10 Best Kayaks For 500 Lb Capacity 2025 in the United States

The Old Town Sportsman AutoPilot 136 is a sturdy, motorized fishing kayak designed for anglers who need a high weight capacity—it can hold up to 660 pounds, which is well above the 500 lb threshold. Measuring 13 feet 6 inches in length, it offers good stability and space for both gear and a person, with a usable capacity of 427 pounds for rider plus equipment. Made from single-layer polyethylene, the kayak is durable and built to withstand rough conditions, including saltwater use.

One of its standout features is the built-in Minn Kota trolling motor with GPS and Bluetooth control, allowing you to easily maneuver or hold your position on the water with Spot-Lock technology. This makes fishing less tiring and more precise. However, the motor’s battery is not included, so that’s an extra cost to consider. The kayak also includes multiple accessory tracks and rod holders, a comfortable removable mesh seat, and adjustable foot braces that improve control and comfort during long trips.

At 158 pounds (plus 24 pounds for the motor console), it’s on the heavier side, which might make transport and launching a bit challenging without help or a cart. It doesn’t come with a paddle, so you’ll need to get one separately. Storage is decent with customizable tracks and a tackle box included, making it easier to organize fishing gear. This kayak provides a balanced combination of comfort, control, and tech features, making fishing trips more enjoyable for serious anglers who want a powerful, feature-rich vessel capable of handling heavy loads and motorized assistance.

The Sea Eagle 380x Inflatable Kayak is a strong option for people needing a kayak that supports a high weight capacity—up to 750 pounds. This makes it suitable for two to three adults plus gear, which is great for families or groups wanting to paddle together. It measures 12 feet 6 inches long and 39 inches wide, offering good stability and enough space inside for comfort during longer trips. Made from tough 1,000-denier polyester material, it resists punctures well, which is reassuring if you plan to kayak in rocky or rough waters. It inflates fairly quickly, in about 8 minutes, making it convenient to set up.

The kayak is rated for whitewater up to Class IV, so it can handle moderately challenging conditions, appealing to more adventurous users. The Pro Package adds value by including paddles, comfortable tall back seats, a carry bag, storage bags, a hand pump, a skeg for better tracking, and a repair kit—everything needed to get started right away. One thing to note is that the kayak weighs around 40 pounds, which is manageable but might be a bit heavy for some to carry alone. Also, while the material is durable, as an inflatable kayak it will require some care to avoid damage and needs proper inflation to perform well.

This kayak is ideal for those who want a spacious, sturdy, and well-equipped inflatable kayak with a high weight capacity, especially for recreational use on lakes, rivers, and some whitewater.

The Sea Eagle 437ps PaddleSki is a unique inflatable catamaran-style kayak ideal for users needing a high weight capacity—up to 855 lbs. This makes it perfect for two people with gear, fishing trips, or even light motor use (up to 6 hp). Its 172-inch length and 48-inch width provide a stable platform, supporting activities like standing and casting, which many kayaks can’t easily accommodate. The construction uses durable 1000 denier polyester PVC fabric with a drop-stitch floor, offering good puncture resistance and rigidity uncommon in inflatables.

It inflates quickly with five separate air chambers for safety, and deflates to fit in a car trunk or small storage space. The included swivel seats add comfort for long outings. The kayak is relatively heavy at 88 pounds, which may make transport and setup a bit challenging for some. Also, while versatile, it requires some time to inflate and assemble compared to rigid kayaks.

If you want a multi-purpose boat for paddling, fishing, and motor use that can hold heavier loads, this Sea Eagle model is a strong option. Those prioritizing ultra-lightweight or minimalist design might find it bulkier than other kayaks.
