Sailing Performance & Handling
The Rival 36 is an unapologetic heavy-displacement cruiser with a Displacement/Length ratio of approximately 317, placing it firmly in the category of vessels built for oceanic survival rather than light-air agility. Its hull form, featuring a deep fin keel or a Scheel keel paired with a substantial skeg-hung rudder, provides the directional stability and "fingertip balance" for which Peter Brett designs are famous. According to technical assessments by Sailboat Cruising, the Sail Area/Displacement ratio of 15.7 suggests the boat requires a stiff breeze to reach its hull speed of roughly 7 knots.
In a seaway, the 36 is noted for its sea-kindliness; a high Comfort Ratio of 30.4 ensures a predictable, easy motion that minimizes crew fatigue during long passages. While it lacks the acceleration of modern fin-and-spade designs, its ability to carry momentum through chop and maintain a steady course on a beat makes it a favorite for solo or short-handed sailors. The rig was typically a masthead sloop, though many were commissioned as cutters to provide more versatile sail plans for offshore work.
Interior Comfort & Variations
The interior of the Rival 36 is famous for the "keyhole" bulkhead, a structural and aesthetic hallmark that provides immense rigidity to the hull while creating a distinctive visual transition between the saloon and the forward accommodations. The joinery is typically finished in high-quality teak or "blonde" teak, with many examples still retaining a showroom-like finish decades later due to the use of thick, hardwood-faced marine plywood.
The layout is traditional and functional for offshore life, featuring a secure U-shaped galley to port and a substantial, forward-facing chart table to starboard. Headroom is generous for a boat of this era, topping out at approximately 6 feet 3 inches in the main saloon. Three primary underwater configurations were offered: the standard deep fin keel (6' draft), a shoal-draft Scheel keel, and the 36C centerboard version. The centerboard variant is particularly notable for its external stub keel and grounding shoe, allowing the boat to dry out safely in tidal harbors.
Popular Mentions & Media
While the Rival 34 gained the most fame for its 1976 OSTAR victory (sailed by Geoff Hales in Wild Rival), the 36 inherited that offshore pedigree. It is frequently cited in cruising literature as the "refined" Rival, benefiting from the lessons learned on the 34. The model maintains a strong presence in the blue-water community and is often featured in long-distance voyaging logs and technical sailing journals as a benchmark for small-ship structural integrity.
Known Issues & Buyer’s Checklist
- Osmosis: While Rival hulls were heavily laid up, they are not immune to the osmotic blistering common in 1980s GRP. A professional moisture meter test is essential, though many hulls have already undergone preventative epoxy treatments.
- Engine Serviceability: Original models often featured the Bukh 20 or Volvo Penta MD2030. Buyers should check for aging cooling systems and sail-drive seals (if applicable), though many have since been repowered with more modern Beta or Perkins units.
- Chainplates and Leaks: Like any traditional deck-stepped or through-deck rig, the chainplate seals and "keyhole" bulkhead tabbing should be inspected for signs of moisture ingress, which can lead to core saturation in the balsa-cored decks.
- Standing Rigging: Many 36s were fitted with substantial masthead rigs that place significant loads on the hull-to-deck joint. Evidence of "crazing" or stress cracks around the stay attachments warrants a closer look at the internal backing plates.

The Verdict
The Rival 36 is a stout, traditional cruiser for those who prioritize safety and structural integrity over modern interior volume and planing speeds.
Pros:
- Exemplary build quality with Lloyd's 100A1 certification.
- Superb heavy-weather handling and sea-kindly motion.
- Exceptional interior joinery and functional offshore layout.
- Available in multiple keel configurations for varied cruising grounds.
Cons:
- Relatively sluggish in light winds (below 10 knots).
- Traditional "tucked-in" stern limits aft cabin space compared to modern designs.
- Requires more maintenance than modern, simpler builds due to the complexity of the internal woodwork and aging systems.
