hat a difference 10 feet can make. Ocean Alexander already offers a 90-footer with a four-stateroom layout whose guest spaces would qualify as VIP suites on most yachts. With its OA 100 Skylounge, the builder has added an on-deck master, much like the kind aboard superyachts. That’s one reason why Ocean Alexander calls the 100 Skylounge the entry-level yacht in its six-model mega-yacht series, which stretches up to 155 feet length overall. The 100 Skylounge can be ordered with numerous layouts. Other arrangements include a dual-master, five-stateroom setup, with a full-beam suite in addition to the on-deck master, and an optional twin VIP with two mirrored staterooms amidships. My test yacht had the on-deck master, which is an easy choice in my mind. Wake up surrounded by windows on three sides; have a head with inlaid marble and a walk-in closet; and then take a short stroll to the afterdeck for coffee and croissants. That seems like true luxury, and a surprising amount of it in a 100-foot package. While designer Evan K. Marshall may be known for superyachts, he brings a practical sensibility along with luxurious touches to his designs for Ocean Alexander. Marshall was the first to use the split-level master suite, making use of the bow for a step-down en suite head that includes a bureau with nine backlit and Lucite-faced drawers. The toilet has a separate compartment, as does the shower, and there are two vessel sinks.
