A Type IV is a throwable personal flotation device designed to be tossed to someone in the water. It’s typically a buoyant cushion or ring that helps a person stay afloat until they can be brought back aboard or reach safety.

• Not worn: It’s different from a life jacket; there’s no sizing or straps to wear.
• Quick to deploy: Keep it within easy reach of the helm or deck.
• Look for approval: Many cushions are labeled “USCG Type IV” to indicate they meet recognized standards.
• Grab points: Most include webbing or straps to hold onto or to attach a throw line.

It’s an important backup to your wearable life jackets.

Requirements can vary by state, waterway, and boat type. Many recreational boats are expected to carry a USCG‑approved Type IV throwable in addition to wearable life jackets, often based on vessel length and where you operate.

• Check current rules: Review your state boating laws and applicable federal guidance before heading out.
• Know the exceptions: Some small craft and paddlecraft may have different requirements.
• Keep it accessible: Stow your throwable where it can be grabbed and tossed immediately.

If you’re unsure, consult your local boating authority. Having a Type IV on board can add an extra layer of safety even when not explicitly required.

Type IV cushions are helpful, but they have limitations to keep in mind:

• Not wearable: They don’t replace a properly fitted life jacket.
• User dependent: They work best when the person in the water is alert and within throwing range.
• Drift and reach: Wind, waves, and boat speed can make accurate throws harder.
• Limited support: They provide flotation but don’t keep airways clear like some wearable devices.
• Durability: Prolonged sun exposure or using it as a seat can compress foam and reduce performance.

Because of these factors, boaters often carry a Type IV as a supplement to wearable PFDs and practice safe throwing techniques.

Focus on visibility, durability, and compliance. These tips can help you pick a solid option:

• Approval marking: Look for a clearly labeled “Type IV” and approval statement on the cushion.
• High visibility: Bright colors or reflective accents can make it easier to spot.
• Rugged cover: A durable nylon or vinyl shell and strong stitching hold up to marine use.
• Secure grab straps: Webbing that’s easy to grip can aid a faster rescue.
• Fit and storage: Choose a size that’s easy to throw and store within reach.

Once you pick one, add it to your pre‑departure checklist so it’s always ready when you need it.

For use:

1. Alert and aim: Shout to the person overboard and toss the cushion past them so it drifts within reach.
2. Maintain sight: Keep pointing and talking to help guide them. If you’ve attached a floating line, pull gently as needed.
3. Assist recovery: Prepare to bring them aboard safely when conditions allow.

For care:

• Rinse and dry: After use, rinse with fresh water and let it dry completely.
• Inspect often: Check for tears, loose straps, or waterlogged foam and replace if compromised.
• Store smart: Keep it out of direct sun when possible and immediately accessible while underway.

Regular upkeep can help maintain performance over time.
