REEF Mats are designed to support thousands of pounds without sinking. Your whole family, extended family, friends, neighbors, friends of friends, event pets will be able to float all day!

The short answer is. There really isn't a safety limit to the weight of each mat, but at the following weights and capacities, the mat will start to submerge a bit:

• REEF 48: ~800lbs (3-4 people)
• REEF 85: ~1200lbs (4-6 people)
• REEF-123: ~1600lbs (6-8 people)
• REEF-129: ~2400lbs (10-12 people)
• REEF HEX 82: ~2000lbs (8-10 people)
• REEF HEX 101: ~1600lbs (6-8 people)
• REEF HEX 112: ~2000lbs (8-10 people)

Our manual hand pump is designed specifically for REEF mats and to move a high volume of air fast. The included manual pump does a great job quickly filling your mat to pressure.

Average Fill Times (assuming consistent/steady pumping pace)

• REEF 48 – 1.5 minutes
• REEF 85 – 2.5 minutes
• REEF 123 – 4 minutes
• REEF 129 – 6 minutes (includes 120v electric pump)
• REEF HEX 82 – 4 minutes
• REEF HEX 101 – 3.5 minutes
• REEF HEX 112 – 4 minutes

The pump has a built-in pressure gauge that will tell you when your REEF’s PSI reaches the perfect level. Recommended PSI for REEF is 2 to 5 PSI depending on desired firmness (3.5 PSI is our favorite).

This answer starts with another question – what does your power source look like?

1. If you have shore power (standard 120v outlet), our 120v AC medium-pressure pump is awesome – and fast! This pump will fully inflate your mat to the optimal pressure (3.5 PSI) in no time. It’s a great option if you have a 120v outlet and want to get out on the water as fast as possible.

Wondering about using a converter on your boat? Note: The 12v system in boats does not provide a sufficient amount of power for most high-pressure pumps. So, purchasing a 12v to 120v converter is not an option. The only solution for a robust on-board 120V AC system would be to install an inverter of sufficient wattage to provide the level of power needed by high-pressure pumps.

2. If you’re out on the boat and don’t have a 120v outlet, use our 12v DC low-pressure pump. This pump conveniently plugs into the 12v accessory power adapter (cigarette lighter) and works quickly to get most of the air in (or) out of your REEF mat. This pump will do most of the work – but it will only take your mat up to about 1 PSI. So, now you’ll want to use the included hand pump to increase the firmness of the mat. (We recommend 2 ½ PSI for medium firmness. If you want a dock-like experience, you can increase the pressure up to around 5 PSI).

While it’s a two-step process, most customers like this option for the boat because our 12v pump is super-fast and does 90% of the work for you!

3. Mission’s High-Pressure 12v DC Electric Pump can fill REEF to any pressure that you desire, but the trade-off is speed. Fill times for REEF mats will be 10+ minutes. But if you only have a 12v DC power source, and do not want to do any manual pumping whatsoever – then this is your best option!

This pump was originally designed for inflating iSUPs to high-pressures and uses the same connection port as REEF mats.
