Jensen Cal 28 Sailboats for Sale

The Jensen Cal 28 is one of those small American sailboats that earned its place in yachting history by doing something genuinely new. Designed by Bill Lapworth and originally manufactured by Jack Jensen at his Jensen Marine Corporation, the boat was first built in 1963 and marketed originally as the California 28 before the name settled into the nowfamiliar Cal 28. Cal Yachts built the design in the United States between 1963 and 1969, completing 347 examples before production ended; a licensed version was also built by Calgan Marine in North Vancouver, Canada. As the first Lapworth design to incorporate a spade rudder, and the prototype for the radical finandspade configuration later seen on the celebrated Cal 40, the Cal 28 helped set the template for the modern racercruiser.

Jensen Cal 28 Buyer's Guide

Shopping the used market for a Jensen Cal 28 means looking for one of 347 finished examples, a design now out of production and fairly rare in captivity. Built by Cal Yachts in the United States between 1963 and 1969, with a licensed Canadian version from Calgan Marine in North Vancouver, the boat is an American sailboat of fiberglass construction with a masthead sloop rig and the distinctive fin keel and internally mounted spade rudder that made her a prototype for later Lapworth designs. She is a monohull of 28 feet overall, 9-foot beam, and 4.5-foot draft, displacing 6,000 pounds with 2,200 pounds of lead ballast.

Layouts on the Used Market

Because the original was a raised-deck model alongside the Cal 20, Cal 2-24, and Cal 25, the Cal 28 offers the volume that raised-deck styling allows in a 28-foot racer-cruiser. The factory described her as a small recreational keelboat with cruising provision for 28 gallons of water and 18 gallons of fuel, so layouts center on a modest forward and saloon arrangement served by those tanks rather than expansive cruising accommodations. Buyers should expect the period racer-cruiser compromise: space enough for weekends and short coasts, not a bluewater interior.

Equipment and Common Upgrades

The most consequential factory option was a Universal Atomic 4 gasoline engine with a V-drive, and any buyer should confirm whether the example retains this original auxiliary or has been repowered. Beyond that single significant mechanical item, the available material leaves equipment general; the Canadian-licensed boats share the same core design, so regional differences are about condition rather than fitted gear. A used Cal 28 should be judged on hull integrity and rig originality before weighing smaller comforts.

What to Inspect

Inspection should follow normal fiberglass practice for a 1960s Lapworth hull: check the fin keel joint and the internally mounted spade rudder stock for past damage or repair, and verify the Atomic 4 installation if fitted. With only 347 built and the design out of production, a careful survey of the lightweight hull and original rudder is the best protection against a scarce boat's hidden history.

Availability and Buyer's Takeaway

The Cal 28 is typically found in the United States, the market where Cal Yachts built the majority of the class. For a buyer, the short checklist is plain:

  • Confirm original raised-deck fiberglass hull and fin-keel configuration
  • Verify rudder and keel attachments on a lightweight 6,000-pound hull
  • Check for the Universal Atomic 4 or a sane repower
  • Expect rarity: 347 examples mean patience in the search
