Design and Construction
Both hull and deck are solid fiberglass, and the keel is iron with a fin profile drawing between 5.41 and 5.71 feet depending on load. The 40 percent ballast ratio and 336 displacement-to-length ratio place her among what the design data calls "heavy cruisers," a categorization borne out by her 9,921-pound displacement against 3,968 pounds of ballast. The interior is mahogany, consistent with many production cruisers of the period. A notable wrinkle in the build history is that the Lido was also sold as a home-completion kit, meaning finished-boat quality varies from hull to hull. Of the five Lido-hull boats fitted with a steering wheel, none were built by Bianca Yachts themselves — the yard's own production used tiller steering on this model.
Rig and Handling
The Lido 30 carries a masthead sloop rig with a reference sail-area-to-displacement ratio of 16.6, rising to 19.7 with a 135 percent genoa. Her theoretical displacement-hull speed is 6.5 knots, yet the Volvo Penta diesel drives her at a documented 7.0 knots through a shaft drive. The capsize screening value of 1.95 and a motion comfort ratio spanning 21.9 to 26.0 describe a stable, moderate-motion hull. With a beam of 10.5 feet and a length-to-beam ratio of 2.87, she is beamy for her length without being extreme, and the wetted surface of roughly 279 square feet keeps her in the manageable cruiser bracket. Rigging dimensions are thoroughly standardized: all three halyards run 98.6 feet at 3/8 inch, while sheets and control lines follow fixed spec lengths that any owner can reorder without guesswork.
Accommodations
Below, the mahogany interior reflects the Scandinavian production norm of the era. The 28-gallon water and 11-gallon diesel capacities suit coastal cruising rather than long independent passages, and the 5.41-foot minimum draft admits her to most marinas. The heavy-cruiser displacement and 10.5-foot beam suggest a volume-forward layout typical of the early-1980s Danish cruiser school.
Known Issues
The single documented construction caveat is the home-completion route: because some Lido 30 hulls left the factory as kits rather than finished boats, the quality of joinery, systems installation, and structural finishing on those examples can differ markedly from yard-built hulls. A buyer or reviewer cannot assume uniform build standards across the fleet. The five wheel-steered derivatives built outside Bianca Yachts fall outside the yard's quality envelope entirely and should be assessed as non-standard variants.
Refits and Ownership
Ownership centers on a simple Volvo Penta diesel of 18 horsepower with shaft drive — a configuration that keeps maintenance straightforward. The immersion rate of 864 pounds per inch means load changes are felt but not extreme, and the iron keel, while prone to rust if coating fails, is a straightforward component to inspect and re-coat. The standardized rigging table lets an owner replace running rigging to spec without custom measurement.
The Verdict
The Bianca Lido 30 is a sober, beamy Danish cruiser with a honest heavy-displacement hull and a practical masthead rig. She rewards the careful shopper who verifies build provenance, but the kit-built subset demands closer scrutiny than a normal production boat.
Pros
- Heavy-cruiser stability with 40 percent ballast ratio and 1.95 capsize screen
- Shaft-drive Volvo Penta diesel at 7.0 knots
- Marina-friendly draft from 5.41 feet
- Standardized rigging lengths simplify replacement
Cons
- Home-completion kits produced variable build quality
- Iron keel requires coating vigilance
- Wheel-steered variants are non-Bianca builds of uncertain standard
