Marsili

What Marsili does

Marsili Aldo & C. S.R.L. is an Italian manufacturer of hydraulic, electro-hydraulic, and electronic steering systems for marine vessels ranging from 5 to over 90 metres. Founded in 1957 in Civitanova Marche and operated by the founding family through three generations, the company designs and produces a complete steering chain — electro-hydraulic power packs, hydraulic cylinders, remote controls, helm pumps, and synchronization valves — plus trim tabs and attitude correctors through its Seipem Technology sub-brand, acquired in 2012. The catalogue spans over 600 references and is organized around four system architectures: Type A (pure hydraulic), Type B (electro-hydraulic), Type F/G (servo-assisted with orbitrol or feedback), and Type H/I (full-electric), enabling coverage from small outboard craft to superyachts and naval vessels.

The business model is B2B enterprise sales into shipyards, naval/military contractors, and yacht builders, supplemented by technical support, spare parts, and after-sales. Pricing is quote-based, derived from vessel specifications and project complexity rather than published list rates, with a 24-working-hour technical response commitment from the in-house engineering team. Distribution is executed through a network of 45 qualified distributors across 30 countries on five continents, complemented by direct enterprise engagement via METS Amsterdam and other trade channels. The company holds RINA, ABS, Russian Maritime Register, and Russian River Register certifications, and its reference list includes FINCANTIERI, Intermarine, Perini Navi, C.R.N. (Ferretti Group), Gulf Craft, and the Italian Guardia di Finanza. Revenue is not publicly disclosed and the company is privately held with no external institutional investment identified.

Direct peers

• Jastram: Jastram is a German manufacturer of hydraulic and electro-hydraulic marine steering systems for commercial and naval vessels. It is the most direct competitor to Marsili, offering a similar product mix of helm pumps, cylinders, power packs, and rudder actuators for ships and boats.
• Scan Steering (Bosch Rexroth): Scan Steering, originally a Swedish marine steering specialist, was acquired by Bosch Rexroth. It competes directly with Marsili in hydraulic steering systems for commercial and leisure marine segments, with the added backing of a large industrial hydraulics group.
• Kobelt Manufacturing: Kobelt is a Canadian manufacturer of marine steering controls, hydraulic actuators, and remote-control systems. It overlaps with Marsili's helm pumps, remote controls, and electro-hydraulic power pack offerings, serving similar commercial and workboat customers.
• Hy-Pro: Hy-Pro (UK) designs and manufactures hydraulic steering systems, helm pumps, and cylinders for marine applications. It targets a comparable niche of yacht, commercial, and small-vessel customers, directly competing with Marsili's Type A hydraulic and outboard steering kit lines.

Broad incumbents

• ZF Marine: ZF Marine is a division of ZF Friedrichshafen supplying marine transmissions, steering systems, and propulsion components globally. As a broad incumbent, ZF offers steering alongside driveline products, competing with Marsili where shipyards want integrated propulsion and steering packages.
• Lewmar: Lewmar is a UK-based supplier of marine deck hardware, winches, anchors, and steering systems for yachts. It overlaps with Marsili in steering wheels, hydraulic steering kits, and yacht controls but operates a broader portfolio of marine equipment for OEMs and aftermarket.
• Sperry Marine (Northrop Grumman): Sperry Marine, part of Northrop Grumman, supplies integrated bridge systems including autopilots and steering controls for naval and commercial vessels. It is a broader incumbent that competes where shipyards procure integrated navigation and steering suites rather than standalone hydraulic systems.
• Twin Disc: Twin Disc manufactures marine power transmission systems, controls, and integrated steering solutions for commercial and military vessels. It is comparable as a broader marine systems supplier whose control product range overlaps with Marsili's remote-control and electro-hydraulic offerings.

Emerging players

• Sleipner Motor: Sleipner Motor (Norway) produces bow and stern thrusters and related onboard control systems for yachts. While primarily thruster-focused, its electronic control interfaces overlap with Marsili's Type H/I electronic steering and remote control product lines in the recreational and mid-size yacht segment.
• Glendinning Marine: Glendinning Marine Controls (US) manufactures marine engine and steering controls, including electronic remote controls and synchronizers. Its product range directly overlaps with Marsili's remote controls, FFU transmitters, and joystick/tiller systems for yachts and small commercial vessels.
