Design Brief & Intent
The Sundance 13 was designed primarily as a sporty lake and near-shore dayboat, optimized for flat water and moderate breezes. It was built for sailors who wanted more performance and a greater technical challenge than contemporary mass-market dinghies could provide. What set the Sundance 13 apart from its competitors—and from its larger siblings in the El-Mar line—was its uncompromising focus on sailing dynamics within a highly compact footprint. The interior is a minimalist, open-cockpit configuration constructed entirely of molded fiberglass, prioritizing low maintenance and easy wash-down over luxury. Seating is integrated directly into the side tanks, which double as buoyant safety chambers, emphasizing the boat's utilitarian, day-sailing purpose.
Sailing Performance & Handling
Under sail, the Sundance 13 is a remarkably lively and responsive performer, owing to its exceptionally light displacement of just 205 pounds. Its sail area-to-displacement ratio of 43.72 places it firmly in the category of high-performance dinghies, indicating a boat that is quick to accelerate and will plane easily in a moderate breeze. However, this massive ratio also demands active mainsheet management and athletic hiking from the crew to prevent capsizing.
The capsize screening ratio of 3.39—while a metric of concern for a ballasted keelboat—simply highlights that the Sundance 13 is a tender, ultra-lightweight centerboarder. Capsizing is a natural consequence of over-canvasing in a blow, though the molded fiberglass hull features built-in flotation to ensure the boat remains buoyant and straightforward to right. With its pivoting centerboard fully extended, the draft reaches 3.5 feet, allowing the boat to point remarkably high into the wind. Retracting the board reduces the draft to its minimum of just 5 inches, making it easy to beach, launch from a dolly, or navigate thin inland waters.
Market Snapshot & Economics
Because the El-Mar Boat Company ceased operations in the late 1970s, the Sundance 13 is a rare find on the contemporary brokerage market. Rather than commanding a financial premium, it trades at nominal values typical of vintage fiberglass dinghies, usually shifting hands through local classifieds, regional sailing clubs, or enthusiast forums. For those who locate a well-preserved hull, the refit economics are highly favorable because of the lack of an engine, electrical systems, or complex plumbing. However, prospective buyers must weigh the low initial purchase price against the reality of sourcing replacement parts. Because first-party spares have not existed for decades, any major restoration involving the mast, boom, or rudder will require adapting hardware from more common contemporary dinghies or commissioning custom fabrication.
Known Issues & Triage
The primary structural concern for a vintage Sundance 13 is fiberglass fatigue and core degradation. While the hull is a solid fiberglass layup, structural reinforcement points—such as the transom, centerboard trunk, and mast step—often relied on plywood backing plates that are highly susceptible to rot after decades of exposure to moisture. Buyers should closely inspect the mast step for cracking or compression, as the downward force of the fractional rig can deform a weakened deck.
The pivoting centerboard assembly is another critical area to examine. The pivot bolt and trunk can wear over time, leading to leaks or a jammed board. Triage typically involves removing the centerboard to inspect the hinge, replacing worn gaskets, and sealing any hairline fractures around the trunk with marine-grade epoxy. Additionally, the cockpit floor and integrated flotation chambers must be checked for soft spots and air tightness, as water intrusion into these sealed cavities compromises the structural integrity and the reserve buoyancy of the boat.
The Verdict
The Sundance 13 is a charming, historically significant slice of 1970s American dinghy sailing. It successfully bridges the gap between simple beach toys and technical racing sloops, providing a highly responsive platform for those who love active, hands-on helming. While its scarcity and lack of factory support make it a project of passion rather than convenience, it rewards its owners with pure sailing feedback and a distinct presence on the water.
Pros:
- Highly responsive helm with impressive planing potential in moderate winds.
- Sophisticated fractional sloop rig teaches true multi-sail handling.
- Extremely lightweight hull is easy to trailer, dolly-launch, or garage-store.
- Shallow minimum draft allows for easy beaching and sailing in thin water.
Cons:
- Manufacturer has been out of business for decades, making original replacement parts non-existent.
- Tender, high-performance nature requires constant crew weight management to prevent capsizing.
- Structural backing plates in the transom and mast step are prone to moisture rot and require careful inspection.
- Limited cockpit space and low freeboard restrict comfort in choppy, cold-water environments.
