Italian boatbuilder Stem Marine, long respected for their robust SAR (search and rescue) and firefighting vessels, is turning the tide with their first-ever sailing yacht, the Stem 50. Measuring an impressive 52 feet (around 16 meters), this aluminium cruiser will make its world premiere at the 2025 Genoa International Boat Show from September 18 to 23, 2025. This marks a bold step into the leisure sailing market, but with a safety-first DNA deeply rooted in Stem Marine’s professional maritime background.

Aluminium is not merely a trendy option here, it is a serious one. Because of its longevity and corrosion resistance, aluminium is increasingly a material of choice for serious bluewater cruising yachts. The hull and deck of the Stem 50 are entirely built from aluminium, which provides a sense of both durability and a definitive modern element.
It boasts crash boxes at the bow and stern, twin rudders, and a centreboard with a torpedo keel, both of which are intended to instill confidence while sailing offshore. There's also a fixed dodger and a bimini with solar panels for protection, abundant handrails and excellent deck ergonomics to support the shipyard's mindset of "Easy Sailing."
“For the development of the Stem 50, we brought together many clever minds from the sailing and boatbuilding world,” explains Michele Corradi, Managing Director of Stem Marine and a passionate sailor.
This is more than a marketing pitch, Corrad's aspirations surely seem to prioritise safety and livability. The selection of partners, along with French designer Nicolas Purnu (previously working with Marc Lombard's studio) and experienced sailor Luca Sabiu (for overseas sailing in safety), gives the boat the gravitas of any serious sailing yacht.
Inside, the Stem 50 delivers a snug, highly customisable experience. Future owners will be able to personalise all of the layouts and materials for their style, from Scandinavian minimal to classic warmth in truly maritime style. Full energy autonomy has been a primary consideration in the Stem 50: with lithium (LiFePO₄) banks, bi-inverters and excess solar, you will be able to go incredibly far from the marina, still connected to comfort.
Stem Marine even ditched traditional helm wheels in favour of simplified steering controls, a nod to easy handling for short-handed or family crews.
Stem Marine's foray into the sailing yacht market could disrupt this market. The Stem 50 makes a solid case for any sailor wanting to go offshore sailing for a while with minimal effort. The Stem 50 considers a rugged aluminium hull, great design, and minimum fuss on safety.
This move is also part of a wider trend toward lightweight, sustainable, and adventure-ready boats.
