The M58 comes in both a flybridge and sedan version, and with her swim platform extended, she measures 64 feet 7 inches length overall. Zurn calls the hull design on this Downeast-style yacht more of a planing hull form than semi-displacement. The vinylester resin hull (cored with Corecell throughout) has 16.5-degree transom deadrise and a fine entry.
With that hull form and standard twin 725 hp Volvo Penta D-11 IPS2 950s, the M58 will reportedly top out at 27 knots and cruise at 23 knots. However, owners can match their speedster status with one of three other power options as well. To bump the yacht’s maximum and cruise speeds up 2 knots each, owners can go with twin Volvo Penta D-13 IPS3 1050s. The yacht’s third power option, Volvo Penta D-13 IPS3 1200s, will reportedly push the M58 to a 32-knot top speed and a 27-knot cruise. Finally, the utmost power comes from twin 1,000 hp Volvo Penta D-13 IPS3 1350s that provide a 35-knot top speed, Zurn says. With that option, she will cruise at 30 knots for a 750-nautical-mile range.
As for layout, the M58’s glass doors leading into the deck house “all but disappear,” Zurn says. This allows for clear sightlines from the aft cockpit to the forward helm station, a design aspect Hylas clients have said they wanted. Zurn designed the yacht’s galley aft for this reason, and opposite the helm is a settee with table. And since the galley’s aft window lowers into the counter to form a cockpit bar, guests can grab a stool to enjoy a cocktail with a breeze.
On the sedan version of the M58, the yacht’s sun deck has two sun pads as well as speakers for sunbathing jams. On the flybridge version, she’ll have a secondary helm station protected by a venturi windshield, and the space will have a Bimini top. On both versions, the deckhouse hardtop extends to cover the yacht’s cockpit, but three sun roofs still let in some rays.
The M58 has a 3-stateroom layout belowdecks, “centered around a lower-deck foyer with a stacked washer-dryer in a locker to port,” Zurn says. A forepeak en suite stateroom has an island queen berth, as does the amidships stateroom. The latter’s berth is awthwartships to starboard, and its head is to port. The yacht’s third stateroom with twin bunks is forward and to starboard, and its head is opposite, doubling as a day head.
Hylas Yachts is planning to launch the M58 in the fall of 2019 and her base asking price is expected to be $2 million.
