The Stadtship 56 is a 56foot aluminum ocean cruiser conceived by Van de Stadt Design in collaboration with KM Yachtbuilders and an experienced engineerowner, and first delivered in 2005. Built as a practical, explorerstyle sloop, she pairs a retracting keel and twin lifting rudders with a hull and deck of welded aluminum, a configuration aimed squarely at longrange passagemaking where shoal draft and structural simplicity matter more than racing pedigree.

Design and Construction

The Stadtship 56's aluminum hull and deck are welded throughout, with large watertight bulkheads fore and aft and extra-thick insulation fitted against the shell anchor. At 24 tonnes displacement with a 5.05-meter beam and a lifting keel that draws as little as 0.80 meters and as much as 3.15 meters, she is built to be both voluminous and adaptable to tide-driven landscapes. KM finished the interior with sustainable bamboo for furniture and joinery, white-painted ceilings and overheads, and Treadmaster-covered cabin soles that the builder describes as durable, utilitarian, and low maintenance anchor. A third rudder mounted behind the propeller enhances maneuverability in narrow harbors, complementing the twin retracting rudders and giving the helmsman unusual authority in confined water.

Rig and Handling

The deck layout is arranged for short-handed ease, and every sail can be set from the cockpit anchor. A Hoyt Jib Boom lets the crew tack without effort and without losing speed, while a tall carbon sloop rig carries a sprit from which a Code 0 or asymmetrical chute can be flown. With 200 liters of side-to-side transferable water ballast, the 56 will sail flat and fast upwind anchor. The retracting keel and twin rudders let her safely cross oceans yet still visit estuaries and other shallow waters of just 80 centimeters, and drying out on her own bottom is a simple, safe activity that does not damage the appendages anchor.

Accommodations

The pilothouse and aft cockpit flow together to provide well-organized spaces for sailing in all weather and temperatures, and the pilothouse's large windows and overhead hatches deliver 360-degree sightlines and a clear view of the sails anchor. Below, the layout provides three double cabins and a pair of shower-equipped heads, while the saloon is roomy and the galley is arranged for convenience and safety in rough conditions. A workshop or systems cabin aft stows all spare parts and tools, and a practical method for stowing the dinghy keeps the deck uncluttered. An integrated step eases boarding from a low pontoon.

Refits and Ownership

Because the hull and deck are welded aluminum with thick insulation and utilitarian Treadmaster soles, the baseline structure asks little of an owner beyond normal systems upkeep. The bamboo joinery and white overheads are low-key and serviceable rather than precious. The retracting appendages and water-ballast system are the components most likely to reward a methodical owner familiar with hydraulic or mechanical lifting gear, but the boat was designed from the outset as a practical ocean cruiser with short-handed operation in mind.

The Verdict

The Stadtship 56 is a serious aluminum explorer that trades sparkle for genuine go-anywhere utility. Her lifting keel, twin rudders, and transferable water ballast make her as happy drying out in a tidal estuary as she is crossing an ocean, while the cockpit-driven sail plan and Hoyt Jib Boom keep short-handed passages sane. The pilothouse-forward layout and three-cabin plan suit a couple or family cruising hard, and the aft systems cabin is a rare concession to real-world self-sufficiency.

Pros

  • Welded aluminum hull and deck with watertight bulkheads and thick insulation
  • Lifting keel and twin rudders enable 80 cm shoal draft and safe drying out
  • All sails set from cockpit with Hoyt Jib Boom for effortless tacking
  • Pilothouse with 360-degree sightlines flows into aft cockpit
  • Aft workshop/systems cabin and practical dinghy stowage

Cons

  • 24-tonne displacement and explorer brief favor passage-making over agility
  • Retracting appendages and water ballast add systems to maintain
