Performance Expectations, based on the Design Ratios
The Sirius 40 DS is a moderate displacement cruiser, which means she can carry all your cruising gear without compromising her speed and agility. She has a displacement/length ratio of 232, which is typical for most offshore cruising boats today. She also has a sail area/displacement ratio of 16.2, which indicates that she has enough sail power to perform well in light to moderate winds. Her ballast/displacement ratio of 30% ensures that she has a good stability and righting moment in case of a knockdown.
Production Period and Numbers Produced
The Sirius 40 DS was launched in 2018 as the flagship model of the Sirius Yachts range. She is the successor of the Sirius 35 DS, which was introduced in 2013. The Sirius Yachts company was founded in 1971 by Peter Schmidt in Germany and is now run by his son Torsten Schmidt. The company specializes in building deck saloon yachts with custom interiors and various keel options.
The Sirius 40 DS is a semi-custom boat, which means that each yacht is built according to the specific requirements and preferences of the owner. Therefore, there is no fixed number of boats produced per year or in total. However, according to the company website, there are currently more than 20 Sirius 40 DS yachts sailing around the world.
Alternative Versions & Options
The Sirius 40 DS is available with four different keel configurations: a single fin keel, a lifting keel, or twin keels (either fixed or lifting). The choice of keel depends on your sailing style, your cruising area, and your personal preference. The fin keel offers the best performance and stability, but also the deepest draft. The lifting keel gives you the flexibility to adjust the draft according to the water depth but also adds some weight and complexity to the boat. The twin keels allow you to dry out on tidal flats or beaches, but also reduce the sailing efficiency and increase the wetted surface.
The Sirius 40 DS also offers various interior layouts, from two to six berths, as well as different options for the saloon, galley, navigation station, workshop, storage space, and other features. You can customize your boat to suit your needs and preferences, whether you want more comfort, more functionality, or more luxury. Some examples of unique features that have been requested by owners include a sauna, a piano room, an office room, or a wine cellar.
Number & Location of Sleeping Berths
The Sirius 40 DS can accommodate up to six people in three double cabins, depending on the interior layout chosen by the owner. The standard layout offers a spacious owner's cabin in the bow, with a large island bed, a wardrobe, and an ensuite bathroom. The aft cabin has a double bed, a wardrobe, and a shared bathroom with the saloon. The third cabin is located on the lower level, under the saloon, and can be used as a guest cabin, a workshop, or a storage room.
The saloon can also be converted into an additional double berth by lowering the table and adding cushions. This option is useful for extra guests or for sleeping in the saloon when the weather is too hot or too cold in the cabins.

History of the Boatbuilder
The Sirius Yachts company was founded in 1971 by Peter Schmidt in Germany. He started by building small sailing dinghies and later moved on to larger yachts. In 1980, he introduced the first deck saloon yacht in the world, the Sirius 22 DS. He then developed other models of deck saloon yachts, ranging from 26 ft to 35 ft.
In 2008, Peter Schmidt handed over the management of the company to his son Torsten Schmidt. Torsten Schmidt continued to expand the range of deck saloon yachts, adding new models such as the Sirius 31 DS in 2010 and the Sirius 40 DS in 2018. He also improved the quality and innovation of the boats, using modern materials and technologies.
Today, Sirius Yachts is one of the leading manufacturers of deck saloon yachts in Europe. The company employs about 50 skilled craftsmen.
Secondhand Values
The Sirius 40 DS is a relatively new boat, so there are not many secondhand models available on the market. However, based on the few listings that we found online, the average asking price for a used Sirius 40 DS is around $500,000 USD. This is quite high compared to other similar-sized cruising boats, but it reflects the quality, durability, and uniqueness of the Sirius 40 DS.
