CA'Sim

Master the Rules of the Road. Anytime, Anywhere.

CA'Sim (Collision Avoidance Simulator) is a professional-grade training tool designed for mariners, deck officers, and cadets. Practice radar plotting, assess collision risks, and visualize vessel aspects based on COLREGs rules, all from your smartphone or tablet.

Key Features

• Realistic Radar Simulator: Experience a fully functional radar scope with vectors, and trails. Simulate realistic environmental conditions like restricted visibility (fog).
• Advanced Tactical Plotting (Maneuvering Board): Integrated digital MoBoard allows you to plot target positions (M1, M2, M3) and construct the e-r-m vector triangle to solve for target's true course, speed, and relative motion (DRM/SRM).
• Trial Prediction Mode: Plan your maneuvers with confidence. Adjust your own ship's Course (CRS) and Speed (SPD) in trial mode to instantly see how the CPA and TCPA will change before making an actual turn.
• Motion Analysis: Get precise calculations for CPA, TCPA, and Target True data (CRS/SPD) to ensure compliance with COLREGs.
• Visual Aspect Viewer: Bridge the gap between radar and visual observation. View 3D models of target vessels.
• Navigation Lights & Day Shapes: Realistic representation based on the target's aspect angle.
• Scenario Builder: Create custom training scenarios with multiple target ships and various vessel types.

Perfect For

• Maritime Cadets and Students
• Deck Officers preparing for competency exams
• Navigation enthusiasts
