Design Brief & Intent
George Kettenburg Jr. designed the PCC to satisfy a growing demand from racers who wanted a boat capable of winning prestigious offshore events, such as the Transpac and the Newport to Ensenada Race, without sacrificing the interior comforts needed for family cruising. At the time, the market was dominated by massive, heavy-displacement cruisers or stripped-out racing machines. The PCC carved out a unique niche by blending light displacement with a refined hull shape. Built on an inverted jig using semi-production methods, the hull construction featured carvel Honduran mahogany planking over steam-bent White Oak frames spaced on tight eight-inch centers. The centerline was fashioned from Douglas fir, while the spars and towering mast were crafted from Sitka spruce. This combination of premium woods created a robust yet remarkably light structure for its 46-foot length, keeping the boat’s displacement at a nimble 20,000 pounds.
Unlike contemporary East Coast designs of the era from Sparkman & Stephens, which favored wider beams and heavier scantlings, the PCC was remarkably narrow, with a beam of just 9.5 feet. This slender profile gave the boat an intimate, linear interior. While modern 46-footers offer cavernous, apartment-like saloons, stepping below on a PCC reveals a traditional "hallway" layout that prioritizes functional offshore safety. There are no wide, open spaces where a crew member can be thrown in a seaway. Instead, handholds are always within reach, and the cabin boasts beautiful mahogany cabinetry, a teak cabin sole, and 6 feet 1 inch of standing headroom in the saloon. Large, bright portlights let in abundant light, a design choice that was highly unusual for the late 1940s and contributed to a remarkably airy feel down below.
Variations & Configurations
As a strict one-design class, the Kettenburg PCC was built to tight tolerances to ensure that racing success depended on seamanship rather than design modifications. Consequently, major structural variations are virtually non-existent. The standard underwater profile features a deep, traditional keel with a cutaway forefoot, carrying approximately 3,800 pounds of external lead ballast to provide the necessary righting moment for its tall fractional sloop rig.
However, individual owners occasionally ordered subtle variations in the cabin trunk and interior finish. A few hulls were built with a slightly higher doghouse to increase headroom for taller owners, though the majority retained the sleek, low-profile coachroof designed by Kettenburg. The interior layouts occasionally saw customized joinery, with some boats configured with additional storage lockers for sails and offshore gear in place of the standard pilot berths. In terms of auxiliary power, early hulls were delivered with a Gray Marine four-cylinder gasoline engine driving a folding propeller, a setup designed to keep drag to an absolute minimum while racing 2.
Sailing Performance & Handling
On the water, the sailing characteristics of the PCC are legendary. With a Sail Area to Displacement (SA/Disp) ratio of 17.39, the PCC is a highly efficient performer in light-to-moderate air. It has a remarkably low wetted surface area due to its narrow hull form, allowing it to ghost along at impressive speeds when wider, modern cruising boats are entirely stalled. This light-air prowess made the PCC a formidable "giant-killer" on the racing circuits of the 1950s.
With a Displacement to Length (Disp/LWL) ratio of 272.48, the boat is categorized as a moderate-to-heavy displacement vessel by modern standards, but in its era, it was considered a light, slippery greyhound. The hull features generous overhangs at the bow and stern, resulting in a relatively short 31-foot static waterline. However, as the breeze freshens and the boat heels, this waterline extends dramatically, significantly increasing the boat's theoretical maximum hull speed.
Because of its narrow 9.5-foot beam, the PCC is initially tender and will heel readily under a sudden gust. However, it quickly finds its "groove" at a specific angle of heel, where its 35% ballast-to-displacement ratio takes over. The deep lead keel provides a powerful, steady righting moment that keeps the boat balanced and stable. A Capsize Screening ratio of 1.4 confirms its excellent resistance to rolling in severe offshore conditions, while a Motion Comfort ratio of 42.45 translates to an exceptionally smooth, soft ride in a head sea. The boat does not slam into waves; rather, its narrow entry slices through chop, and the heavy displacement ensures that the motion is predictable and easy on the crew. Helm feedback is light and precise, and when properly trimmed, the PCC tracks with remarkable directional stability.
Known Issues & Triage
As with any classic wooden vessel approaching its eighth decade, owning a Kettenburg PCC requires a deep understanding of wooden boat maintenance and a commitment to structural preservation. The most prevalent issue facing original or neglected hulls is frame degradation. The steam-bent white oak frames can succumb to rot or develop structural cracks over time, particularly in areas subject to the high stress of the rigging or keel. In many surviving hulls, "sistering"—the practice of installing a new oak frame alongside a damaged original—is common. Prospective buyers must have a specialized wooden boat surveyor evaluate the integrity of these sistered frames and check for further structural failures.
The hull fastenings represent another critical area of concern. The original silicon bronze wood screws used to secure the mahogany planks can suffer from dezincification (often called "pink rot"), where the zinc leaches out of the alloy, leaving a weak, porous copper fastener that can shear under load. Complete refastening of the hull—a labor-intensive process involving the extraction and replacement of thousands of bronze screws—is a standard milestone in a PCC’s lifecycle.
The keel-to-deadwood joint must also be examined closely. Over time, water can seep into the wood surrounding the bronze or iron keel bolts, leading to localized rot and "weeping" at the joint when the boat is hauled out. Resolving this issue often requires dropping the lead keel, replacing the keel bolts, and rebuilding any damaged wood in the deadwood area. Lastly, the deck and cabin trunk, which were originally built from plywood and covered in painted canvas, are prime candidates for fresh-water leaks. If the canvas or subsequent fiberglass overlays crack, fresh water will rapidly rot the plywood underneath, particularly around chainplate penetrations and hatch coamings.
Modernization & Upgrades
In recent decades, dedicated caretakers of the surviving PCC fleet have executed extensive restorations to modernize these vessels for modern cruising and classic yacht racing. The most common mechanical upgrade is repowering. The original Gray Marine gasoline engines, while simple, are now obsolete and present safety and parts-availability challenges. Modern owners typically replace them with small, lightweight, fresh-water-cooled diesel engines, such as a 25-horsepower or 30-horsepower Beta Marine or Westerbeke diesel. These modern powerplants fit neatly into the narrow bilge spaces, offering vastly superior reliability, safety, and fuel economy.
Electrical and plumbing systems are also prime targets for modernization. Restored hulls generally receive complete rewiring with marine-grade tinned copper wire, high-output alternators, and modern battery management systems. While some owners have experimented with lithium iron phosphate (LiFePO4) batteries to save weight, the traditional lead-acid or AGM banks are often retained to help maintain the boat's necessary low-down ballast. Plumbing upgrades typically involve replacing old galvanized pipe and copper lines with flexible PEX tubing and installing reliable electric bilge pumps alongside high-capacity manual pumps.
Rigging upgrades have also helped keep these classics active. While purists maintain the beautifully varnished hollow Sitka spruce masts, the standing rigging is almost universally upgraded from older galvanized wire to 1x19 stainless steel or modern synthetic equivalents, paired with high-performance running rigging. Upgrading the deck hardware to modern, self-tailing bronze winches allows these boats to be easily managed by short-handed or family crews.
The Verdict
The Kettenburg PCC is a yacht for the purist, a striking piece of maritime history that rewards its owner with unmatched aesthetic beauty, a sublime feel at the helm, and a distinguished racing pedigree.
