Buying Guide
What Am I Buying?
Flotation foam cushions are throw-style devices that also double as seat cushions. Look for USCG Type IV approval for reliable emergency buoyancy on boats over 16 feet, and a durable outer shell designed for marine use.
What Size Do I Need?
Common sizes include 15″ x 15″ cushions for quick accessibility and portability, with larger cushions useful on bigger watercraft. Consider your boat’s layout and storage space when selecting cushion size and quantity.
What Materials Should I Expect?
Typical construction uses a durable nylon or polyester outer shell with closed-cell polyethylene foam. Closed-cell foam resists water absorption and maintains buoyancy, while the outer shell protects the foam from abrasion and sun exposure.
Should I Choose A Dual-Use Cushion?
Dual-use cushions function as emergency flotation devices and as comfortable seating. If you frequently fish, cruise, or transport passengers, a dual-use option can streamline safety gear and seating needs.
Color and Visibility
Choose high-visibility colors (orange, blue, or white) for quick recognition in water. Blended camouflage is attractive for aesthetics but may reduce immediate visibility in rough conditions.
Storage And Maintenance
Store cushions in a dry, shaded area when not in use. Inspect the outer shell for tears and the foam for signs of compression or wear. Rinse with fresh water after saltwater use to extend life.
Installation And Handling
Keep flotation cushions easily reachable on deck or within reach of seating areas. Practice grabbing and throwing for emergency readiness, especially if you operate a boat with children or guests aboard.
FAQ
- What does USCG Type IV mean? A Type IV device is a throwable flotation cushion designed to help keep a person afloat in an emergency. It is not a wearable PFD.
- Can I use these as regular seating? Yes. Many cushions double as seat cushions, but they are primarily designed for flotation in emergencies or temporary seating on deck.
- Are all cushions waterproof? Cushions use closed-cell foam and a waterproof outer shell to resist water absorption, but some covers may still require drying after exposure.
- How many cushions should I have? The number depends on your vessel size and crew. A typical setup includes at least one cushion per seating area and an additional throw in reach for emergencies.
- Are colors important for safety? Bright colors improve visibility in distress. Camouflage options are more for aesthetics but may be harder to spot in low-light conditions.
- Do cushions come with warranties? Warranties vary by product; check the listing for details on coverage and replacement terms.
