With an average length of 110.9 meters and an impressive average volume of 5,295 GT, these vessels redefine what it means to rule the seas. From groundbreaking designs to cutting-edge, environmentally friendly hydrogen-powered technology, this year’s fleet showcases the pinnacle of modern yacht building.
Why Gross Tonnage Matters More Than Length
While length has traditionally been the go-to metric for comparing the world's largest yachts, the industry is increasingly recognizing Gross Tonnage (GT) as a more accurate and meaningful measurement. Unlike length, which only tells part of the story, GT accounts for a yacht's interior volume—a critical factor in understanding the space, luxury, and functionality offered by these floating palaces.
Modern yacht design often prioritizes interior innovation and spaciousness over sheer length, making GT a more comprehensive benchmark which is why we created the Yachtbuyer YB100 - A True Measure of the World's Biggest Yachts . More volume allows for the inclusion of an impressive array of amenities that transform these yachts into floating luxury resorts.
Unusual Design Requests: Redefining Onboard Amenities
The extra volume found in modern superyachts has paved the way for some of the most extravagant and unexpected design requests from owners. Here are a few of the most bizarre and ambitious additions that have been incorporated into recent builds:
- Submarine Garages – Custom spaces to house personal submarines for underwater exploration.
- Onboard Nightclubs – Fully-equipped dance floors, DJ booths, and lighting systems for hosting exclusive parties at sea.
- Glass-Bottom Pools – Suspended pools with see-through floors, offering stunning views of the ocean below.
- IMAX Theaters – Private cinemas featuring the latest in screen and sound technology.
- Snow Rooms – Climate-controlled rooms filled with real snow, perfect for cooling off after a session in the sauna.
- Full-Size Indoor Paddle Courts – Spaces dedicated to the growing sport of paddle tennis, allowing owners and guests to play regardless of weather conditions.
- Personal Zoos – Dedicated spaces for exotic pets, including aviaries, aquariums, and even miniature habitats for animals.
- Hydroponic Farms – Onboard gardens to grow fresh vegetables, herbs, and flowers for the ultimate farm-to-table dining experience.
- Holographic Entertainment Systems – High-tech projections for immersive gaming and entertainment.
These requests highlight the limitless imagination of yacht owners and the incredible versatility afforded by higher Gross Tonnage. As the boundaries of yacht design continue to expand, it’s clear that the superyachts of 2025 will be unlike anything we’ve seen before.

This impressive yacht measures over 110m (360ft) in length, spans five decks, and is supported by a substantial 17.5m (57ft) beam.

These design elements, often seen in commercial vessels, allow the yacht to slice through waves, reducing noise, and vibration, and improving fuel efficiency in rough seas. This also makes ICECAP ideal for long-range cruising.

The decks are mostly enclosed or shaded, catering to various climates, with multiple outdoor lounges and observation areas for open-air enjoyment.
