Design and Construction
Murray Ross's hull form is a study in controlled extremes. The bow section is quite narrow, providing relatively low wave-making resistance and reducing pounding while sailing upwind in waves anchor, while the stern section is wide and flat, making the boat easy to control sailing fast downwind. Those two choices suit a light-displacement hull: the design is marked by light weight and moderate sail area, with a displacement-to-length ratio of 98 and a sail-area-to-displacement ratio of about 24. The 420 sq ft of sail on a 26.58 ft waterline gives the 930 a PHRF rating between 96 and 120 depending on region. Solid fiberglass makes up both hull and deck, with lead on the fin keel and a transom-hung rudder behind.
Rig and Handling
The boat is fractionally rigged and carries a conventional spinnaker pole with a symmetric spinnaker. The distinctive rigging choice is an unusual feature required for class racing: the jib is sheeted to a self-tacking traveler car, which keeps foredeck work minimal in fleet competition. In its standard form the 930 is a light-air performer that rewards clean upwind work; the narrow entry reduces pounding in a chop, and the broad transom lets her run off under spinnaker without a nervous helm.
Accommodations
Below, the interior is comfortable, including fitted berths for five, a two-burner stove, galley with sink, and a head. The berth count is no accident — the five berths are required for racing as well as cruising, so the accommodation is integral to class compliance rather than a cruising afterthought. The layout serves double duty as a weekender and a crewed race boat.
Known Issues
The standard engine is an outboard in a well, and class rules require that this unit must not be removed for racing. A few boats were built with small inboard diesel engines instead, a deviation from the one-design norm that a buyer should verify against the hull's history. The design's known variance lies in propulsion choice and later modification, not in the molded hull or deck.
Refits and Ownership
A lively modification culture has grown around the 930. Some boats have been modified to increase downwind performance with a prod — sometimes articulating — and gennakers, and a common trend is to also fit a masthead spinnaker halyard so masthead spinnakers and gennakers can be hoisted. To control those more powerful sails, heavier and deeper keels must also be fitted, which also increases heavy-weather upwind performance. Carbon fibre masts are becoming common place among modified 930s too. With gennakers and the heavier keels, speeds in excess of 20 knots can easily be sustained for long periods given the right wind angle and strength. A box rule is under development for the Ross 930 Modified so these boats can run as their own class alongside the standard fleet, as currently they sail as a sort of outlaw class.
The Verdict
The Ross 930 is a thoughtful 1980s one-design that punches above its 30 ft length: a narrow bow and flat stern make it both kind upwind and steady downwind, while the self-tacking jib keeps the boat manageable short-handed or fully crewed. The modification path is well established for those who want more, but the stock boat is a coherent racer-cruiser.
Pros
- Narrow bow reduces pounding upwind and lowers wave-making resistance
- Self-tacking jib traveler simplifies class racing
- Five berths required by class rules make the interior functional for cruising
- Strong modification ecosystem with defined keel and rig upgrades
Cons
- Outboard-in-well standard power is class-locked and not removable for racing
- Only a few boats received inboard diesels, complicating spares for that minority
- Modified fleet sails outside formal class structure pending box-rule adoption
