Cox Marine Commissioned New 12-Metre Testing Workboat
The vessel serves as a mobile platform for manufacturers to conduct sea trials and customer product demonstrations.
Updated on Oct. 6, 2026 in Remote Work
Cox Marine has commissioned a 12-metre workboat named Miranda to serve as a testing and training platform. Built by Tideman Marine, the vessel integrates specialized propulsion and navigation systems.
Why it matters
The vessel functions as a dedicated testing ground for engineering validation and customer demonstrations. It allows marine operators to evaluate new propulsion technologies and control systems in real-world sea conditions.
The Miranda features an overall length of 11.95 metres, a beam of 3.40 metres, and a shallow draught of 0.5 metres. It is powered by twin 300hp (220kW) V8 diesel outboard engines.
The players
Cox Marine
An innovator in high-performance marine propulsion systems known for diesel outboard engine development.
Tideman Marine
A specialist shipbuilder focused on the construction of high-density polyethylene workboats for commercial use.
The details
The workboat utilizes a high-density polyethylene (HDPE) hull and integrates advanced electronic steering, joystick control, and autopilot systems. Designed with an enclosed wheelhouse and a broad working deck, the vessel provides a stable environment for engineering validation and sea trials. These technologies enable precise maneuverability during intensive training and demonstration sessions.

Market Landscape
The deployment of the Miranda reflects a growing industry trend of using custom-built testbeds to validate high-performance diesel outboards. This vessel follows patterns set by specialized trials for marine engine reliability and control integration.
Operators should monitor the performance results from this testing platform to gauge the reliability of twin V8 diesel outboard configurations. Businesses managing fleets with similar shallow-draught requirements should track these sea trial outcomes for potential future procurement decisions.
The takeaway
The Miranda emphasizes the importance of field validation when integrating complex propulsion systems like joystick control and autopilot. Future fleet upgrades should consider the vessel's performance data as a benchmark for maneuverability and power density.
