The Maine Cat 30 is a seminal design in the world of midsized multihulls, representing founder Dick Vermeulen’s radical departure from the cramped, "cavelike" interiors often associated with 30foot catamarans. Produced in Bremen, Maine, starting in the mid1990s, the model became a cult favorite for its signature open bridge deck layout. Unlike traditional catamarans that divide the cockpit from the saloon with a heavy bulkhead, the Maine Cat 30 features a unified, protected living space at deck level, sheltered by a hardtop and flexible enclosure. This "great room" concept allows for 360degree visibility and exceptional ventilation, making the vessel feel significantly larger than its 30foot length suggests.

The construction of the Maine Cat 30 utilized high-tech materials long before they were standard in the industry. The hulls were built using a thermoformed Corecell foam core with vinylester resin, a method detailed by the manufacturer to ensure a high strength-to-weight ratio. This lightweight approach, combined with a slim hull form and retractable daggerboards, positioned the Maine Cat 30 as a genuine performance cruiser capable of out-pointing and out-pacing many larger, fixed-keel production catamarans.

Sailing Performance & Handling

The Maine Cat 30 is frequently characterized by its "sports car" feel compared to the "minivan" handling of more voluminous cruisers. With a displacement of approximately 6,500 to 7,000 pounds, the boat is exceptionally light. This low mass, paired with a generous sail plan, results in a high sail area-to-displacement (SA/Disp) ratio that allows the boat to accelerate in light airs where heavier boats might require motoring.

A defining performance feature is the use of dual daggerboards. According to an editorial review in Cruising World, these boards allow the boat to point much higher than catamarans equipped with shallow mini-keels. When the boards are raised, the boat draws only 18 inches, allowing it to navigate shallow tidal flats or beach itself for maintenance. Owners often report that the boat tracks exceptionally well and maintains a high degree of "sea-kindliness," a trait attributed to its balanced hull volumes and the lack of a heavy forward crossbeam, which reduces hobby-horsing in choppy conditions.

Interior Comfort & Variations

While the bridge deck serves as the primary social hub, the Maine Cat 30 utilizes the volume within its two hulls for essential accommodations. The "open design" means that instead of a central saloon below, the living quarters are split. Typically, the port hull houses a longitudinal galley and a double berth aft, while the starboard hull contains a head with a shower and an additional double berth.

The interior is noted for its functional simplicity and easy-to-clean surfaces, reflecting the builder's philosophy of low-maintenance cruising. Variations over the production run were minimal, though later hulls often featured refined cabinetry and lighting. The bridge deck itself acts as the primary "living room," featuring a large dinette that can often be converted into an additional sleeping area. Because the bridge deck is not fully enclosed by a structural bulkhead, the transition between the hulls and the deck feels more integrated than in traditional designs. The use of a high-quality Strataglass or Stamoid enclosure allows the bridge deck to remain comfortable in inclement weather while maintaining the "porch-like" atmosphere that owners prize.

Known Issues & Buyer’s Checklist

Prospective buyers should focus on several specific technical areas unique to the Maine Cat's design and age.

  • Enclosure Condition: Because the bridge deck living space relies on a soft enclosure rather than a hard bulkhead, the condition of the zippers, clear panels (Strataglass), and canvas is critical. Replacing a full enclosure is a significant expense and essential for the boat's "all-weather" utility.
  • Daggerboard Trunks: Inspect the daggerboard trunks for impact damage or stress cracks. Ensure the boards move freely in their tracks; over time, marine growth or warping can cause binding.
  • Outboard Maintenance: Most Maine Cat 30s are powered by twin 9.9hp or 15hp high-thrust outboard engines mounted in wells. These require careful inspection of the lifting mechanisms and the seals around the engine wells to prevent water ingress or exhaust fumes from entering the bridge deck.
  • Core Integrity: While the thermoformed Corecell core is highly resistant to rot, any aftermarket through-hull fittings or deck hardware additions should be checked for proper sealing to ensure moisture hasn't compromised the laminate.
  • Standing Rigging: Many units are now reaching an age where the original standing rigging may be nearing the end of its reliable lifespan. Particular attention should be paid to the mast base and the chainplates.

Community & Resources

The Maine Cat community is tight-knit, supported by the manufacturer’s continued operation in Maine. The most prominent resource for technical support and owner collaboration is the Maine Cat Official Website, which maintains archives of original specifications and design goals. Owners also frequently congregate on multihull-specific forums to exchange data on outboard engine upgrades and sail plan optimizations.

The Verdict

Pros:

  • Superior performance and upwind pointing ability due to daggerboards and light weight.
  • Unrivaled 360-degree visibility and ventilation from the "open design" bridge deck.
  • Extremely shallow draft (18 inches with boards up) for versatile coastal cruising.
  • High-quality Maine-built construction using advanced core materials.

Cons:

  • Accommodations are split between hulls, which may feel disconnected for some families.
  • Reliance on a soft enclosure for the main living area requires more maintenance than a hard-bulkhead saloon.
  • Limited payload capacity compared to wider, heavier production cruising catamarans.
