The Dyer Delta 19 is a rare and specialized chapter in the history of The Anchorage, Inc., the Rhode Island builder better known for the ubiquitous Dyer Dhow and the rugged Dyer 29 powerboat. Produced in extremely limited numbers—reportedly only 12 units were built between 1966 and 1968—the Delta 19 was an ambitious attempt to offer a high-performance sailing dinghy that leveraged the company’s expertise in fiberglass construction. Designed by naval architect Charles F. Street, the vessel was intended to provide a spirited sailing experience that contrasted with the more utilitarian tenders in the Dyer catalog. According to historical records at Soundings Online, the production of the Delta 19 was cut short not due to design failure, but because of a strategic shift within The Anchorage to meet the surging demand for their fiberglass powerboats during the late 1960s.

Sailing Performance & Handling
The Delta 19 is characterized by an exceptionally high sail-area-to-displacement (SA/Disp) ratio, estimated near 45.0 based on its 189-square-foot sail plan and a featherlight 550-pound displacement. This ratio places the boat firmly in the realm of high-performance dinghies rather than traditional day-sailers. Owners and historical data suggest the boat is highly responsive and capable of planing in moderate breezes, a trait enhanced by its fractional sloop rig and deep 4.5-foot maximum draft when the centerboard is fully extended.
The centerboard design allows for a versatile sailing profile, reducing to a mere 0.75-foot draft for beaching or shallow-water navigation. However, the light displacement means the boat relies heavily on crew weight for stability. While the fractional rig provides superior control over sail shape compared to a masthead configuration, the Delta 19 requires an attentive hand on the tiller. In light winds, the boat is remarkably agile, but as the breeze freshens, the significant sail area necessitates early reefing or an athletic crew to maintain an upright posture.
Popular Mentions & Media
Because of its extremely limited production run of only 12 hulls, the Delta 19 occupies a "ghost ship" status in nautical literature. It is occasionally mentioned in vintage promotional materials from The Anchorage, Inc. alongside its siblings, the Dyer Dhow and the Dyer Dink. Its most significant cultural footprint is its inclusion in the specialized archives of the Mystic Seaport Museum, which preserves much of the history of Bill Dyer’s contributions to American fiberglass boatbuilding.
Known Issues & Buyer’s Checklist
Prospective buyers of a Delta 19 are dealing with a vintage fiberglass vessel over 50 years old. Due to its rarity, certain model-specific parts are impossible to source off-the-shelf.
- Centerboard Trunk Integrity: Like many centerboarders of this era, the trunk is a high-stress area. Inspect the fiberglass joint where the trunk meets the hull for stress cracks or signs of leaking, which can indicate structural fatigue from years of lateral pressure.
- Hardware Backing: Early fiberglass boats often lacked sufficient backing plates for high-load hardware. Check the chainplates and the forestay attachment point for "spiderweb" crazing in the gelcoat, which suggests the laminate is flexing under the tension of the fractional rig.
- Rudder Assembly: The rudder and its pintles are subject to significant torque given the boat's potential speed. Ensure the transom is rigid and that the rudder head shows no signs of splitting or delamination if it is the original wooden or early composite component.
- Spars and Rigging: The Delta 19’s mast and boom were lightweight for their time. Inspect for any corrosion at the spreaders or corrosion around stainless-steel fittings riveted into the aluminum.
Community & Resources
There is no dedicated owner association for the Delta 19 due to its scarcity. However, owners generally find support through the broader Dyer community and general maritime heritage groups.

- Downeast Boat Forum: While primarily focused on powerboats, this community frequently discusses the construction techniques and history of The Anchorage, Inc.
The Verdict
The Dyer Delta 19 is a collector's piece—a high-performance relic from a period of intense innovation in American boatbuilding. It is best suited for a sailor who appreciates the pedigree of The Anchorage and seeks a lively, responsive platform for protected-water racing or spirited afternoon runs.
Pros
- Historic Pedigree: Built by one of the pioneers of fiberglass construction.
- High Performance: Planes easily and offers an athletic sailing experience.
- Shallow Draft: Centerboard design allows for easy trailering and beaching.
Cons
- Extremely Rare: With only 12 built, finding one for sale—or finding replacement parts—is a significant challenge.
- Demanding Handling: Not a "set it and forget it" daysailer; requires active crew work in heavy air.
- Minimal Utility: Lacks any significant storage or interior amenities, focusing purely on sailing mechanics.
