The JPK 45 FC is a 45foot fast cruiser launched by JPK Composites in 2017 as the cruising evolution of the yard’s oceanracing hulls, drawn by Jacques Valer, the architect behind every JPK design. Built for long voyages yet rooted in performance, she pairs a balanced hull with robust infused construction and a bright, considered interior — a combination that earned her class victory at the 2024 Rolex Sydney Hobart despite her cruising volume.

Design and Construction

Valer’s hull for the 45 FC carries more curve in the bilge turn and more volume forward than the yard’s pure racing models, while beamy aft sections, long hard chines, and a fin keel with ballast concentrated low down deliver substantial righting moment. The standard fixed bulb keel draws 2.20 m and weighs four tonnes (2 t GS cast-iron blade with a recessed base ideal for spreading grounding loads, plus a 2 t lead bulb); an optional short shoe keel at 1.90 m adds 300 kg and keeps stability nearly identical, improving further with a carbon mast. JPK builds the entire hull and structure in a single vacuum-infusion operation, a method that yields total homogeneity and an overall light yet very resistant shell unlike volume production. High-stress zones — forward keel, hull-bottom structure, mast and chainplate supports, keel base — get high-density impact-absorbing foam in the sandwich; weight is saved only in low-stress topsides and some superstructure. Interior furniture and bulkheads are infused sandwich laminated to hull and deck, contributing to structure; even doors contain foam, and total wood aboard is around 200 kg, with bleached oak veneer finishing.

Rig and Handling

The 45 FC is a fractional sloop carrying a 53 m² mainsail and 60 m² genoa, with a sail-area-to-displacement ratio of 25.6 that test sailors found translated into a slippery, stiff boat. A twin headsail set-up with genoa and staysail furlers led to the cockpit is a useful cruising solution; genoa and staysail halyards return to tension rails on the mast to spare the clutch banks, while spinnaker and gennaker halyards use a dedicated mast-base winch for hoist and drop. Eight clutches per side route running rigging and sheets to two inboard Harken Performa winches, with backstay and runners also fed to those winches. Raised consoles forward of the twin wheels keep essential maneuvers — sheets, reefs, outhaul, tack — close to the helms. A long bowsprit carries asymmetric spinnakers or gennakers and the anchor; the mainsheet fixes to the doghouse so the cockpit stays clear. Writing in a boat test, one reviewer found the helm light, neutral, and responsive, with 8 knots made in 10 knots true at 31–33° apparent upwind.

Accommodations

Below, the saloon is offset and slightly raised over 700 L of water (per manufacturer spec; a test boat listed 800 L) and 300 L of diesel, giving an open, sociable space; large near-vertical coachroof windows and a vertical front face with sunshade provide clear forward vision without glare. The longitudinal galley has a central unit for cooking efficiently when heeled, and numerous handrails with non-slip sole reinforce safety. A large chart table with watch seat, a head/shower at the companionway foot, and a wet-hanging locker sit within the plan. Standard layout has two aft doubles (one convertible to workshop) and a forward owner’s cabin preceded by a transition space with pipe berths; an option places a sail locker and bigger owner’s cabin aft of the anchor locker. The test boat showed three doubles, a Pullman, and a single heads, with the Pullman removable for a second head.

Equipment and Deck

The deck is molded with non-slip grip throughout, a toerail, and a foredeck handrail; the swim ladder doubles as the central aft guardrail section when raised. A deep chain locker stows fenders and warps, while beneath the helms are gas and liferaft lockers (the latter with a hidden pulley flap). An optional composite arch can carry dinghy, solar, wind generator, radar, and antennas — strong enough to stand on or dive from. A rigid doghouse option forms a protected lookout with opening forward pane and keeps the mainsheet clear; standard sprayhood is the alternative.

Known Issues

Test sailors noted the only weak point of the clutch and winch layout: the 90° turning blocks for the headsail sheets and furling lines introduce friction in those leads.

The Verdict

The JPK 45 FC succeeds as a genuine fast cruiser — a performance hull with cruising comfort and a structure built to travel far. She is efficient upwind, stiff, and well-organized on deck, though the furling-lead friction is a minor handling caveat.

Pros

  • Balanced, stiff hull with low-ballast fin keel and short-keel option
  • Single-shot infused sandwich construction with structural interior
  • Twin headsail rig and cockpit-led controls for short-handed cruising
  • Bright, raised saloon and practical longitudinal galley

Cons

  • Friction at 90° turning blocks for headsail sheets and furling lines
  • Optional equipment (arch, rigid doghouse, carbon mast) needed to realize full potential
