The Tripp Invicta holds a hallowed position in maritime history as the vessel that effectively silenced skeptics of fiberglass construction on the high seas. Designed by the legendary William H. Tripp Jr. and produced by Pearson Yachts beginning in 1960, this 37-foot, 8-inch centerboard yawl was engineered for the rigorous Midget Ocean Racing Club (MORC) and CCA (Cruising Club of America) rules of the era. Its defining moment arrived in 1964 when the Invicta Burgoo became the first fiberglass yacht to secure an overall win in the prestigious Newport-to-Bermuda Race, proving that "glass" boats possessed the structural integrity and speed to outpace traditional wooden competitors. With its graceful overhangs, narrow beam, and versatile centerboard configuration, the Invicta remains a quintessential example of the "classic plastic" era.

Sailing Performance & Handling
The Invicta’s performance is defined by its deep-V hull and centerboard design, which allows for a versatile draft ranging from approximately 4 feet, 6 inches with the board up to nearly 8 feet when fully deployed. This configuration makes the Invicta a formidable coastal cruiser capable of "gunkholing" in shallow waters, while still maintaining the tracking and stability required for offshore passages. Because it was designed during the CCA era, the boat features a high displacement-to-length ratio, resulting in a motion that is predictable and "kind" in a seaway.
Owners often describe the Invicta as a balanced sailor, particularly in the yawl configuration, where the mizzen sail can be used to fine-tune the helm or provide steadying power while at anchor. According to historical retrospectives from Sail Magazine, the boat was noted for its ability to carry sail late into a blow, though like many narrow-beamed designs of its time, it can be "wet" in a chop, with the low freeboard allowing spray to find the cockpit. The boat tracks exceptionally well downwind, a hallmark of Tripp’s designs which often featured a slightly more modern underbody than the full-keel Alberg designs of the same era.
Interior Comfort & Variations
The interior of the Invicta reflects the pragmatic approach of the early 1960s, prioritizing seaworthiness over the expansive volume found in modern yachts. The cabin is typically laid out with a traditional V-berth forward, followed by a head and hanging locker. The main salon features settee berths and a fold-down table, providing sleeping accommodations for up to six.
Pearson produced two distinct versions of the boat: the Invicta I and the Invicta II. The Invicta II, introduced later in the production run, featured a redesigned "raised" cabin trunk that significantly improved standing headroom and increased the feeling of interior volume without compromising the yacht's sleek profile. While the Invicta I is often favored for its lower, more classic silhouette, the Invicta II is the preferred choice for long-term cruising due to the added vertical space. Teak and mahogany joinery were standard throughout both versions, creating a warm, traditional atmosphere that has aged well in well-maintained examples.
Popular Mentions & Media
The Invicta’s fame is inextricably linked to the yacht Burgoo. Commanded by Milton "Bus" Ernstmeyer, Burgoo’s 1964 victory in the Newport-to-Bermuda Race is frequently cited in sailing literature as a turning point for the industry. This victory is documented in the historical archives of the Mystic Seaport Museum, which houses many of the original William Tripp Jr. design records. The boat's triumph was a catalyst for the mass adoption of fiberglass by serious offshore racers who had previously viewed the material as experimental.
Known Issues & Buyer’s Checklist
Synthesizing decades of owner reports and forum discussions from the Pearson community, buyers should focus on these high-signal technical areas:
- Centerboard Trunk: The trunk and the board's lifting mechanism (cables, sheaves, and the pennant) are critical points of failure. Corrosion or marine growth inside the trunk can jam the board, and the pivot pin should be inspected for wear.
- Deck Core: Pearson used balsa-coring in the decks. Over six decades, portlights, stanchions, and cleats may have leaked, leading to localized delamination or "soft spots." A moisture meter and percussion testing are essential during a survey.
- Chainplates and Rigging: The original stainless steel chainplates are often nearing the end of their fatigue life if not previously replaced. Given the boat's age, a thorough inspection of the attachment points to the hull is mandatory to prevent rig failure.
- Atomic 4 Engine: Many Invictas were originally fitted with the Universal Atomic 4 gasoline engine. While these are remarkably durable, many modern buyers prefer diesel conversions for safety and fuel efficiency on long passages.
- Rudder Hardware: The bronze hardware on the rudder and pintles should be checked for "pink" coloration, a sign of electrolysis and structural weakening that can occur if the boat’s bonding system has failed.
Community & Resources
Owners typically find technical support through the Pearson Yachts Portal and the wider William Tripp Jr. design community. While a dedicated "Invicta-only" association is smaller than those for the Pearson Ensign or Triton, the Pearson Yacht Owners Association provides a wealth of shared knowledge regarding restoration, parts sourcing, and original manufacturer specifications.
The Verdict
The Tripp Invicta is a "sailor’s sailboat," offering a blend of historical significance and robust offshore capability. It is best suited for those who value traditional aesthetics and a proven racing pedigree over modern interior volume.
Pros:
- Historic racing pedigree as a Bermuda Race winner.
- Shallow draft versatility with the centerboard configuration.
- Graceful, timeless lines that stand out in any harbor.
- Heavy-weather stability and a comfortable motion at sea.
Cons:
- Limited interior headroom, especially in the Invicta I variant.
- Relatively "wet" ride in heavy chop due to low freeboard.
- High maintenance requirements typical of 60-year-old fiberglass hulls and systems.
