Hull, Construction, and Structural Design
The 588's hull is a balsa-cored fiberglass sandwich laminate set in polyester resin with the exterior skin laid in vinylester to resist osmosis. Below the waterline the layup transitions to solid glass. Chainplate areas — among the highest-stress zones on any sailing yacht — receive a reinforcement of carbon fiber, while interior bulkheads are vacuum-bagged composite structures fully tabbed into the hull. The cast-iron keel comes in three variants: a shallow L-shaped version drawing seven feet five inches, a standard fin drawing eight feet eight inches, and a deep T-shaped bulb drawing nine feet four inches. All three are bolted to large metal backing plates bedded in epoxy and surrounded by a structural floor grid, a detail that speaks to the seriousness with which Hanse approaches keel-to-hull integrity on a fifty-thousand-pound boat. The single spade rudder is cored fiberglass with an aluminum stock and frame.
At 56 feet 5 inches on the water and 49 feet 8 inches on the line, the 588's displacement-to-length ratio of roughly 183 sits firmly in the light end of the moderate band — a figure that helps explain the boat's lively performance without compromising offshore seaworthiness. The comfort ratio of 34 places it squarely in the moderate bluewater cruiser range, and the capsize screening figure of 1.85 confirms it is well-suited for ocean passages.
Deck Layout and Cockpit Ergonomics
From the deck up, the 588 presents a study in functional minimalism. A straight bow and stern, ample topsides, wide beam, maximum waterline, minimalist deck jewelry and a razor-sharp sheer give the boat its business-like visual character — and those same choices pay direct sailing dividends. The flush deck is rimmed by a raised bulwark that frames it visually and adds real security in rough conditions; the absence of scuppers means water taken aboard is routed aft rather than streaming down the topsides.
All lines run aft from the mast belowdecks to rope clutches and Lewmar winches positioned within easy reach of both helmsmen. The cockpit features twin Carbonautica wheels with independent Lewmar steering systems, and forward of the wheels sit twin cockpit tables either side of a central walkway that gives unobstructed passage from the companionway to the hydraulically controlled fold-down transom. Beneath the cockpit, a dinghy garage remodeled from the 575 accommodates a broader range of tenders. An optional fiberglass T-Top hardtop with retractable canvas panel and windscreen is available for those who want cockpit shelter; the base configuration makes do with a foldaway bimini. High cockpit coamings provide comfortable seating for guests well clear of the working crew.
Forward of the cockpit a robust grabrail runs along each side of the coach roof — a feature worth noting in an era of naked foredecks. At the bow, a segregated sail locker can be configured as crew quarters. Six hull windows on each side are the largest possible without compromising structural integrity, admitting generous light while breaking up the visual mass of the topsides.
Rig and Sailing Performance
The 588 is rigged as a fractional sloop on a triple-spreader Seldén aluminum spar with no traveler, a configuration that moves mainsheet load directly to cockpit winches in the German double-ended style. The self-tacking jib on a Seldén Furlex manually controlled furler and an optional Code 0-type genoa on a Reckmann electric furler form the twin-headsail setup that constitutes the standard offshore sail plan, with all canvas built from composite-laminate sailcloth by Elvström. The main is a fully battened sail stowed in an in-boom FurlerBoom system that eliminates the mainsail stack entirely.
Sail Magazine's sea trial, conducted with the shallowest keel variant and a slightly truncated rudder, produced results that surprised even the reviewer. Flying the full main and Solent jib in thirteen knots of true wind, the boat comfortably held thirty degrees off the apparent wind at up to seven and a half knots. Cracking to forty-two degrees apparent, the speedo reached nine knots; at a fifty-five-degree close-reaching angle it surged repeatedly to 9.9 knots. On a broad reach at 130 degrees with only the Solent jib set alongside the main, boat speed held in the seven-point-eight to eight-point-two-knot range. Under the mainsail alone, the 588 still managed a maximum of 6.8 knots — a testament to how well the in-boom system preserves sail shape. The calculated hull speed of 9.45 knots is thus genuinely accessible in normal sailing conditions.
The helm carries some weight, but the overall feel at all angles is responsive and rewarding — a boat that asks the helmsman for attention and returns it with directional stability through gusts and wind shifts. The sail area-to-displacement ratio of just under 20 keeps the 588 in the high end of "reasonably good performance" territory, well-powered but not a handful in a breeze.
Accommodation Flexibility
Perhaps the most commercially distinctive aspect of the 588 is the sheer scale of its interior options. Twelve different layouts encompass up to five double cabins, with configuration choices that include splitting the forward owner's stateroom into two smaller staterooms, choosing between a U-shaped galley or a walk-through version with an island, adding a separate crew or passage cabin, or varying the orientation of the aft berths. A fully soundproofed forward owner's stateroom with a gasketed door is a standard feature, emphasizing that Hanse treats acoustic comfort as part of the build quality.
The aft double cabins each offer ensuite heads with separate shower stalls, good natural light, ventilation, and substantial headroom. Upholstery colors, fabrics, carpeting, and joinery can all be individually selected, meaning no two 588s need be alike. The saloon is brighter and more open than the 575 it replaced, benefiting from larger hull portlights and twenty deck hatches — though the hatch count will require attention in squall conditions.
Cruising World's judge noted that the noise level under power was comparable to the highest quality and most expensive yachts in the BOTY fleet, attributing it to tight tolerances throughout the assembled interior. It is a telling indicator: on a production boat this size, unwanted harmonics typically betray compromised fit and finish. Their absence here suggests disciplined manufacturing.
Motoring and Systems
The standard engine is a 110hp Volvo diesel connected to a three-blade Flexofold folding prop via conventional shaft drive. An optional 150hp plant is available for owners who prioritize motoring range or charter use. In testing, the boat reached 7.5 knots at 1,920 rpm punching into fifteen knots of headwind, and made 9.4 knots in flat water at 2,150 rpm — figures well above what one might expect from a 50,000-pound displacement hull. Maximum throttle yielded 10.2 knots at 2,740 rpm. Optional bow and stern thrusters (Quick retractable units) make short work of marina maneuvering at this length. The engine compartment is well insulated and accessible on three sides, a practical consideration for offshore maintenance.
Fuel capacity of 137 gallons and water capacity of 203 gallons support extended coastal or bluewater use with multiple cabins occupied.
The Verdict
The Hanse 588 is an honest achievement in the large-production-boat segment: a yacht that replaces a successful predecessor with thoughtful improvements and enhanced finish quality rather than mere styling updates. Judel/Vrolijk & Co.'s hull design delivers genuine performance across points of sail — not just the upwind numbers but the reaching and off-wind speeds that reward blue-water passage making. The interior flexibility is unmatched in its class, giving buyers the rare ability to genuinely personalize a mass-production boat. What keeps the 588 from being a pure racer-cruiser is the same thing that makes it compelling as a liveaboard or long-passage yacht: weight, volume, and the structural seriousness that both imply.
