The Cal 29 is an American cruiserracer designed by William "Bill" Lapworth and built by Jensen Marine from 1968 to 1972, with roughly 600 to 800 examples completed during that fiveyear run. As one of the early models in the Cal line, it sits squarely in the marque's Southern California heyday under Lapworth's long design partnership with Jensen. At 29 feet overall with a 24foot waterline, a 9foot3 beam, 8,000 pounds of displacement, and 3,350 pounds of lead ballast, the boat was conceived for coastal cruising with genuine competitive racing ambition under PHRF, where it typically rates in the 168–180 range.

Design and Construction

The Cal 29 combines a solid fiberglass hull with a fixed fin keel and a spade rudder, a configuration that reads as thoroughly modern for a late-1960s 29-footer and underpins its dual cruiser-racer brief. Lapworth's hand is evident in the proportions: the 41-foot masthead-sloop rig steps over a 24-foot waterline, and the 4-foot-6 draft keeps the boat accessible to shallow coastal harbors while the lead ballast at just under 42 percent of displacement gives it a firm footing. Jensen built the early Cal models in an open-air Southern California field to keep costs down, a practice that earned the line its "backyard boats" nickname, and the Cal 29 belongs to that era of lean, volume-produced fiberglass construction.

Rig and Handling

As a masthead sloop the Cal 29 carries a standard I dimension of 37 feet, a J of 12.33 feet, a P of 31.67 feet, and an E of 12.25 feet, yielding a sail plan built for both reaching speed and manageable shorthanded handling. Period assessments credit the design with lively sailing qualities that suit the PHRF race course as readily as the cruising anchorage. The spade rudder and fin keel give it the directional sensitivity and turn-in response expected of a racer, while the 6.56-knot hull speed derived from the waterline length marks the upper bound of its effortless pace under sail.

Accommodations

Within its 29-foot envelope the Cal 29 is praised for a spacious interior for its size, a meaningful attribute given the beam of just over nine feet and the compact LOA. The cruiser-racer brief means the belowdecks volume was traded against nothing in the way of sailing performance — the same Lapworth hull that feels lively upwind also carries a livable cabin for coastal passages. This balance of room and responsiveness is the core of the boat's enduring appeal as an early Cal that punches above its length.

Known Issues

Any Cal 29 now afloat will have systems decades old, and the design requires maintenance on aging systems such as the Universal-Atomic Atomic 4 gasoline engine and the original rigging. The Atomic 4 is a gasoline powerplant rather than diesel, which shapes both winterization and fire-safety considerations for an owner, and the standing rigging from the 1968–1972 build period warrants close inspection regardless of any cosmetic refit above the waterline.

Ownership Notes

With approximately 600–800 hulls produced, the Cal 29 is numerous enough that spare parts and fellow-owner knowledge circulate. The 20-gallon fuel and 20-gallon water capacities reflect its coastal-cruising intent rather than long-range voyaging, and the 30-horsepower Atomic 4 remains the defining mechanical system an owner must keep current.

The Verdict

The Cal 29 is a Lapworth-designed cruiser-racer that delivers lively performance and a roomy cabin within a compact, solidly built fiberglass hull. Its early-Cal pedigree and PHRF competitiveness make it a satisfying boat for the sailor who wants to both race and cruise without stepping up to a larger platform, provided the aging Atomic 4 and rigging are kept honest.

Pros

  • Lively sailing qualities with a competitive PHRF rating around 168–180
  • Spacious interior for a 29-foot cruiser-racer
  • Solid fiberglass hull with fin keel and spade rudder
  • Early Lapworth/Jensen design with a meaningful production run

Cons

  • Aging Atomic 4 gasoline engine demands ongoing maintenance
  • Original rigging from the 1968–1972 period requires inspection and likely renewal
  • Limited 20-gallon fuel and water capacity confines it to coastal use
