Description
ONWA KP-27X 7-Inch GPS Chart Plotter 4-in-1 Marine Supplies with Class B+ AIS Tracking and Fish Finder
System Overview & Engineering Architecture
The ONWA KP-27X is a 7-inch GPS Chart Plotter engineered as a 4-in-1 Marine Supplies platform, consolidating multiple marine electronic functions into a single integrated unit. The system architecture combines GPS Chart Plotting, Class B+ AIS Tracking, and Fish Finder capabilities within a unified 7-inch display form factor, designed to support marine navigation and fishing operations from a single bridge-mounted instrument.
As a GPS Chart Plotter, the KP-27X provides core vessel positioning and route management functionality. The unit receives GPS satellite signals to determine vessel location and overlays this position on electronic navigational charts, enabling mariners to monitor progress, plan routes, and maintain accurate navigation awareness. Chart plotter functionality is a foundational element of modern marine navigation, and the KP-27X integrates this capability as its primary operational mode.
The 4-in-1 design philosophy of the ONWA KP-27X reflects a consolidated approach to marine electronics integration. By combining GPS Chart Plotting, AIS Tracking, Fish Finding, and chart plotter navigation into a single unit, the system reduces the number of discrete instruments required on the bridge. This integration approach supports streamlined equipment management, reduced cabling complexity, and a more organized bridge layout.
The 7-inch display serves as the primary user interface for all four integrated functions. The display dimensions are selected to provide adequate screen real estate for chart visualization, AIS target lists, and fish finder sonar returns while maintaining a compact footprint suitable for marine console and helm installation. The display format supports simultaneous or switchable views across the integrated functions, allowing the operator to access GPS positioning, AIS surveillance, and sonar data as operational requirements demand.
The ONWA KP-27X is positioned as a multi-function marine navigation instrument suitable for a range of vessel types and operating profiles. Its 4-in-1 configuration makes it a versatile platform for operators seeking consolidated navigation and fishing electronics without deploying multiple standalone instruments.
Core Features & Operational Advantages
GPS Chart Plotter Functionality
The GPS Chart Plotter function forms the core navigation capability of the ONWA KP-27X. The system processes GPS satellite data to determine vessel position and displays this information over electronic navigational charts. Chart plotter functions include position tracking, route waypoint programming, route guidance, and cross-track error monitoring. These capabilities support safe navigation by providing the operator with continuous awareness of vessel position relative to planned routes and charted hazards.
The chart plotter function of the KP-27X is designed to integrate with standard marine navigation workflows. Operators can input waypoints, define routes, and monitor navigation progress through the 7-inch display interface. The GPS Chart Plotter function is essential for coastal navigation, port approaches, and open-water transit where electronic position reference is critical to safe passage.
Class B+ AIS Tracking
The ONWA KP-27X incorporates Class B+ AIS Tracking as one of its integrated functions. Class B+ AIS is an enhanced classification within the Automatic Identification System framework, offering improved data reporting intervals and extended vessel information compared to standard Class B AIS. The KP-27X receives AIS transponder signals from nearby vessels and displays AIS target data on the chart plotter overlay, enhancing situational awareness in busy waterways, port approaches, and coastal navigation zones.
Class B+ AIS functionality supports collision avoidance and traffic awareness by providing the operator with real-time information on surrounding vessel positions, identities, courses, and speeds. This capability is particularly valuable in high-traffic areas and during periods of reduced visibility. The integration of AIS tracking within the GPS Chart Plotter display allows the operator to correlate AIS target data with charted navigation hazards and planned routes on a single screen.
AIS systems such as the ONWA KP-27X complement broader bridge instrumentation arrangements. For operators managing larger vessels with dedicated Class A AIS installations, the KP-27X Class B+ AIS function provides supplementary vessel traffic awareness. For further information on AIS system specifications and class approvals, refer to the SAILOR 6280 AIS System Class A JNPA and SAAB R6 Supreme AIS Class A JNPA product pages.
Fish Finder Integration
The Fish Finder function integrated into the ONWA KP-27X provides sonar-based underwater detection capability. The fish finder transmits acoustic signals and processes returning echoes to display underwater structures, fish schools, and seabed characteristics on the 7-inch display. This function extends the operational utility of the KP-27X beyond pure navigation into fishing and underwater survey applications.
The fish finder integration allows the same unit to serve dual navigation and fishing purposes, eliminating the need for a dedicated standalone fish finder in applications where both functions are required. The sonar display can be accessed alongside or independently from the chart plotter and AIS views, providing operational flexibility.
7-Inch Display Platform
The 7-inch display is the central interface for all ONWA KP-27X functions. The display size is engineered to provide sufficient viewing area for chart plots, AIS target lists, and fish finder sonar returns while maintaining a compact installation profile. The 7-inch format is suitable for helm consoles, bridge wings, and navigation station mounts where space is a consideration but readability remains essential.

SOLAS, IMO, IEC & Classification Society Compliance
The ONWA KP-27X incorporates Class B+ AIS Tracking functionality, which is recognized within the IMO framework as a standard for vessel identification and tracking. The IMO has established AIS performance standards under Resolution A.857(20) and related amendments, defining operational requirements for AIS equipment deployed on vessels subject to the International Convention for the Safety of Life at Sea (SOLAS).
Class B+ AIS is designed for vessels that are not required to carry Class A AIS under SOLAS Chapter V, but which benefit from enhanced AIS surveillance capabilities. The KP-27X Class B+ AIS function supports vessel traffic monitoring and collision avoidance in accordance with the IMO’s broader framework for maritime safety and navigation.
Specific SOLAS, IMO, IEC, and classification society approvals applicable to the ONWA KP-27X should be verified with the equipment manufacturer and the relevant flag state authority. Classification societies including DNV, ABS, and Lloyd’s Register maintain specific requirements for marine electronic equipment based on vessel type, tonnage, and operating area.
