About Heesen 50M Aluminium Yn 21150 Project Sophia
A CURVY, SPORTY EXTERIOR DESIGN. At 50 metres and below 500 GT, Sophia is an all-aluminium, fast-cruising yacht powered by green ocean engines. Heesen’s 50-metre fast-cruising class is the first of its kind below 500 GT to comply with IMO Tier-III regulations. A curvy, sporty exterior design by Omega Architects complements Sophia’s performance and crisp design features. Heesen’s optimised, low-drag hull design with a reduced transom depth allows for a shallow shaft angle. This makes Sophia comfortable in rough seas yet perfect for cruising shallow waters. The ultra-efficient hull shape delivers on engineering and adventure, meaning Sophia is ideal for both island hopping and longer passages.

A Curvy, Sporty Exterior Design.
- At 50 metres and below 500 GT, Sophia is an all-aluminium, fast-cruising yacht powered by green ocean engines. Heesen’s 50-metre fast-cruising class is the first of its kind below 500 GT to comply with IMO Tier-III regulations. A curvy, sporty exterior design by Omega Architects complements Sophia’s performance and crisp design features.
- Heesen’s optimised, low-drag hull design with a reduced transom depth allows for a shallow shaft angle. This makes Sophia comfortable in rough seas yet perfect for cruising shallow waters. The ultra-efficient hull shape delivers on engineering and adventure, meaning Sophia is ideal for both island hopping and longer passages.
First Impressions.
- Sophia is the fourth sister in this impressive class. Its elevated aft deck holds a large whirlpool with sunpads, which is accessed via three steps up. It’s this subtle design feature that allows for a full height multi-purpose tender garage-cum-luxury beach club on the lower deck, with plenty of head room. Another key exterior feature is the downward pointing bow. This provides a good line of sight to the water from the bridge, and helps to accentuate Sophia's long, sleek profile.
- “The whole superstructure is slightly curved giving her a more elegant aft end, while the use of wrap around glass and loose exterior furniture mean deck spaces have generous seating, but remain airy, light and well detailed,” explains Laupman.
Step Aboard.
- A sophisticated interior by acclaimed Italian designer Cristiano Gatto welcomes twelve guests in five staterooms.
- The master suite, on the main deck forward, is bright and airy. The spacious remaining suites are found down on the lower deck. Sophia also offers plenty of outdoor areas for her owners, family, and friends to enjoy life at sea. The beach club will bring them close to the on-water action, while the generous sun pad area on the main deck terrace is perfect for post-swim relaxation. Al-fresco dining can take place either on the bridge deck aft terrace or up on the spacious sundeck.
