Stainless Steel Windshield Trim

Cobalt R8 outboard with sport tower and blue sunshade running at speed on open water with Yamaha outboard

Sport Tower with Sunshade

The sport tower with sunshade provides overhead coverage for the cockpit with a durable, mounted design. An additional aft extension offers expanded shade for rear seating.

Coastal Edition

The Coastal Edition is engineered for enhanced saltwater durability and long-term performance. It includes corrosion-resistant stainless steel components, watertight electrical systems, and an advanced water management design to help protect against harsh marine environments.

Rotating Sunshade

The Rotating Sunshade stays in place as the arch is lowered, maintaining coverage without adjustment. A rigid frame and assisted operation make it easy to use while keeping the canvas secure.

Fender Clip Package

The Fender Clip Package offers a quick-mount system for securing fenders at optimal positions. It simplifies docking by keeping lines set and ready for use.
