The Cal 29 is an American cruiserracer designed by William “Bill” Lapworth and built by Jensen Marine from 1968 to 1972. Roughly 600 to 800 examples were completed during that fiveyear run. One of the early models in the Cal line, it belongs squarely to the marque’s Southern California heyday and Lapworth’s long design partnership with Jensen.

Conceived for coastal cruising with genuine racing ambitions, the Cal 29 typically carries a PHRF rating in the 168–180 range. Its combination of a responsive sailing design and useful accommodations remains central to its appeal.

Design and Construction

The Cal 29 measures 29 feet overall, with a 24-foot waterline, a 9-foot-3 beam, and a 4-foot-6 draft. It displaces 8,000 pounds and carries 3,350 pounds of lead ballast—just under 42 percent of its displacement.

The boat combines a solid fiberglass hull with a fixed fin keel and spade rudder. That configuration was thoroughly modern for a late-1960s 29-footer and supports the design’s dual cruiser-racer purpose. The relatively shallow draft also keeps the Cal 29 accessible to shallow coastal harbors, while the substantial lead ballast gives it a firm footing.

Jensen built the early Cal models in an open-air Southern California field to keep costs down, earning the line its “backyard boats” nickname. The Cal 29 comes from that era of lean, volume-produced fiberglass construction.

Rig, Performance, and Handling

The 41-foot masthead-sloop rig stands over the 24-foot waterline. Standard rig dimensions are:

  • I: 37 feet
  • J: 12.33 feet
  • P: 31.67 feet
  • E: 12.25 feet

The resulting sail plan was intended to combine reaching speed with manageable shorthanded handling. Period assessments credit the design with lively sailing qualities suited as readily to a PHRF racecourse as to cruising.

The fin keel and spade rudder give the boat the directional sensitivity and turn-in response expected of a racer. Its 6.56-knot hull speed, derived from the waterline length, marks the upper limit of its effortless pace under sail.

Accommodations and Capacity

Within its 29-foot envelope, the Cal 29 is praised for having a spacious interior for its size. That is a meaningful attribute in a boat with a beam of just over nine feet and a compact overall length.

The cruiser-racer brief did not require trading away all belowdecks volume for sailing performance. The same Lapworth hull that feels lively upwind also provides a livable cabin for coastal passages. This balance of room and responsiveness is at the heart of the boat’s enduring appeal as an early Cal that punches above its length.

Fuel and water capacities are both 20 gallons, reflecting the Cal 29’s coastal-cruising purpose rather than a focus on long-range voyaging.

Engine and Known Issues

The defining mechanical system is the 30-horsepower Universal-Atomic Atomic 4 gasoline engine. Because it is a gasoline powerplant rather than a diesel, it shapes both winterization and fire-safety considerations for an owner.

Any Cal 29 still afloat will have systems that are decades old, and the design requires maintenance on aging systems, including the Atomic 4 and original rigging. Standing rigging dating from the 1968–1972 production period warrants close inspection regardless of any cosmetic refit above the waterline. The engine likewise needs to be kept current.

Ownership Notes

With approximately 600–800 hulls produced, the Cal 29 is numerous enough that spare parts and fellow-owner knowledge circulate. Its modest tankage and gasoline engine remain important practical considerations, but its production run also gives today’s owners a meaningful community of similar boats.

The Verdict

The Cal 29 is a Lapworth-designed cruiser-racer that combines lively performance with a roomy cabin in a compact, solid-fiberglass hull. Its early-Cal pedigree and PHRF competitiveness make it a satisfying choice for sailors who want to race and cruise without moving up to a larger boat, provided they keep the aging Atomic 4 and rigging honest.

Pros

  • Lively sailing qualities and a competitive PHRF rating around 168–180
  • Spacious interior for a 29-foot cruiser-racer
  • Solid fiberglass hull with a 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 20-gallon water capacities confine it to coastal use
