Discovery 50 Catamaran Information, Review, Specs

Sailing Performance & Handling

The Discovery 50 Catamaran is fundamentally a heavy-displacement cruiser, eschewing the lightweight, high-performance ethos of brands like Outremer or Gunboat in favor of sea-kindliness and load-carrying capacity. With a displacement of approximately 14,500 kg, the hull is designed to provide a stable platform in a seaway. According to editorial analysis from Yachting World, the boat excels in a "power-cruising" mode, utilizing a tall fractional rig and a self-tacking jib that allows for effortless tacking from the safety of the cockpit.

Handling is characterized by its "one-touch" sailing philosophy. All primary lines are led to electric winches at the helm station, which is uniquely positioned to offer protection from the elements while maintaining visibility over the coachroof. Because it utilizes fixed keels rather than daggerboards, the Discovery 50 tracks exceptionally well on a reach and offers a forgiving motion in offshore conditions. While its light-wind performance is understandably dampened by its weight, once the breeze exceeds 12–15 knots, the hull settles into a consistent, powerful gait. The inclusion of a large reaching sail on a furler is often cited as a necessity for maintaining passage speeds in the trades.

Interior Comfort & Variations

The interior of the Discovery 50 Catamaran is its most distinctive feature, defined by a level of joinery and finish rarely seen in multihulls. The raised saloon is a hallmark of the Discovery brand, providing 360-degree visibility whether seated or standing. A notable variation in this model is the inclusion of an internal navigation and steering station, allowing the crew to monitor systems and steer via autopilot in inclement weather while remaining inside the climate-controlled cabin.

Living quarters are typically configured in an "Owner’s Version" layout. This dedicates the entire starboard hull to the owner, featuring a large double berth aft, a dedicated office or dressing area amidships, and a massive head compartment forward. The port hull generally houses two guest cabins, each with en-suite facilities. As detailed in reviews by Cruising World, the use of vertical coachroof windows significantly reduces solar heat gain in the tropics compared to the slanted windows found on contemporary French catamarans. Variation in the model line was minimal, though some later hulls—sometimes referred to as the "Discovery 50 Ocean"—saw minor refinements in the galley layout and the integration of more advanced lithium-ion battery banks to support the "gas-free" living options preferred by some owners.

Popular Mentions & Media

The Discovery 50 Catamaran gained significant critical acclaim upon its debut, earning the "Best Multihull Cruiser" title in the 2011 Cruising World Boat of the Year awards. Its cultural footprint is most visible within the World Cruising Club (WCC) circles, as several units have participated in the Atlantic Rally for Cruisers (ARC), frequently being highlighted for their luxury-first approach to crossing oceans. The model's development was also a point of interest for technical journalists, as it represented one of the first times a high-end British monohull builder successfully transitioned their brand identity into the catamaran market.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Discovery 50 with a focus on its complex mechanical and electrical systems, which are significantly more involved than those on a standard production cat.

• Fixed Keel Integrity: Because the keels are integral to the hull for tracking and grounding protection, a thorough survey should inspect the keel-to-hull joints for stress crazing, particularly if the boat has been navigated in thin waters like the Bahamas.
• Charging and Power Management: These boats were often fitted with heavy-load appliances (electric ovens, dive compressors, air conditioning). Inspect the age and health of the house bank and the integration of the Mastervolt or Victron charging systems, as older units may require firmware or hardware upgrades to handle modern lithium conversions.
• Window Seals: The large, vertical salon windows provide excellent views but are subject to significant UV stress and thermal expansion. Check for signs of leaking or "creeping" sealant around the perimeters.
• Saildrive Maintenance: The twin Yanmar engines utilize saildrives. It is essential to verify the replacement history of the rubber diaphragm seals and check for any signs of corrosion on the aluminum casings, which can be accelerated by shore power leakage.

Community & Resources

Owners of the Discovery 50 Catamaran are supported by a tight-knit community of Discovery owners. While the shipyard has undergone ownership changes, the technical legacy is preserved through the Discovery Yacht Owners Forum, a private association where owners share maintenance logs and technical modifications. Technical support often continues through the original designers at Dixon Yacht Design, who maintain the archives for the hull and rig specifications.

The Verdict

The Discovery 50 Catamaran is a niche vessel designed for the sailor who wants the space of a multihull without the "plastic" feel of high-volume production boats. It is a robust, luxurious, and heavy-duty voyager that sacrifices raw speed for total comfort.

Pros:

• Exquisite British joinery and high-end interior finish.
• Exceptional 360-degree visibility from a protected internal helm station.
• True short-handed sailing capability with electric winches and self-tacking jib.
• High displacement provides a much smoother motion in heavy seas than lighter cats.

Cons:

• Heavy weight limits performance in light air (under 10 knots of wind).
• Complex onboard systems require a high degree of maintenance.
• Higher price point and maintenance costs compared to production-grade catamarans.
