The Allmand 23, frequently designated as the HMS 23 (likely standing for the "Heritage Marine Series"), arrived during the late 1970s as Allmand Boats Inc. shifted its focus from purely power-driven vessels to a diverse fleet of cruisers. Built in Hialeah, Florida, the 23 was designed to be a "big" small boat, utilizing a high-volume hull and a relatively wide beam to offer accommodations usually reserved for 25- or 27-footers of that era. As a product of the Florida boat-building boom, it was constructed with a heavy hand on the fiberglass layup, prioritizing durability and structural rigidity over the lightweight agility found in contemporary racing dinghies. While the company's 31-foot sibling gained more national fame, the 23 served as an accessible entry point for coastal cruisers and families seeking a trailerable boat with true "weekending" capabilities.

Sailing Performance & Handling

The Allmand 23 is characterized by its stability and predictable motion rather than raw speed. With a displacement that leans toward the heavier side for a 23-foot trailerable sailboat, it possesses a high degree of momentum once moving. The boat typically features a shoal draft keel, which was a deliberate design choice by Tom Allmand to suit the thin waters of the Florida Keys and the Bahamas. This design allows for excellent gunkholing capabilities but results in some compromise when sailing close-hauled; the boat tends to exhibit more leeway than a deep-keeled racer and is not known for its ability to point exceptionally high into the wind.

In terms of handling, the Allmand 23 is remarkably forgiving for novice sailors. Its wide beam provides a significant righting moment, making the boat feel "stiff" and resistant to excessive heeling in moderate gusts. Anecdotal reports from long-term owners suggest that the boat tracks well due to its balanced sail plan, though the helm can become heavy if the boat is over-canvased in high winds. It is a vessel designed for the "middle of the road"—sturdy enough to handle a choppy bay but light enough to be managed by a small crew or a single-handed sailor.

Interior Comfort & Variations

The interior of the Allmand 23 is where the builder's powerboat heritage is most evident. By pushing the beam out and maintaining relatively high freeboard, Allmand created a cabin that feels cavernous for a boat under 25 feet. The layout typically features a standard V-berth forward, a compact settee arrangement that can often be converted into additional sleeping berths, and a modest galley area.

A hallmark of the Allmand 23 is the surprising amount of headroom, which was a major selling point in original marketing materials. While most boats in this size class require a "pop-top" to achieve standing room, the Allmand 23 provides a more integrated, permanent cabin feel. The use of teak accents and molded fiberglass liners was standard, reflecting the company's commitment to quality interiors that were easy to clean yet felt traditional. Sibling models, such as the Allmand 25, utilized a very similar design philosophy but offered a slightly expanded cockpit and an enclosed head, whereas the 23 often utilized a more simplified porta-potti or compact head arrangement to maximize living space.

Known Issues & Buyer’s Checklist

Prospective buyers of an Allmand 23 should focus on the specific aging characteristics of 1970s and 80s Florida-built fiberglass. While the hulls are generally considered "overbuilt," they are not immune to the passage of time.

  • Deck Delamination: Like many boats of this era, the Allmand 23 uses a cored deck (often balsa or plywood). Inspection should focus on soft spots around the mast step and chainplates, where water intrusion can rot the core over decades.
  • Chainplate Anchors: The chainplates on the 23 are known to develop leaks if the sealant is not maintained. Because these are often anchored to structural bulkheads, any long-term leaking can lead to "bulkhead rot," a significant structural repair.
  • Osmotic Blistering: While Allmand used quality resins, some hulls from the early 80s have shown a tendency toward gelcoat blisters. A haul-out inspection is essential to check the integrity of the bottom.
  • Rudder Bearings and Bushings: Given the age of these vessels, the rudder assembly often develops play. Buyers should check for "wobble" in the tiller head and inspect the pintles and gudgeons for wear or stress cracks.

Community & Resources

While there is no longer a formal factory-backed association, the Allmand community remains active through various "Allmand Sailors" groups and regional cruising clubs. Technical data is often shared through informal networks of owners who prize the boat’s "built-like-a-tank" reputation. Detailed historical context regarding the builder's transition from power to sail can be found through maritime archives focusing on the Hialeah marine industry.

The Verdict

The Allmand 23 is a robust, high-volume pocket cruiser that prioritizes comfort and stability over racing performance. It is an ideal choice for coastal sailors who value interior space and a shallow draft.

Pros:

  • Exceptional interior volume and headroom for its length.
  • Sturdy fiberglass construction that handles chop better than lighter competitors.
  • Shoal draft is perfect for coastal exploring and easy trailering.
  • Simple, easy-to-manage sail plan for solo or family sailing.

Cons:

  • Mediocre upwind performance and significant leeway in light air.
  • Heavier than many modern 23-footers, requiring a substantial towing vehicle.
  • Common age-related issues with deck cores and bulkhead moisture.
  • Lack of modern "sugar scoop" transoms makes water access more difficult.
