11m ORC - Wheelhouse

This craft is a further development of our ORC series using the 11m ORC hull form and proven engineering technology with an enclosed walk-around wheelhouse arrangement.

The vessel adopts the same design approach to that of the rest of the ORC series, offering a low cost platform with great flexibility. This flexibility means that the arrangement can be specifically tailored to meet clients requirements with a number or propulsion packages available including waterjet, sterndrives and multiple outboard motors. The forward and aft weapon pedestals are capable of mounting either a twin GPMG or a single HMG with the aft pedestal also doubling up as a heavy duty towing bollard.

Like the rest of the ORC series the vessel has been designed for optimum maintenance and future proofing ensuring a vessel that is simple and economical to maintain. Crew safety and comfort has been a focus, the high topsides, walk-around air-conditioned wheelhouse and an option for a small WC ensures a safe secure and comfortable working environment.
