This solid-fiberglass monohull has a fin keel and spade rudder. Its CE Class A (Ocean) certification covers extended voyages where conditions may exceed wind force 8 and significant wave heights of 4 meters.
Design and Construction
Schöchl Yachtbau built the 42.1 in solid fiberglass. Roughly 8,378 pounds of iron ballast sits within a hull displacing 23,149 pounds. The boat measures 12.90 meters long with a beam of 3.98 meters. Her length-to-beam ratio of 3.17 makes her roomier than two-thirds of comparable sailboat designs.
Nissen’s lines produce a displacement-length ratio of 150. That places the 42.1 among the “light racers” and means 88 percent of similar designs are heavier. At the same time, the hull guarantees the typical weight stability that the builder cites as a hallmark of all Sunbeam yachts.
The capsize screening value is 1.83, low enough that the boat could be accepted for ocean racing by that formula alone. Her Motion Comfort Ratio of 28.2 sits more comfortably than 42 percent of similar boats. An immersion rate of about 333 kg/cm (1,866 lb/inch) completes the picture of a stiff, moderately light, ocean-capable cruiser.
Rig, Engine, and Handling
The fractional-sloop rig is intended for a small crew. The original review called the boat perfect for sailing with a minimal team.
Practical estimates for the running rigging are:
- Jib and genoa sheets: around 12.6 meters long and 14 mm in diameter
- Mainsheet: 31.5 meters long and 14 mm in diameter
- Spinnaker sheet: 27.7 meters long and 14 mm in diameter
Those dimensions suggest a straightforward, manageable sail plan rather than an over-canvased handful. Theoretical hull speed is 8.6 knots, providing a realistic upper bound under sail or power.
Auxiliary power comes from a 55-horsepower Volvo Penta D2-55 diesel with shaft drive. It provides the reserve needed to hold course in a seaway.
Cockpit and Accommodations
The center cockpit defines the 42.1. Raised above the deck, it creates a protected open-air salon that also serves as a private outdoor space. The layout was judged perfectly suited to fit in alongside seaside homes.
Below, the boat has 4+2 berths. That count supports two couples plus occasional guests without crowding the central-cockpit volume. The layout trades aft-quarter staterooms for the sheltered amidships cockpit, favoring living space and weather protection over a conventional aft-cockpit profile.
Cruising and Ownership
Fuel capacity is 110 gallons, while the water tanks hold 123 gallons. Together, those capacities suit extended cruising without constant replenishment. The Volvo Penta D2-55 is a common, well-supported diesel.
Prospective owners are looking at a 29-boat series with a clear production window and a single designer-builder pairing. The center-cockpit structure and solid laminate mean refit attention is more likely to focus on deck hardware and canvas than structural remediation.
The Verdict
The Sunbeam 42.1 is a coherent center-cockpit sport-luxury cruiser with genuine ocean credentials and a manageable rig for short-handed crews. Her light-racer displacement and low capsize screening value sit comfortably alongside the builder’s claimed weight stability. The center cockpit provides protected, private living space that sets her apart from the aft-cockpit norm.
Pros
- CE Class A (Ocean) certification for extended voyages in conditions beyond wind force 8 and significant wave heights of 4 meters
- Center cockpit creates a protected, private open-air salon
- Light-racer displacement alongside typical Sunbeam weight stability
- Small-crew-friendly rig with sensible sheet dimensions
Cons
- Only 29 built, resulting in a limited used-market pool
- Center-cockpit layout sacrifices conventional aft staterooms
