Design and Construction
The 48 Open carries forward deck and inverted bows that the builder describes as a resolutely modern and dynamic statement. Beneath that styling, the hulls are narrow at the waterline for sailing performance, then flare out above chines running their length — a shape that keeps wetted surface in check down low while widening living volume up top. The hull and deck are foam-cored and vacuum-infused, and the interior bulkheads, also cored, are reinforced with carbon fiber for added strength anchor. This is composite engineering aimed at weight control rather than brute mass.
Rig and Handling
On the water, the signature double aft helm station places a wheel at each transom, suited to steering at sea and maneuvering in marinas. The standard rig is a fractional sloop carrying an 88-square-meter mainsail and a self-tacking Solent of 42 square meters, with a 135 genoa offered as an option. Electric Harken winches sit just inboard of either wheel, and another set at either end of the transom controls the traveler and mainsheet. Test sailors found the 48 Open delivered consistent speeds from the low 9s well past 10 knots in about 15 knots of wind, and still showed lots of 7s and 8s on the GPS while beating upwind with the self-tacking jib anchor. Cruising at 1,800 rpm returned just over 7 knots under the optional twin 75 hp Volvos, against a 60 hp standard engine.
Accommodations
Five different layouts are proposed across 2, 3, or 4 cabin configurations with berths from 4 to 9, letting owners tailor the boat to cruising or charter use. A salon occupies the bridge deck, with fridges and freezers to starboard and a U-shaped galley whose sink faces aft. The designer centered the saloon around a bar placed in the heart of the space, and large panoramic windows fill the interior with natural light. The starboard forward area is given to a SmartRoom that can be specified as Flexibility — an office, spare bedroom, or storage — or Utility, serving as workshop, storage, or laundry. The owner suite carries its own integrated dressing and is flooded with light from a long hull window and another above the headboard. Woodwork comes in light walnut as standard, with oak available.
The Verdict
The Nautitech 48 Open is a thoughtfully engineered modern catamaran that trades the bulk of older cruising designs for narrow-waterline hulls, vacuum-infused foam construction, and a flexible interior program. She sails with real pace and handles easily from twin aft helms, though her accommodation density and layout variety mean a buyer must choose carefully among the five plans.
Pros
- Narrow-waterline hulls with flared topsides deliver strong sailing performance for a 48-foot cruising cat
- Foam-cored, vacuum-infused hull and deck with carbon-reinforced bulkheads
- Five layouts from 2 to 4 cabins with a configurable SmartRoom for cruising or workshop use
- Twin aft helms and self-tacking Solent make short-handed marina and sea handling straightforward
Cons
- Standard 60 hp single-engine configuration may feel light against the optional twin 75 hp sailed in review
- Dense layout options require careful specification to match owner intent
