Herreshoff 38 Cat Ketch Information, Review, Specs

Sailing Performance & Handling

The defining characteristic of the Herreshoff 38 is its unstayed, free-standing cat-ketch rig. By eliminating shrouds, stays, and the associated chainplates, the design significantly reduces windage and simplifies the sail plan. The boat typically utilizes wishbone booms, which allow the sails to maintain an aerodynamic shape across a wide range of wind angles. Because there is no headsail, tacking is an effortless affair; the helmsman simply steers through the wind without the need to winch in large overlapping genoas.

In terms of sea-kindliness, the 38 is known for its balanced "vane effect." By adjusting the relative trim between the large main and the nearly equal-sized mizzen, the boat can be made to steer itself on a reach or a run with minimal autopilot intervention. However, like many cat-ketches, the 38 lacks the upwind "pointing" ability of a traditional sloop. Without a headsail to provide a slot effect, the boat generally sails wider angles to the wind. The shallow draft (often less than 4 feet with the board up) makes it an exceptional coastal cruiser for regions like the Bahamas or the Chesapeake Bay, though it relies on its heavy centerboard for stability and lift when beating to weather.

Interior Comfort & Variations

Unlike the austere, narrow interiors of classic Herreshoff designs, the 38 Cat Ketch leverages its generous beam to provide a modern, "live-aboard" layout. The absence of a mast in the center of the main salon—owing to the masts being stepped far forward and aft—creates an unusually open and airy living space. Most hulls were configured with a traditional V-berth forward, followed by a spacious main salon with a folding centerline table.

The galley is typically located to starboard at the base of the companionway, featuring deep sinks and ample storage for extended voyaging. To port, a dedicated navigation station and a head with a shower are standard. Many owners highlight the joinery work, which often reflects the Bristol tradition of teak and holly soles paired with white bulkheads and mahogany or teak trim. While the hull remained consistent, some variations in the aft section exist; some boats were fitted with a large double quarter berth to port, while others utilized that space for increased storage or mechanical access.

Known Issues & Buyer’s Checklist

Prospective buyers should focus their inspection on the unique structural demands of an unstayed rig. Because the masts are not supported by wires, the "bury" (the portion of the mast below the deck) and the mast partners at the deck level bear immense leverage.

1. Mast Partners and Compression: Inspect the deck around the mast steps for crazing, delamination, or signs of movement. Any softness in the deck core here is a major structural concern.
2. Centerboard Assembly: The centerboard trunk and the pennant (the cable used to raise and lower the board) require regular maintenance. Buyers should verify the board moves freely and that the trunk is not weeping water into the bilge.
3. Wishbone Hardware: The specialized fittings at the mast and the "clew" of the wishbone booms are subject to high loads. Check for metal fatigue or hairline cracks in these custom castings.
4. Chainplate-Free Hull: While the lack of chainplates is a benefit, ensure that the hull-to-deck joint remains watertight, as older Nereus-built boats may experience "smile" cracks or leaks if the sealant has reached the end of its life.

Community & Resources

The primary hub for information on this model is the Herreshoff Marine Museum, which maintains the archives of the Herreshoff family and offers technical context for Halsey Herreshoff’s designs. While there is no longer a dedicated factory support system, the "Herreshoff Cat Ketch" community remains active on various cruising forums where owners exchange tips on rig tensioning and wishbone boom repairs.

The Verdict

The Herreshoff 38 Cat Ketch is an "intellectual" cruiser—a boat for the sailor who values simplicity and innovative engineering over conventional aesthetics. It is a robust, comfortable platform that excels in shallow-water gunkholing.

Pros:

• Ease of Handling: Single-handed sailing is made easy by the lack of headsails and shrouds.
• Draft Versatility: The centerboard design opens up cruising grounds inaccessible to deep-keeled sloops.
• Interior Volume: An open, mast-free salon provides the living space of a much larger vessel.

Cons:

• Upwind Performance: It will not point as high or sail as fast to windward as a stayed sloop.
• Rig Maintenance: Replacement parts for the unstayed masts or wishbone booms often require custom fabrication.
• Complexity of the Board: The centerboard adds a layer of mechanical complexity that requires periodic haul-outs.
