The right size for safety and comfort
The size of a sailboat plays an essential role in the success of a round-the-world voyage. Above all, safety is a major criterion. A larger sailboat offers better handling at sea, especially in difficult weather conditions. The longer the boat, the more stable it is to cope with waves and winds, reducing the risk of capsizing or crew discomfort. But this extra length also requires more effort for maneuvering and managing large sail areas. The price will also play a role in the length of the boat: the longer it is, the higher the price.
Comfort for life on board is also crucial, especially depending on the composition of the crew. For a long cruise, interior space must be designed to offer a real quality of life. Cabins must allow for a restful rest, the galley must be functional and the stowage well designed to store provisions, navigation equipment and personal belongings. A well-sized sailboat can also accommodate essential equipment for self-sufficiency at sea, such as a watermaker, solar panels and large-capacity water and fuel tanks.
If you're looking for a minimalist experience and your budget is limited, a 35- to 40-foot sailboat will give you plenty of adventure. For comfortable family cruising, a 40 to 50-foot boat is the perfect compromise. Finally, if you aspire to high-end cruising with all the comforts of home, yachts over 50 feet will offer you an incomparable experience.

The 35- to 40-foot sailboat, the minimum for adventure
For a round-the-world trip, the minimum recommended size is generally between 35 and 40 feet (approx. 10 to 12 m). This type of yacht offers good maneuverability, even with a reduced crew, and is ideal for a couple or small family.
Here are a few models sufficiently equipped for long crossings, even if their storage space remains limited. A good compromise for sailors on a tight budget.
- Jeanneau Sun Odyssey 36i - 11 m a versatile, sturdy model, appreciated for its ease of navigation and comfortable interior.
- Dufour 382 Grand Large - 11,25 m a spacious family sailboat for its size, ideal for extended cruising.
- UFO 365 Alubat - 11,94 m made of aluminum, it is particularly appreciated for its sturdiness and its ability to tackle remote anchorages thanks to its centerboard.

Sailboats between 40 and 50 feet, a compromise between performance and comfort
Sailboats from 40 to 50 feet (12 to 15 meters) are often considered the ideal choice for those seeking a balance between comfort, safety and autonomy. This size allows you to carry more equipment and offers a more generous living space.
Here are 3 models in this category for more comfortable long crossings and more relaxed anchorages thanks to the extra space:
- Hallberg-Rassy 44 - 13,41 m a Scandinavian sailboat renowned for its solidity, on-board comfort and ability to handle the high seas.
- Bavaria C45 - 13,98 m a modern, spacious yacht, perfect for families or those who want to combine performance and habitability.
- Amel 50 - 16,50 m a top-of-the-range model, highly appreciated for its cruising-oriented design and comprehensive standard equipment.

Units over 50 feet for more luxury
For those seeking maximum comfort, sailing yachts over 50 feet (15 m and more) represent a veritable floating home. These units are perfectly suited to major expeditions, offering exceptional living space and a high degree of autonomy. These yachts are ideal for large families or those wishing to sail with a crew. They do, however, require solid sailing experience and substantial financial resources, both for purchase and maintenance.
Take a look at some examples of sailing yachts over 50 feet:
- Garcia Exploration 52 - 16,65 m a model designed for adventure, able to navigate in the most remote areas thanks to its aluminum hull and reinforced autonomy.
- Beneteau Oceanis 55.1 - 16.78 m a spacious, modern yacht, ideal for those seeking a blend of performance and comfort.
- Oyster 565 - 18,09 m a luxury yacht renowned for its top-of-the-range finish, exceptional comfort and performance on the high seas.

Monohull or catamaran, which model to choose?
Choosing the right size also depends on the type of sailboat you are planning . Monohulls are generally shorter than multihulls. Monohulls are generally more affordable. Catamarans, on the other hand, appeal to those seeking comfort above all else. With its two hulls, it offers great stability at anchor and impressive living space. Beware, however, that under 40 feet in length, a catamaran can be dangerous in rough seas, with a risk of rocking. They are also more expensive, and can pose difficulties in certain marinas due to their width.
