Sailing Performance & Handling
Under sail, the Roberts 25 is characterized by a predictable, stiff motion that inspires confidence in novice sailors and families. It was typically offered with several keel configurations, including a fixed fin keel, a shoal-draft variant, and even a twin-bilge keel setup popular in regions with high tidal ranges. Because it was designed with a relatively wide beam of 8' 9" (2.67m) for its length, the boat possesses significant form stability. According to technical archives from the designer, the vessel was intended to handle offshore conditions that would leave lighter, flatter-bottomed trailer-sailers feeling skittish.
The handling is generally described as "truck-like" in the best sense of the word—heavy on the helm but tracking exceptionally well. It does not possess the high Sail Area-to-Displacement (SA/Disp) ratio required for light-air performance; instead, it excels when the breeze freshens. In editorial retrospectives found in Australian sailing publications, the boat is noted for its ability to carry full sail long after its competitors have tucked in a reef. However, its displacement means that in light winds, owners often rely on the auxiliary power—frequently a small inboard diesel like a Yanmar or Volvo Penta, though many were built with an outboard in a well.
Interior Comfort & Variations
The Roberts 25 is frequently cited for having "tardis-like" interior proportions. By utilizing a raised coachroof and generous freeboard, Bruce Roberts-Goodson maximized standing headroom, which is nearly 6 feet in the main cabin—a rarity for a 25-foot boat from this era. The standard layout features a V-berth forward, a compact enclosed head to starboard, and a longitudinal galley. The dinette usually converts into a double berth, allowing the boat to theoretically sleep five adults, though four is the practical limit for cruising.
Several variations of the hull exist, most notably the "Longboat" version. While the standard Roberts 25 features a more traditional sloop rig and yacht-like lines, the Longboat 25 variant often sports a more rugged, motor-sailer aesthetic with a smaller rig and a more pronounced wheelhouse. Prospective buyers should also be aware of the "Roberts 26," which is an evolved version of the same hull form with a slightly extended transom and modernized deck mold. The interior finish varies wildly across the fleet because so many were completed by owner-builders; some feature exquisite teak joinery, while others are utilitarian with painted plywood and basic fiberglass liners.
Known Issues & Buyer’s Checklist
Because the Roberts 25 was a popular choice for home builders, the primary concern for any buyer is the quality of the original construction and the materials used.
- Construction Integrity: For fiberglass models, check for "print-through" or osmotic blistering, though the hulls are generally known for being over-built and thick. For wood-epoxy or plywood versions, a thorough moisture meter test of the hull and stringers is mandatory to check for rot.
- Chainplates and Bulkheads: In many amateur-finished boats, the chainplates were not always perfectly sealed. Inspect the bulkheads where the shrouds meet the wood for signs of water ingress, softening, or delamination.
- Compression Post: Ensure the deck stepped mast has not compressed the cabin top. Check the alignment of the compression post inside the cabin and look for hairline cracks in the gelcoat around the mast step.
- Keel Bolts: On fixed-keel versions, the keel-to-hull joint (the "smile") should be inspected. If the boat has been trailed frequently, the stress on the keel bolts can be higher than on a permanently moored vessel.
Community & Resources
The Roberts 25 benefits from a massive global footprint, supported primarily by the Bruce Roberts Designs office, which continues to provide support and updated plans for many of their classic models. In Australia and New Zealand, where the boat reached its peak popularity, informal owner groups and technical forums provide a wealth of "mod-log" data, detailing everything from rudder redesigns to modernizing the sail plan.
The Verdict
The Roberts 25 remains an excellent entry-level cruiser for those who value safety and living space over regatta trophies. It is a "shorthanded" sailor's dream, providing enough heft to ignore the chop of a busy bay while remaining small enough to maintain on a modest budget.
Pros:
- Exceptional interior headroom and volume for a 25-footer.
- Heavy-weather stability and predictable tracking.
- Available in multiple keel configurations for different cruising grounds.
- Strong secondary market with consistent demand for well-maintained examples.
Cons:
- Sluggish performance in light airs and a lack of pointing ability upwind.
- Wide beam makes "legal" road trailering a challenge in some jurisdictions without permits.
- Variable build quality due to the high number of amateur-finished hulls.
