Cannon Clamp Mount Downrigger Base – Black Aluminum, Corrosion-Resistant Gunwale Clamp

Overview

Engineered for marine use, the Cannon Clamp Mount Downrigger Base provides a reliable, drill-free way to mount your downrigger. The black aluminum body resists salt spray and UV exposure, keeping its finish intact season after season. For harsher environments, the stainless steel version adds extra corrosion protection. This base works with Cannon lineups and adapts to a range of boats, from casual weekend rigs to rental fleets. It anchors your rig securely while still allowing quick removal when you are off the water, keeping setup tidy and ready for your next trip.

Key advantages

• Secure gunwale/transom clamping enables removable, damage-free installation without drilling
• Compatible with Lake-Troll, Sport-Troll, Legacy Easi-Troll, and Mini-Mag downriggers
• Machined aluminum construction with powder coating resists corrosion for long-term marine use
• 2-inch maximum opening fits most small boat gunwales and transoms
• Portable installation ideal for rental boats or multiple vessels

Clamping around a gunwale or transom without drilling keeps the boat’s original structure intact and simplifies moving between vessels. The 2-inch opening accommodates most small boats, while the powder-coated aluminum delivers durable performance under spray, sun, and salt. The design accepts 9 or 12 inch tubes with 1-1/2 inch outer diameter, balancing reach and stability. The ability to set a downrigger at a 30° angle within flush-mounted rod holders can help you optimize line management in tight rail spaces. For rentals or shared boats, the portable installation keeps gear secure without permanent modifications.

Technical details

• Tube lengths: 9 or 12 inches
• Outer diameter: 1-1/2 inches
• Maximum clamp opening: 2 inches
• 30° flush-mount rod holder compatibility

Compatibility and setup are designed for flexibility. The base works with legacy Cannon downriggers including Lake-Troll, Sport-Troll, Legacy Easi-Troll, and Mini-Mag for specific configurations. Install quickly by clamping to the gunwale or transom, select the tube length that fits your boat, and align your downrigger position. The result is a sturdy, adaptable foundation that stays secure through long days on the water, while still being straightforward to remove when needed.

On the water

On the water, you’ll enjoy a low-profile footprint that keeps lines clear and rails unobstructed. The 30° flush-mount option lets you tuck rods into angled holders, freeing space for electronics and gear. The combination of precise machining and a secure clamp delivers dependable alignment as you navigate waves and spray, giving you peace of mind to focus on the catch.
