Design Brief & Intent
The primary mission of the Wave Rider Catamaran was to serve as a fast, lightweight, and easily managed day-sailer capable of beach launching and high-speed reach sailing. Designed for recreational sailors who wanted the thrill of multihull speed without the mechanical complexity of daggerboards or centerboards, the boat utilized asymmetric hulls. This design allowed the hulls themselves to generate lateral resistance and minimize leeway, similar to the concept later popularized by other classic beach cats.
By eliminating daggerboards, Waverider Corp created a highly practical beach-landing vessel with a draft of only one foot. It could be sailed directly onto sandy shores without risking structural damage to foil trunks. In terms of construction, the boat was ahead of its time, utilizing a fiberglass layup over a structural plywood core to achieve a displacement of just 360 pounds. This kept the platform rigid enough to handle the torsional stresses of a catamaran rig while remaining light enough for two people to manually handle on a trailer or beach dolly. Its eight-foot beam provided a wide, stable platform, presenting a direct alternative to the emerging class of high-performance monohull dinghies and early wood-composite multihulls of the early 1960s.
Sailing Performance & Handling
On the water, the Wave Rider Catamaran is defined by its remarkable power-to-weight ratio. With a displacement of only 360 pounds and a generous sail area of approximately 160 square feet, the boat boasts a staggering Sail Area to Displacement ratio of 50.58. This translates to immediate acceleration in light air and hair-raising speed as the breeze builds. Under its fractional sloop rig, the boat handles with the characteristic responsiveness of a lightweight beach cat, jumping onto a plane on a reach with minimal wind.
However, sailing a boardless, asymmetric catamaran from this era requires a specific technique. Without deep daggerboards, pointing ability is inherently compromised compared to modern racing catamarans. Owners must foot off and maintain speed to keep the asymmetric hulls generating lift; pinching quickly leads to excessive leeway. The boat's Capsize Screening Ratio of 4.5 reflects its wide beam and inherent stability against rolling, but like all beach catamarans of this weight class, a pitchpole remains a distinct possibility if the bows are stuffed into a wave while sailing downwind in heavy air. The lack of buoyancy in the narrow, early-generation bow profiles means helmsmen must actively manage weight distribution, keeping their weight aft as the breeze increases to keep the bows riding high.
Technical Realities & Known Issues
Given its vintage and construction methods, the Wave Rider Catamaran presents specific technical challenges for modern owners and restorers. The primary concern centers on its composite layup. Using fiberglass skin over a plywood core was an innovative way to achieve high stiffness-to-weight ratios in 1962, but it is highly susceptible to water intrusion. Over several decades, hairline stress cracks in the gelcoat, loose shroud anchors, or poorly sealed gudgeon mounts can allow water to penetrate the plywood core. Once moisture finds its way inside, rot and widespread delamination follow, compromising the structural integrity of the hulls. Restorers must thoroughly inspect the deck-to-hull joints and tap the hulls with a fiberglass hammer to check for the dull, dead thud that indicates soft, rotted plywood underneath.
Another common weak point is the trampoline and its mounting tracks. Because the boat generates significant torsional flex when sailed hard, the aluminum crossbeams and their connections to the fiberglass hulls undergo constant stress. Loose bolts or hairline fractures in the fiberglass mounting areas are common. Additionally, finding original hardware or sails for a boat of this vintage is virtually impossible. Modern owners must rely on custom sailmakers to replicate the fractional sloop sails and adapt contemporary beach cat hardware—such as blocks, rudders, and traveler tracks—to keep these vintage platforms sailing.
The Verdict
The Wave Rider Catamaran remains a compelling piece of multihull history. While it cannot match the raw pointing ability or the structural simplicity of modern rotomolded beach cats, it offers an authentic, high-performance vintage sailing experience. For the dedicated restorer or classic boat enthusiast, it represents a fast, lightweight, and eye-catching day-sailer that captures the pioneering spirit of early catamaran design.
Pros:
- Extremely high sail area to displacement ratio delivers exciting light-air performance
- Boardless, asymmetric hull design allows for easy beach launching and shallow draft
- Wide eight-foot beam provides a stable platform and excellent righting moment
- Lightweight construction makes the boat easy to trail and launch manually
Cons:
- Plywood-cored fiberglass hulls are highly susceptible to moisture intrusion and rot
- Pointing ability is limited compared to daggerboard-equipped catamarans
- Original parts and sails are obsolete, requiring custom fabrication or modern adaptations
- Low-buoyancy bows require careful weight management to prevent pitchpoling in heavy air
