Taylor Made Dock Floats 24″x48″x12″

Taylor Made’s dock floats use a UV-resistant black polyethylene shell to shield an EPS foam core. This combination protects the core from saltwater, gasoline, and other harsh chemicals, reducing the risk of sinking if the shell is damaged. The floats are designed for straightforward installation with mounting flanges and slots. Available in multiple sizes to achieve approximately 335 to 1,200 pounds of flotation per unit, allowing flexible configuration for different dock layouts and load requirements.
Eagle Float Dock Float 2’x4’x8″

The Eagle Float is positioned as an industry-trusted option, combining a 100% virgin polyethylene shell with a solid EPS core. The design emphasizes durability and resistance to UV and weathering. Installation is simplified by molded mounting slots on the foam-filled top for easy attachment to docks or piers. It’s built to withstand marine exposure and is offered in multiple sizes to accommodate a range of dock configurations. Note that attachment hardware is not included in the package.
Dock Edge + Float Howell 250

The Dock Edge Howell 250 features a 260-pound flotation capacity and a durable foamed shell. This option is paired with Dock Edge + hardware for reliable compatibility across a range of Dock Edge products. The 10-year warranty offers long-term reassurance for users seeking a dependable, mid-range solution for smaller to mid-size dock setups.
JEZERO Deep Water Floats (2 Pack)

JEZERO Deep Water Floats are designed for markers and light-duty buoy applications. They leverage high-density closed-cell foam for buoyancy, making them suitable as trail markers, dock markers, or small mooring aids. The bright red and white color combination enhances visibility on the water, and the pair provides budget-friendly versatility for users who need float support without heavy-duty load requirements.
Dock Edge + Float Howell 550

The Howell 550 model adds a higher flotation capacity (550 lbs.) for heavier docks and more demanding load scenarios. Like other Dock Edge products, this float is designed to work with Dock Edge hardware and includes a foam core inside a protective shell. This option suits larger platforms or decks that require additional buoyancy without sacrificing stability.
Buying Guide: Key Considerations For Styrofoam Dock Floats
When selecting styrofoam dock floats, consider shell material, foam core, load requirements, and installation needs. The following perspectives help cover essential trade-offs and scenarios.
- Durability vs. buoyancy: A thicker shell or UV-resistant outer shell protects the foam core from saltwater, gasoline, and environmental exposure, reducing maintenance needs and the risk of sinking if the shell is compromised.
- Load capacity and dock size: Choose floats with flotation ratings that match your dock’s total weight when loaded, including people, equipment, and weather-related factors like wind and waves. Heavier docks may benefit from higher-capacity models (such as 550 lbs or more).
- Installation compatibility: Some floats include mounting flanges or integrated mounting slots. Ensure they align with your existing dock hardware or plan for the necessary mounting hardware to complete installation.
- Core material and repairability: EPS foam cores are common and effective, but consider how easy it is to replace or seal the core if the outer shell is damaged. Higher-grade shells typically offer longer service life.
- Visibility and marking: For marker or buoy applications, bright colors (red, white, or high-contrast combos) improve pass-by visibility in low light or crowded water spaces.
- Use-case alignment: For permanent docks, higher-capacity, UV-stable floats may provide longer service life. For temporary setups or seasonal docks, cost-effective, lighter floats may be more practical.
- Warranty and support: Models with warranties (such as 10-year coverage) provide long-term value and protection against manufacturing defects or early wear.
Overall, select floats that balance buoyancy, durability, and ease of installation for your specific dock configuration. If frequent exposure to harsh elements or heavy loads is expected, prioritize higher flotation ratings and UV-stabilized shells. For simple, temporary, or budget-conscious projects, lighter or smaller floats with straightforward mounting may be sufficient.
