738 Avalon Plank

738 Avalon Plank: A 7×3-Foot Inflatable Floating Platform for Lakes, Sandbars, and Marinas

Whether you're anchored at a sandbar, tied up at a marina, or floating on a calm lake, the 738 Avalon Plank from Further Customs gives your group a dedicated place to spread out and enjoy the water. At 7 feet long, 3 feet wide, and a full 8 inches thick, this inflatable swim platform delivers a surprisingly solid, stable surface — one that makes it easy to sunbathe, fish, relax, or simply give guests somewhere comfortable to sit when your boat is at capacity.

What Makes the Avalon Plank Worth a Closer Look

• Generous 21 square feet of surface space — enough room for multiple people to stretch out without feeling cramped, making it a practical choice for families and small groups.
• 8-inch thickness provides meaningful buoyancy and a noticeably firm, stable feel underfoot — far more reassuring than thinner inflatable mats that flex and wobble.
• Versatile across water environments — equally at home in freshwater lakes and calm marina settings, so it travels well from one outing to the next.
• Extends your boat's usable space — a practical solution when you have more guests than deck room, giving everyone a spot to relax without crowding the boat itself.
• Supports multiple activities — lounging, sunbathing, fishing, or simply using it as a swim platform to jump off and climb back onto.

Who This Platform Is Best Suited For

The Avalon Plank is a strong fit for boaters, lake house regulars, and anyone who spends meaningful time anchored in calm water. It works especially well for groups that want a designated gathering spot away from the boat — a floating island where people can rotate in and out of the water, dry off, and relax without constantly climbing back aboard.

It's also a practical pick for fishing enthusiasts who want a stable, comfortable platform to cast from, or for families with kids who want a safe, defined area to play near the boat. If you're looking to build out a more complete on-water setup, it pairs naturally with the Avalon Bar for added convenience and social space, or with the 778 Avalon Dock if you're considering a more permanent floating solution.

Practical Considerations Before You Buy

Because this is an inflatable platform, it's designed for calm to moderately calm water — sandbars, sheltered coves, marinas, and inland lakes are ideal environments. It's worth thinking about how you'll anchor or tether it when in use, since an unattached platform can drift with wind or current.

At 7×3 feet, the footprint is compact enough to store and transport without much hassle, but spacious enough to genuinely accommodate a small group. If your outings regularly involve larger gatherings, it's worth considering whether a single plank covers your needs or whether a complementary dock setup — like the 778 Avalon Dock — makes more sense for your situation.

Overall, the 738 Avalon Plank is a well-conceived product for anyone who wants to get more out of their time on the water — more space, more flexibility, and more room for the people who matter.
