The KingFisher 3425 GFX is a heavy-gauge welded aluminum offshore fishing boat built around a simple promise — Great Fishing & Exploring. At 35’1″ with a 10′ beam and up to 900HP, the 3425 GFX delivers the power, range, and capability to take serious anglers further offshore and bring them home in comfort.

At the heart of every 3425 GFX is KingFisher’s proprietary Pre-Flex® hull technology. This trademarked process creates a stronger, lighter hull with a variable 18° deadrise and signature shearwater bow that stays composed in changing offshore conditions. Beneath it all, an internally reinforced structural impact grid, heavy-duty keel guard, 0.250 bottom thickness, and 0.160 sides deliver the structural integrity you need when you’re running far from shore.

With 300 USG / 1,135L of fuel capacity and a layout engineered around both performance and usability, the 3425 GFX is equally at home on a long offshore run or a full day anchored on productive grounds. The 10’11” cockpit is purpose-built for serious fishability, featuring a 139 USG floor fish locker and 52 USG transom fish locker, while the 11’3″ cabin delivers 6’10” of headroom, a 6’2″ v-berth, generous seating, and thoughtful storage throughout — comfort without compromise.

For those looking to take the experience even further, the 3425 GFX offers the option to integrate a Seakeeper gyroscopic stabilization system. Seakeeper actively eliminates up to 95% of boat roll — reducing fatigue, seasickness, and strain — so you arrive at the grounds fresh and focused. It’s a refinement you feel immediately, transforming long offshore runs into something smoother, more controlled, and more enjoyable.

The KingFisher 3425 GFX is backed by a lifetime hull warranty and supported by an authorized dealer network across North America. Build yours today or find a KingFisher dealer near you to arrange a demo on the water.
