What A+T Instruments does

A+T Instruments (legal entity AT Instruments Ltd) is a privately held UK marine electronics company founded in 2015 in Lymington by Richard Tinley and Hugh Agnew. It designs and manufactures processors, displays, wind sensors, and accessories for superyachts and high-performance raceboats, with full backward compatibility to legacy B&G 213, H2000, H3000, and H5000 systems. Its core technology stack is an Ethernet-based instrument architecture centered on ATP/ATPX processors running at 50Hz with built-in heel/pitch sensing, A+T 500 Series wind sensors calibrated to 0.2 degrees, and the Big Format Display (BFD) and HFD5 displays tested to IPX7 at 1 metre for 24 hours. A+T holds sole-worldwide manufacturing rights for bronze gate shut-off valves used to swap speed and depth sensors on superyachts.

The company operates a sales-led, enterprise-focused go-to-market combining a UK-based direct sales team, a Palma de Mallorca sales office covering the Mediterranean, certified installation partners (Osprey Technical Consulting, Tijssen), and a worldwide e-commerce spare-parts shop. Revenue is generated through one-time hardware sales of new systems, spares, and component-level electronic repairs (inherited from predecessor Tinley Electronics). Pricing is in GBP ex-VAT, with notable items ranging from GBP 50 (suncovers) to GBP 3,804 (shut-off valves), and complete systems commonly reaching GBP 50K-150K per yacht. A+T reported 40% year-on-year growth over the three years to 2025, has equipped more than 800 yachts cumulatively, and added commercial-shipping and Mediterranean-sales expansion in 2024 ahead of new H5000 replacement-display launches slated for 2026.

Broad incumbents

• Furuno: Furuno is a broad marine electronics incumbent specializing in radar, navigation, and integrated bridge systems. Furuno has a mutual integration partnership with A+T for TimeZero Professional software and glass bridge manufacturers, serving overlapping superyacht and commercial customers.
• Raymarine (FLIR Systems): Raymarine is a broad marine electronics incumbent offering multifunction displays, instruments, radar, and navigation systems for sailing and powerboats. Raymarine Axiom displays integrate with A+T wind sensors (per Balize 526 case) and compete in the larger marine electronics market with much broader scale.
• Garmin Marine: Garmin is the largest marine electronics brand by revenue, offering GPSMAP chartplotters, instruments, and integrated marine systems. Garmin displays are supported by A+T through CANbus interfacing and serve overlapping sail and powerboat markets, albeit at a more mass-market positioning than A+T's superyacht niche.
• Simrad (Navico / Brunswick): Simrad is a sister brand to B&G under Navico (owned by Brunswick), offering multifunction displays and instrument systems for sail and power boats. Simrad overlaps with A+T in sailing instrument functionality and represents a broader-market alternative for yachts that don't require superyacht-grade performance.

Direct peers

• B&G (Navico / Brunswick): B&G is the legacy incumbent whose 213, H2000, H3000, and H5000 systems A+T directly replaces, upgrades, and supplies spares for. B&G dominates the sailing instrument market with vertically integrated displays, processors, and sensors - making it the closest direct competitor and the source of A+T's upgrade opportunity.
• NKE Marine Electronics: NKE is a French manufacturer of high-performance sailing instruments for racing yachts and superyachts, offering processors, displays, and sensors with similar positioning to A+T. NKE competes head-to-head in TP52, Class 40, Mini Transat, and ocean racing segments where both companies supply wind sensors and instrument systems.
• FaRo Advanced Systems: FaRo is a partner/competitor in high-end racing instrument processors, with its FaRo race processor driving A+T's BFD displays on vessels like Swan 125 Skorpios. FaRo specializes in performance navigation processors for top racing campaigns, overlapping with A+T's ATPX processor positioning.

Others

• Orolia (McMurdo): Orolia, through its McMurdo brand, is a global leader in maritime distress beacons, EPIRBs, and safety electronics. McMurdo serves overlapping superyacht and offshore racing customers requiring safety and navigation equipment, sitting adjacent to A+T's wind and instrument focus.
• KVH Industries: KVH provides marine satellite communications, navigation sensors, and inertial measurement units used on commercial and leisure vessels. KVH's IMU technology overlaps with A+T's inertial wind sensor development and addresses a similar high-end customer base requiring precision motion sensing.

Emerging players

• Sailmon: Sailmon is a Dutch startup offering modern sailing instrument systems with app-based displays and data analytics aimed at performance sailing. Sailmon targets similar racing and performance sailing customers as A+T but with a more software/cloud-centric approach, representing an emerging alternative.
