Engineered for Extremes. Trusted by Professionals.
The Roto-Tech Kontra R450CC is a high-performance, 4.5-metre central-console rescue boat purpose-built for the most demanding emergency service operations. Combining the structural stability of a rigid inflatable boat (RIB) with the indestructible nature of polyethylene (LDPE), the R450CC delivers maximum safety, immense payload capacity, and zero-maintenance longevity.
Whether executing urban search and rescue, flood response, or coastal patrols, this craft provides volunteer and professional crews with an unsinkable, puncture-proof platform that performs flawlessly where traditional inflatables fear to tread. A fine swept deep vee bow keeps cuts through chop, keeping those onboard dry and allowing speed to be maintained, where as the stern has a shallower vee, providing great stability whilst extracting casualties whilst at rest.
Battle-Tested on the Front Lines
The Kontra R450 series is relied upon globally by fire brigades, police forces, military divisions, and water rescue teams like the WOPR (Volunteer Water Rescue Service).
- Proven in Storm Boris: When catastrophic flooding from Storm Boris swept through Central Europe, Kontra rescue craft were deployed on the front lines by WOPR teams. Navigating treacherous urban torrents, submerged debris, and violent currents, the boats proved their extreme impact resistance and stability, evacuating citizens safely from areas where sharp underwater hazards would instantly destroy inflatable craft.
- The First Choice for Southampton Independent Lifeboat: Specialist Small Craft proudly customized and delivered a high-specification Roto-Tech R450CC to the newly formed Southampton Independent Lifeboat (SILB) service. Stationed beneath the Itchen Bridge at the Southampton Water Activities Centre (SWAC), the vessel is tasked with rapid-response urban search and rescue across upper Southampton Water and the Test and Itchen rivers.

Key Operational Advantages
- Indestructible Polyethylene Hull: Built from impact-resistant, UV-stabilised, and fully recyclable polyethylene, the hull easily shrugs off strikes from rocks, submerged wreckage, and concrete structures. It requires absolutely no painting or complex maintenance.
- Virtually Unsinkable Design: Buoyancy running right through the hull guarantees structural integrity and floatation even if the outer layer is severely compromised.
- Rapid Response Profile: Engineered to launch from a trailer or bespoke trolley within ten minutes of a callout, the craft features a low profile allowing it to navigate seamlessly under low bridges during tidal peaks.
- Ergonomic Central Console: The "CC" central console layout provides maximum deck access, optimal weight distribution, and unobstructed sightlines for the skipper, making it much easier to recover casualties or divers over the side.
