Design and Construction
The Cal 35's formula leaned on moderately light displacement, longish waterlines, a fin keel, and a high-efficiency rudder, though at 13,000 pounds her displacement/length ratio of 242 reads heavy by modern labels displaces just 2,000 pounds less than the Cal 40. Her ballast/displacement ratio sits at 40 percent, with 5,200 pounds of lead encapsulated in a resin matrix within a fiberglass keel rather than bolted externally. The hull itself is solid glass, while the deck is plywood cored; the hull-to-deck joint turns inward on the hull and downward on the deck, bedded with sealant and capped by a perforated aluminum toerail bolted both horizontally and vertically. Owners with boats 20 years old or more reported no deck leaks, a notable result for a cored deck of that era.
Her keel took a middle route in keeping with a "please everybody" mission: a conservatively thick section and long chord length rather than a skinny high-aspect foil. The hull shape is clean and surf-ready but narrower with softer chines than most boats that followed, and the entry was sharpened materially to help in slop and chop. A straight sheer, elongated stem, almost no counter, and a delicately reversed transom give her a restrained profile, with Dorade boxes flanking the companionway as part of the look. That full entry also helps her ride high and dry while surfing down waves, though flat sections forward of the keel can pound — a trade that nonetheless yields crisp, fluid motion.
Rig and Handling
The Cal 35 carries a masthead sloop rig with aluminium spars, inboard shrouds that tighten sheeting angles and let crew walk the side decks, and a mainsail smaller than the foretriangle yet large enough for pleasurable main-alone sailing. The big spade rudder and smallish fin combine to give a very small turning circle, a real asset in close quarters. Upwind in light air or chop she is at her worst, but with the wind free and strong she gets up and goes; Practical Sailor pegged her around 160 under PHRF while reference data lists a racing average of 136. She is also considered somewhat tender, a condition tied to the lower effective density of the encapsulated fin.
The standard mainsheet arrangement drew fire: it used what amounted to two travelers and was judged over-complicated by several sailors. Several owners relocated the pedestal four inches forward and fitted a 36-inch wheel in place of the standard 28-inch wheel, a telling correction to helm ergonomics rather than to sailing character.
Accommodations
After 50 boats sold in the first three years, the interior was redesigned — the original layout placed a head aft with galley opposite, while the Mark II shifted to a quarter berth aft, two settee berths in the saloon, and a substantial platform double in the forepeak, with the head/shower forward of the saloon and double sinks on the centerline. The drop-leaf saloon table replaced a clumsy mast-mounted table, and ventilation runs better than average via Dorade vents, six opening ports, and an opening overhead hatch. The Mark II galley sits to port with a three-burner alcohol-fired stove and oven, and an aft double berth to starboard was optional. One persistent annoyance: the icebox is large but not well-insulated, and the standard forepeak hatch leaks.
Known Issues
Beyond the leaking forepeak hatch and poor icebox insulation, documented water ingress traces to the design of the anchor locker drains and the mounting for the cutless bearing strut, as one owner reported major uptake by those paths. Later boats built in Tampa after 1982 drew owner reports of blistering and other problems, so hull pedigree matters by build location and date. No owner reported deck leaks despite the plywood-cored top, which keeps the hull-to-deck joint in the clear.
Refits and Ownership
The most common owner-driven change was the wheel and pedestal relocation already noted; otherwise the boat's well-built reputation and quiet,R smooth power plant anchor ownership. The standard Universal 32-hp four-cylinder diesel pushes her past her 7-knot hull speed and burns less than a gallon per hour at cruising speed, and several owners rated noise and vibration as very smooth and quiet.
The Verdict
The Cal 35 is a thoughtfully conceived cruiser-racer from the close of the Lapworth-Jensen line: encapsulated lead in a fiberglass fin, a cored deck that does not leak, and a hull that surfs but pounds. She rewards a free wind and punishes light-air beating, and her Mark II interior is a genuine step forward. The weak spots are specific and inspectable rather than systemic.
Pros
- Final Lapworth-Jensen design with encapsulated-lead fin and solid-glass hull
- Cored deck with no reported leaks after 20+ years
- Small turning circle from spade rudder and small fin
- Smooth, quiet Universal 32-hp diesel exceeding 7 knots on less than 1 gph
- Mark II interior a real improvement over mast-mounted table original
Cons
- Tender performance; weak upwind in light air or chop
- Standard forepeak hatch leaks; icebox poorly insulated
- Anchor-locker drains and cutless-bearing strut mount documented water ingress
- Tampa-built post-1982 boats reported blistering
- Original mainsheet layout over-complicated with two travelers
