Design and Construction
Both hull and deck are fibreglass, and each is a sandwich construction — a build method the original review noted as improving the indoor climate below anchor. The solid-cored shell wraps a lead-ballasted fin-keel hull of 8,157 pounds displacement, and the transom-hung rudder follows the period Australian practice of keeping steering gear simple and accessible. The length-to-beam ratio of 2.95 and a displacement-length ratio of 224 place her squarely in the "moderate racer" category the source assigns to that DL figure, while a wetted surface of roughly 290 square feet and an immersion rate of about 912 pounds per inch describe a hull that sits heavily and moves predictably under load.
Rig and Handling
The Viking 30 is a masthead sloop carrying sheet spec that tells you something about her rig scale: jib and genoa sheets run 30.5 feet at a half-inch diameter, the mainsheet stretches 76.3 feet, and the spinnaker sheets reach 67.1 feet, all on 12 mm line anchor. The fin keel and transom-hung rudder combination, paired with the moderate beam, gives a boat whose theoretical displacement hull speed is 6.7 knots. A capsize screening value of 2.05 means she would not qualify for ocean racing under that metric, and the Motion Comfort Ratio of 20.8 describes a moderately soft motion rather than a heavy-ocean passage profile.
Power and Propulsion
Some examples may be fitted with an inboard Yanmar 2GM diesel turning a saildrive, a transmission type worth noting because it places the gearbox inside the hull footprint rather than on a conventional shaft log. With that engine the calculated maximum speed is about 3.9 knots, well below the theoretical hull speed under sail — a figure that reflects the modest auxiliary rather than any deficiency in the underbody.
Known Issues
The sandwich hull and deck construction, while credited with a better cabin climate, is the one area where a buyer should understand the boat differs from a solid-layup contemporary; any core moisture intrusion would be a hidden-rot scenario rather than a surface cosmetic one.
The Verdict
The Viking 30 is a small, scarce Lexcen design that pairs a sandwich-constructed fibreglass hull with a fin-keel, transom-rudder underbody and a masthead rig scaled for club racing and coastal cruising. She is not an offshore campaigner by the capsize-screening measure, but her comfort ratio and immersion rate suggest a steady, load-stable platform for sheltered-water sailing.
Pros
- Sandwich hull and deck construction for improved cabin climate
- Fin keel under five feet draft for easy marina access
- Masthead rig with full spinnaker capability
- Moderate-racer DL ratio of 224
Cons
- Fewer than 100 built, limiting spares and community knowledge
- Capsize screening value of 2.05 excludes ocean racing
- Saildrive transmission complicates driveline service versus shaft drive
