Buying Guide

  1. What is Type IV buoyancy? Type IV throws provide emergency flotation but are not life jackets. They’re designed to be thrown to a person in the water and can be used as a seat cushion when not in use.
  2. Choosing visibility vs. subtlety. Red and orange options offer rapid identification in distress, while blue or white variants may blend with surroundings. Pick colors that contrast with typical water and hull tones on your vessel.
  3. Versatility considerations. If you need both seating and flotation, a cushion that doubles as a seat can reduce clutter and increase readiness on small boats or canoes.
  4. Durability factors. Look for a rugged nylon shell and well‑sealed foam for longevity against sun, salt, and abrasion on deck or cockpit areas.
  5. Placement and storage. Store cushions in accessible, dry locations. Consider quick‑release straps or clips for rapid deployment in emergencies.
  6. Boat size alignment. For larger boats or high‑activity groups, multiple devices (or one large cushion) may improve coverage and reduce response time in a true emergency.

Frequently Asked Questions

  • What is a Type IV flotation device? It is a throwable flotation aid approved by the USCG intended for emergency use and may also function as a seat cushion when not thrown.

  • Are these cushions weatherproof? Cushions with a nylon outer shell are designed to resist abrasion and exposure to marine elements, but drying after use is recommended to prolong life.

  • Should I buy more than one? For family or crewed vessels, having multiple throw cushions improves readiness and reduces response time in emergencies.
