2024 Extreme Boats 646 Walk Around

The 2024 Extreme Boats 646 Walk Around is a 21-foot aluminum bay boat built for fishing and extended time on the water. Its deep-V hull design provides stability and efficiency across varied water conditions. Powered by a single 225 hp Mercury outboard, the boat cruises at 35 knots and reaches a maximum speed of 45 knots.

The layout centers on practical fishing functionality. A forward cabin offers modest overnight accommodations, and a head is included for convenience during longer trips. The walkaround design provides access around the boat's perimeter, typical of the category.

Standard equipment includes trim tabs for improved handling and performance. The aluminum construction suits both freshwater and saltwater use.
