What Pro Nautik AG does

Pro Nautik AG is a 40-year-old Swiss boat dealership and full-service shipyard headquartered in Romanshorn on Lake Constance, with a second yard opened in Arbon in 2025. The company operates as an authorized dealer for nine premium boat brands spanning motorboats, sailing yachts, hybrid/electric propulsion, and wake/surf boats (Bavaria, Greenline, Jeanneau, Malibu, Axis, Regal, Sunbeam, Boesch, Airon Marine), and it manufactures the Füllemann sport-fishing line through an acquired brand. Its services cover the full ownership lifecycle: new and used boat sales (via showrooms, boat shows, and an online Boatfinder), a 36-month all-inclusive Boot-Abo subscription, winter storage, summer services, Park & Ride launching, engine service (including O.CT Marine outboards), electronics installation, custom modifications, certified Quagga mussel cleaning for inter-lake transfers, and an AI-enabled 24/7-monitored boat security/alarm service.

The company generates revenue from three layered streams: one-time transactions (new and used boat sales, parts and accessories across a 10,000+ SKU warehouse), recurring contracts (Boot-Abo subscriptions, winter storage, berth rentals via the Boatpark app), and professional services (maintenance, repair, Park & Ride crane operations, Quagga cleaning charged at CHF 130–148/hour). Distribution combines direct showroom sales at two Lake Constance locations, participation in major industry shows (boot Düsseldorf, Interboot Friedrichshafen), an in-house annual customer event (Knotenpunkt), and a partner network extending service coverage to Lake Zurich, Lucerne, Neuchâtel, Biel, and Thun.

The company's most operationally significant capability is hybrid and electric boat expertise, with approximately 80 Greenline and comparable hybrid vessels sold and serviced — a working knowledge base that supports the AI security service (intelligent video analytics with 24/7 Swiss monitoring), the certified Quagga cleaning capability (regulatory compliance for water-body transfers), and Lobster-style custom boat builds combining CAD planning with CNC milling. Ownership is private and family-linked, with an executive board comprising Yves Bosshart and Michael Gallusser (sales), Barbara Bosshart (HR), and Susanne Rüesch (finance). NAUTIKA, the boat school subsidiary acquired in 2021, extends the platform into training, charter, and licensing.

Expansion highlights6 records

Regional players

• Bootswerft Burmester GmbH: Established German boat yard offering new-boat sales, refits, winter storage and engine service. Comparable full-service yard model but based in northern Germany rather than competing head-to-head at Lake Constance.
• Yachtwerft Berlin GmbH: Berlin-area boat yard providing sales, service and winter storage for motor and sailing yachts. Comparable service-yard business model and customer type (private owners), but located in a different German region.

Broad incumbents

• Greenline Yachts: Hybrid and electric yacht manufacturer whose Swiss dealer is Pro Nautik. Comparable as the upstream OEM defining the electric/hybrid category that anchors Pro Nautik's specialty positioning.
• Bavaria Yachts GmbH: One of the largest European serial yacht builders and Pro Nautik's flagship brand partner. Comparable only at the OEM level — Bavaria sets wholesale terms, model availability and dealer network strategy that directly shape Pro Nautik's economics.

Direct peers

• Wacker Boote GmbH: Boat dealer and service yard on Lake Constance with multi-brand representation, brokerage, winter storage and workshop services. Operates on the German side of the same lake — same geography and category, slightly different customer base.
• Boesch Motorboote AG: Swiss manufacturer of exclusive wooden motorboats (since 1910) — both a brand Pro Nautik sells and an adjacent Swiss luxury boat brand. Overlaps in customer base, geography and Lake Constance heritage.
• Hausammann Boote AG: Founding company of Pro Nautik and still operating a parallel showroom in Uttwil plus the online parts shop. Closest analog: family-led Swiss boat dealer with overlapping premium-brand portfolio and direct customer overlap.
• Marina Chrischorn AG: Full-service marina and boat yard directly across Lake Constance from Pro Nautik, offering berths, winter storage, service and brokerage. Highly comparable as the closest competing Swiss shipyard on the same body of water.
• Boot- und Yachtcenter Bodensee: Multi-brand boat dealer and full-service yard on Lake Constance. Comparable in scale, brand mix (motor and sailing) and year-round service offering to Pro Nautik's two Swiss yards.

Others

• Interboot Friedrichshafen: Annual water-sports trade show at Friedrichshafen where Pro Nautik is a regular exhibitor. Comparable only as an ecosystem enabler shaping how Swiss and German yards reach retail boat buyers.
