2026 Schionning Prowler 1500 | Iona

Iona, a Schionning Prowler 1500 currently in build with Pantawee Marine in Pattaya, Thailand, presents a unique opportunity to own a semi-custom power catamaran tailored to your vision. Scheduled for delivery at the end of 2026, she combines striking contemporary design with proven ocean-going performance.

The Prowler 1500’s distinctive square bows and sweeping wraparound cabin windows create a bold modern profile while flooding the interior with natural light. A seamless foredeck runs to the forward edge of the bridgedeck, offering a large platform ideal for sunbathing, enjoying a glass of champagne at anchor or carrying a tender and water toys with ease.

The open-plan interior takes full advantage of Iona’s notably wide hulls, significantly broader than her Alaskan sisterships. This extra beam translates into exceptional interior volume and layout flexibility, eliminating the enclosed feeling often associated with hull accommodations.

IONA has been designed with extended cruising in mind, offering spacious accommodation for four to six guests. She includes three generous staterooms, a bright saloon and a well-appointed galley designed for serious cooking, with the option to fit full-size appliances.

Outdoor living is equally well considered. The aft cockpit is ideal for entertaining, with space for al fresco dining, lounging or fishing. The flybridge delivers sweeping views and can be configured to suit your needs, from relaxing and sunbathing to additional storage or even a premium guest berth.

Beneath her sleek exterior lies a large-volume displacement hull, optimised for efficient passage making, stability and comfort at sea. Whether exploring nearby islands or undertaking longer bluewater voyages, Iona delivers a cruising experience that is refined, capable and economical.

With her semi-custom build already underway, Iona offers a rare chance to create a yacht that is truly your own, built for adventure, crafted for comfort and designed to stand out.
