US 41 Information, Review, Specs

This model is part of a distinct lineage of Charles Angel designs. It is the direct evolution of the Triangle 40 and shares significant DNA with the US 46, which was effectively an elongated version of the same hull form. According to archival data from the Grampian Owners Marina, the US 41 was designed to maximize liveaboard volume while maintaining the safety of a deep, protected cockpit. It remains a fixture in the Great Lakes and the Caribbean, often sought after by cruisers who prioritize structural integrity over modern planing speeds.

Sailing Performance & Handling

The US 41 is a traditional heavy-displacement cruiser, typically weighing in at approximately 22,000 pounds with a ballast-to-displacement ratio near 36%. This mass, combined with a full-keel or long-fin keel configuration (depending on the specific production year and draft option), results in a boat that is exceptionally stable and "kind" in a seaway. It does not slam into head seas; rather, it uses its momentum to punch through them, providing a dry and predictable ride.

With a Displacement to Length (D/L) ratio well into the "heavy cruiser" category, the US 41 requires a stiff breeze to truly wake up. In light airs, the significant wetted surface area can make the boat feel sluggish. However, the ketch rig—the most common configuration for this model—allows for a versatile sail plan. Owners frequently report that the "jib and jigger" (headsail and mizzen) combination allows the boat to remain balanced and under control in 25-plus knots of wind, where a sloop would be struggling with reefing. The tracking is excellent, and once the sails are trimmed, the US 41 is known to hold its course with minimal helm correction, making it an ideal candidate for older mechanical windvane steering systems.

Interior Comfort & Variations

The interior of the US 41 was a primary selling point during its production run, offering a level of privacy that few 40-footers of the era could match. The center-cockpit design allows for a completely private "great cabin" aft, accessible via a walkthrough gallery or, in some earlier configurations, a separate companionway. This aft cabin typically features two large berths and a private head, making it a true master suite.

The main salon is characterized by its generous beam of 12 feet and a traditional teak-heavy aesthetic. Grampian’s craftsmanship is evident in the solid wood trim and cabinetry, which lacks the "liner-heavy" plastic feel of modern production boats. The galley is generally located in the walkthrough to the aft cabin, providing a secure place to cook while underway, braced against the engine box or the hull side. Variations in the model often focused on the forward V-berth and storage options, with some hulls featuring a second dedicated shower stall. Headroom is a notable strength, exceeding 6’4” in most areas of the main cabin, a feature Alex McGruer and the Grampian team prioritized across their larger hulls.

Known Issues & Buyer’s Checklist

Prospective buyers should focus on the following high-signal areas common to Grampian-built US Yachts of this vintage:

• Deck Core Integrity: Like many boats of the 1970s, the US 41 utilizes a balsa-cored deck. Soft spots around the chainplates, stanchion bases, and the mizzen mast step are common if the hardware has not been re-bedded every decade.
• Chainplate Inspection: The chainplates on the US 41 are heavy-duty but can suffer from crevice corrosion where they pass through the deck. Because they are often glassed into the bulkheads, inspection requires careful removal of interior trim.
• Osmotic Blistering: While the hull is thick, early 1970s resins were prone to blistering. A haul-out and moisture meter test are essential to determine if the hull has been epoxied or if a bottom peel is necessary.
• Fuel and Water Tanks: The original iron or aluminum tanks may be reaching the end of their service life. Access can be difficult, as many were installed before the deck was joined to the hull.
• Engine Access: While the engine is centrally located under the cockpit, the "walkthrough" configuration can sometimes make accessing the rear of the engine or the transmission a challenge for larger mechanics.

Community & Resources

The primary hub for technical support is the Grampian Owners Marina, which maintains a repository of brochures, rigging diagrams, and manual scans specifically for the US Yachts line built in the Canadian plant. There is also a robust presence of owners on general cruising forums who share specific "refit" threads for the US 41, focusing on upgrading the electrical systems to modern standards.

The Verdict

The US 41 is a "tank" of a sailboat, built for a time when the goal was to survive a storm rather than outrun it. While it lacks the agility of a modern fin-keel racer, its massive interior and sea-kindly motion make it an outstanding value for long-term liveaboards or coastal cruisers on a budget.

Pros:

• Exceptional interior volume with a true private master aft cabin.
• Heavy-duty fiberglass construction that can withstand significant abuse.
• Ketch rig provides excellent balance and sail-handling options in heavy weather.
• Stands up to its sails well with a very comfortable, stable motion.

Cons:

• Poor light-wind performance due to high displacement and wetted surface.
• Potential for costly deck core repairs if maintenance was neglected.
• Slow maneuvers in tight marinas due to the long keel and prop walk.
