Direct peers

• Regs4Yachts: Regs4Yachts supplies the Digital Maritime Regulations service embedded inside Compass. It is both an integrated partner and a stand-alone competitor for regulatory publication subscriptions within the same superyacht crew customer base.
• Voyager Worldwide (ChartCo / AWT): Voyager Worldwide (incorporating ChartCo and AWT) provides managed chart and publication services to commercial shipping, with parallels to DSNM's chart-and-publication outfit management for superyachts. It is the closest analog in business model: outsourced navigation content management on a subscription basis.
• Imray, Laurie, Norie & Wilson: Imray publishes the cruising guides and charts whose content (13,500+ geo-tagged articles) is bundled into Compass. It is a primary content partner to DSNM and a competing publisher of navigational information in the leisure marine segment.
• TimeZero (MaxSea): TimeZero (formerly MaxSea) offers navigation software with worldwide nautical charts and is supplied by DSNM as part of its digital charting portfolio. It is a directly comparable navigation-software platform competing for the same crew use cases.
• NAVTOR: NAVTOR provides digital maritime charts and the Pay As You Sail service that DSNM distributes to superyachts. It is both a core supplier to DSNM's Compass platform and a competing chart provider serving the same global maritime market, making it the most directly comparable peer.

Broad incumbents

• Raymarine (Teledyne FLIR): Raymarine, part of Teledyne FLIR, provides marine electronics including chartplotters, radar, and AIS that DSNM's outfit management supplies alongside software. It is a broad incumbent in leisure marine navigation hardware with overlapping customer set.
• Sperry Marine (Northrop Grumman): Sperry Marine supplies commercial-grade bridge navigation equipment, gyrocompasses, and integrated bridge systems. While primarily commercial, its product set overlaps with DSNM's outfit-management scope on superyachts equipped with high-end bridge systems.
• Furuno: Furuno is a long-established manufacturer of marine navigation and communication equipment (radar, ECDIS, GNSS). It is a broad incumbent in marine electronics whose bridge systems overlap with the navigation stack that Compass integrates and supports.
• Wärtsilä Voyage (Transas): Wärtsilä Voyage, formed from the Transas acquisition, is a major ECDIS and integrated bridge systems provider in commercial shipping. DSNM supplies and supports Transas TX97 charts, positioning Wärtsilä as both a data partner and the dominant incumbent in the broader marine navigation systems market.
• Garmin (Navionics): Garmin owns the Navionics chart brand, which DSNM bundles for Tender Cards. Garmin is a broad marine electronics incumbent providing navigation plotters, charts, and instruments that overlap with parts of Compass's data offering.
