Transform your device into a professional radar simulator and collision avoidance training tool. CASim is designed for maritime cadets, deck officers, and navigation enthusiasts who want to master the International Regulations for Preventing Collisions at Sea (COLREGs) through practical application. Bridge the gap between theory and reality. Practice identifying risks on the radar scope, correlating them with visual aspects, and executing the correct maneuvering actions. Key Features: - Realistic Radar Simulator: Experience a fully functional Head-Up radar scope complete with variable range scales, target trails (history), and relative motion vectors. - Tactical Plotting (MoBoard): Integrated digital Maneuvering Board. Plot targets manually or automatically to calculate CPA (Closest Point of Approach), TCPA, and determine the precise course to steer to avoid collisions. - Visual Aspect Visualization: See what the target ship looks like in reality. The app generates 3D models with correct Navigation Lights (Night) and Day Shapes based on the targetβs aspect angle. - Restricted Visibility Mode: Simulate fog conditions (Rule 19). Test your ability to navigate using only radar and sound signals. - Sound Signals: Authentic fog signals (Rule 35) are generated automatically based on the vessel type and status (Underway, Stopped, NUC, Anchored, etc.). - Custom Scenarios: Create your own traffic situations with multiple targets, varying speeds, and ship types to challenge your skills. Whether you are preparing for your competency exams or refreshing your skills, CASim provides the most comprehensive simulation environment right in your pocket.
