two laminates below the waterline, with aramid fiber/FRP reinforcements.

Superstructure includes Knytex® and mat (in combination with Corecell® cores) and surface mats for print-through reduction.

Teak aft and side deck. Boat and fore decks have GripTex® non-skid finish. Bulwark has molded plank lines with gel coat finish.

Polyurethane formulated marine sealants used at hull-to-deck, boat deck joints and exterior fittings.

Marine-grade plywood bulkheads with molded fiberglass hat section stringers.

Interior finished with handcrafted solid teak and veneers.

 

SALOON

Step into the expansive saloon through dual weathertight aluminum doors, which feature a retractable screen to bridge the gap between the interior and the teak aft deck. The starboard side is anchored by a generous U-shaped settee with hidden storage and a versatile cherry hi-lo table—sturdily secured for offshore travel and capable of seating eight for dinner. To port, a pair of reclining chairs offers a quiet retreat near the forward bookcase and bar. The space is exceptionally bright, featuring five large opening windows with custom valances that provide superb cross-ventilation. For quiet evenings, a 48" Samsung UHD Smart TV rises on a lift behind the settee, complemented by Apple TV and a Blu-Ray player.

GALLEY

Located forward on the starboard side, the galley seamlessly integrates with the saloon while remaining distinct, separated by a custom granite counter and backsplash. This 52' boasts a more open feel than any in its class; by removing traditional overhead cabinetry, the line of sight is completely unobstructed. Storage capacity is actually increased through a clever redesign: four Sub-Zero drawer units replace bulky upright units, creating deep drop-down storage and additional preparation surfaces. To port, a massive cabinetry suite offers a comprehensive pantry, drawers, and a dedicated buffet counter. A welded aluminum Dutch door provides direct access to the side deck for easy provisioning, all set against beautiful, warm cherry and ash flooring.

Major components in the galley include:

Sub Zero drawer refrigerators and freezers (2 each, 4 total)

GE® microwave/convection oven

Blue Star 4 burner stove/oven

GE® Dishwasher

Elkay® Stainless steel double basin galley sink with Grohe® faucet                             

Slide out double trash bin for recycling convenience

Pantry across from galley for easy access to storage

 

MASTER STATEROOM

The forward master stateroom is a bright, tranquil retreat centered around a custom island king berth. Six points of ventilation—four large stainless steel opening ports and two overhead hatches with Oceanair Skyscreens—ensure the space feels expansive and airy. For added comfort, dual fans provide a gentle breeze. Storage is exceptionally well-planned, featuring deep drawers beneath the berth and a cavernous area accessed via a pneumatic mattress lift. The suite is completed by two deep hanging lockers and a seven-drawer dresser beautifully accented with custom LED lighting.

MASTER ENSUITE HEAD

The private ensuite head, located to the aft port side of the master stateroom, is an excellent example of functionality aboard a boat. It features a spacious stall shower with a glass door and integrated molded seat, complemented by a granite-topped vanity with premium Grohe fixtures. The space is equipped with a full-sized Dometic porcelain freshwater toilet and ample storage, including two mirrored medicine cabinets and a dedicated linen locker. Two large opening stainless steel ports—one above the vanity and one in the shower—ensure the room is always bathed in natural light and perfectly ventilated.

STARBOARD GUEST STATEROOM

Located to starboard and aft of the master, the guest stateroom features a rare, custom walk-around queen bed. This thoughtful layout is ideal for hosting guests or serving as a preferred midships berth for the owners during heavier sea states. The room is exceptionally functional, offering large drawers beneath the bed and additional cavernous storage accessed via a pneumatic lift. Two oversized opening portholes flood the space with natural light and provide excellent ventilation, making this cabin feel as inviting as a master suite.

STARBOARD GUEST HEAD (DAY AND ENSUITE)

The guest head, situated forward of the guest cabin, is designed with a dual-entry configuration that allows it to serve as both a private ensuite and a convenient day head. Guests in the starboard cabin can access the space directly from their stateroom, while a second door to the companionway provides easy access for visitors (or the third cabin) without disturbing the sleeping quarters. This well-appointed head features a granite-topped vanity, a household-sized Dometic porcelain toilet, and a separate shower stall with a glass door and molded seat. A stainless steel opening port within the shower ensures the space is always bright and well-ventilated.

PORT DEN (THIRD STATEROOM)

Located to port and forward of the galley, this versatile den serves as a peaceful retreat that easily transforms into a third stateroom. The space features a large, comfortable settee that pulls out to accommodate guests, while a recessed ceiling track with a privacy curtain allows the area to be partitioned off from the companionway when needed. Storage is plentiful, with drawers beneath the berth and dual end tables. For younger travelers, a clever Pullman berth on the forward bulkhead provides a cozy sleeping nook, which also doubles as a convenient pull-down luggage rack. The area is bathed in natural light from two large stainless steel ports and accented by warm LED overhead lighting. Just forward in the companionway, separate Bosch washer and dryer units are discreetly housed behind vented cherry doors.

PILOTHOUSE AND ELECTRONICS

Just a few steps up from the main deck, the pilothouse is the ship's nerve center.  The helm is built for serious operation, featuring a wide and low command center for quick and easy access to the main controls, switches and electronics.  SEA HORSE also features a pair of heavy-duty LeBroc chairs with integrated joystick controls so the captain and mate can run the show side-by-side. Behind the controls, an Ultraleather L-shaped settee and folding pedestal table provide a solid workspace or an additional place to dine. On long hauls, the settee converts into a double watch berth. Dual Dutch doors on the port and starboard sides offer quick access to the decks and serious airflow. For docking in tight quarters, the Portuguese bridge is outfitted with twin wing stations, giving the captain total command and visibility from either side of the ship.  SEA HORSE was engineered for scalability, allowing owners to integrate additional components based on their specific cruising requirements and range.

For protection from the elements, the Sunbrella Bimini is equipped with side and aft roll-down shades, allowing you to easily adjust for sun or breeze.

Tucked just behind the helm is a practical summer kitchen, perfect for outdoor meals. It comes fully equipped with a SeaStar propane BBQ, a stainless steel sink with hot and cold water, and ample storage for supplies.
