It may seem strange to refer to Pentagramma as a low-gross-tonnage yacht, given her anticipated volume of 2,000 gross tons. However, the 269-footer (82-meter) is truly lower than expected for her LOA. More important, though, Pentagramma doesn’t sacrifice creature comforts. In fact, she’s a concept which turns conventional thinking in terms of design and space on its ear.
Pentagramma is the brainchild of Luca Vallebona, a designer perhaps most well-known for the 131-foot (40-meter) Serenity, built by Mondomarine. Meant for an owner’s party of 12, catered to by 25 crew, the new design promises more than adequate accommodations. This, despite the “low” tonnage. For comparison, the 262-foot (80-meter) Chopi Chopi built by CRN has a volume of 2,363 gross tons. Meanwhile, the 276-foot (84-meter) Valerie built by Lürssen comes in at 2,595 gross tons.
Vallebona recognizes that length and volume need not go hand in hand. Furthermore, he realizes that space utilization offers (no pun intended) room for improvement. For instance, the open aft deck cascades down to the water. It does so in asymmetrical fashion, too. Even the aft upper deck—contained within the dark glass grid giving Pentagramma her name—is open. Eschewing rigid design tradition lets guests better enjoy the fresh-air, on-water atmosphere. “Often we hear talk about the extensive use of glass as the solution to the request of higher relations between exterior and interior,” Vallebona explains. “But this is not enough.”
Pentagramma connects guests to the great outdoors while inside in a different way as well. Staterooms flow straight out from the lower deck to the open beach club/swim platform. No hallways, stairs, or saloons are in the way. Neither, interesting enough, is the engine room. This is because Pentagramma employs diesel-electric podded propulsion, wherein the engine compartment is pushed farther forward. (Guests can take a glance into the engine room, though, due to a glass corridor.)
Numerous amenities such as a spa and a 36-foot-high (3-meter-high), atrium-like saloon are aboard Pentagramma as well. Naturally, the owners get an apartment-like suite with a balcony. But, it also gets a shape-shifting hallway-cum-art gallery.
The biggest surprise that Pentagramma has in store is up top. First, the owners and guests can land on the sundeck in the helicopter. Walking aft, they can access a courtyard-like area (above), down two sets of steps partially hidden by a freestanding blue-tone wall. Here, Pentagramma offers a cozy, sunken lounge. Everyone can linger here the rest of the day, or head inside to the cinema or gym.
