The Marsh Hen is a 17-foot sharpie-inspired micro-cruiser designed by Rueben Marsh and produced by Marsh Marine. Specifically engineered for the shallow "gunkholes" of the Florida coastline, this vessel represents a specialized niche in the small-boat world: the fiberglass sharpie. With a draft that allows it to navigate in as little as six inches of water with the centerboard retracted, the Marsh Hen has earned a dedicated following among coastal explorers and participants in minimalist endurance events like the Everglades Challenge. The design prioritizes ease of trailering, quick rigging, and the ability to find refuge in waters inaccessible to traditional keelboats.

Sailing Performance & Handling

The Marsh Hen utilizes a flat-bottomed hull form typical of the American sharpie tradition, which provides significant initial stability. This hull shape, combined with its 6' 2" beam, creates a platform that feels remarkably solid underfoot for a 17-foot boat. However, as with most flat-bottomed designs, the ride can become "slappy" in a choppy head sea, as the hull hits the waves rather than slicing through them.

The most common configuration for the Marsh Hen is a cat-ketch rig featuring two unstayed masts. This setup is highly regarded for its simplicity and safety; without shrouds or stays, the masts can be stepped in minutes, and the sail plan is easily balanced. By adjusting the relative trim of the main and mizzen, a sailor can achieve "self-steering" capabilities on many points of sail. The unstayed spars also act as a safety valve, spilling wind in sudden gusts by flexing. While it is not a high-performance windward machine—lacking the deep bite of a weighted keel—the Marsh Hen tracks well off the wind and offers a forgiving experience for solo sailors. Technical discussions often highlight its low displacement-to-length ratio, which allows the boat to move easily in light airs, though it relies heavily on its centerboard for upwind progress.

Interior Comfort & Variations

Despite its modest 17-foot length, the Marsh Hen is designed as a pocket cruiser rather than an open daysailer. It features a small cuddy cabin that provides an enclosed living space, though "comfort" is a relative term in this size bracket. The interior is primarily occupied by a V-berth that can accommodate two adults for overnight "camp-cruising." Headroom is restricted to a sitting position, which is standard for the micro-cruiser class.

Marsh Marine offered variations in the layout and rig over the production run. While the cat-ketch rig is the hallmark of the model, some versions were produced with a sloop rig for sailors preferring a more conventional setup with a jib. The interior remains minimalist, usually finished in a simple gelcoat with wood trim, emphasizing utility and ease of wash-down after a weekend of salty coastal use. A sibling model often mentioned in the same breath is the Sandpiper, a smaller version approximately 15 feet in length, which shares the same sharpie DNA but offers significantly less interior volume.

Known Issues & Buyer’s Checklist

Prospective buyers of a Marsh Hen should focus their inspections on the unique structural requirements of a shallow-draft sharpie.

  • Centerboard Trunk: The centerboard trunk is a high-stress area. Inspect the trunk for leaks where it joins the hull and check the pivot pin for wear. If the board has been slammed into shoals repeatedly, the trunk may show stress cracks.
  • Mast Steps: Because the masts are unstayed, the mast steps and partners bear the full load of the sail plan. Look for crazing or structural deformation in the deck and the hull floors where the masts are seated.
  • Core Integrity: Like many fiberglass boats of its era, the Marsh Hen may use a sandwich core in the deck or cabin top. Check for "soft spots" or delamination, which indicates water intrusion into the core material.
  • Rudder Assembly: The kick-up rudder is essential for the boat’s shallow-water mission. Ensure the pivot mechanism is smooth and that the gudgeons and pintles are securely fastened to the transom without excessive play.

The Verdict

The Marsh Hen is a purpose-built tool for the sailor who values access to the shoreline over blue-water capability. It is a quintessential "Florida boat" that excels in the keys and marshes where other boats would find themselves high and dry.

Pros

  • Extreme Shallow Draft: Navigates where most sailboats cannot follow.
  • Simple Rigging: The unstayed cat-ketch rig is exceptionally easy to manage and reef.
  • Trailability: Light weight and a flat bottom make launching and retrieving a one-person job.
  • Stability: High initial stability makes it a comfortable platform for its size.

Cons

  • Limited Headroom: The cabin is strictly for sleeping or seeking shelter, not for extended "living."
  • Upwind Limitations: The sharpie hull and centerboard configuration lack the windward efficiency of a round-bilge or keel boat.
  • Rough Water Motion: The flat bottom provides a jarring ride in significant chop.
