2026 Avalon GEOfish Rear Fish - 21 FT
Description
Meet the 2026 Avalon GEOfish Rear Fish, a 21-foot pontoon that’s equal parts “let’s cruise” and “let’s catch dinner”—all wrapped in a Sage Metallic finish that looks right at home on glassy morning water or under a golden-hour sky.
At just over 21 feet long (21.4’, to be exact) with a confident 102-inch beam, this pontoon brings that satisfying “big-boat” feel without losing its easygoing personality. The aluminum hull rides on two pontoons sized for stability and smooth manners, giving you a steady platform whether you’re stepping aboard with a cooler in hand or setting up for a few peaceful casts. Those pontoons stretch out to 240 inches in length and carry a 25-inch diameter—built to feel planted, not twitchy, when the lake gets lively.
The “Rear Fish” name isn’t just for show. When it’s time to trade cruising for casting, you’ve got two fishing pedestal chairs ready to turn the back of the boat into your personal angling zone, plus a baitwell pump to keep the action moving. It’s the kind of setup that makes early starts feel less like work and more like a tradition you actually look forward to.
Of course, not everyone onboard is there to talk tackle—and this GEOfish gets that. The layout is made for hanging out, too, with three cockpit sofas and two cockpit chairs for easy conversation, snack-sharing, and shoreline sightseeing. Up front, the open bow offers five seats—perfect for the friends who want the best breeze, the best view, or the best spot to claim as “their” seat for the day.
At the helm, you’ll find a straightforward, comfortable captain’s chair paired with remote outboard steering control, so you can focus on the water and the good company instead of wrestling the wheel. There’s also a fuel level gauge, because “Are we good on gas?” is a question that’s way more fun when it has an instant answer. And with a 25-gallon fuel capacity, you’ve got the range for full afternoons that turn into “one more cove” evenings.
Bring your playlist, too. A Fusion® audio system with Bluetooth® makes it effortless to set the mood—laid-back acoustic for a slow cruise, or something with a little more bounce when the crew’s feeling celebratory. Underfoot, vinyl cockpit flooring keeps things practical and comfortable, ready for wet feet, sandy toes, and the occasional “oops” that comes with real lake days.
When the sun is high, the Bimini top is there to keep the hangout going without everyone squinting or retreating. It’s shade when you want it, open sky when you don’t—simple, useful, and exactly what a day on the water needs.
And power? This Avalon is happy across a wide range, with a minimum recommended 9.9 horsepower all the way up to a maximum recommended 500 horsepower. Whether your style is easy cruising or you want the kind of punch that makes wide-open water feel like a playground, this platform is ready to match your plans.
The 2026 Avalon GEOfish Rear Fish in Sage Metallic is the rare pontoon that doesn’t make you choose between “family day” and “fishing day.” It’s built for both—and it’s built to make both a lot more fun.
