Rowing, stand-up paddling, or open-water swimming – you seek freedom in your element. But true freedom begins in your mind when you know you have a reliable backup with you. Even skilled, experienced water sports enthusiasts can get into trouble due to sudden currents, cramps, or exhaustion. An inflatable safety buoy gives you exactly the peace of mind you need to enjoy your water sports to the fullest.
Both the BEACH/ONE and the ACTIVE are built on the same proven system: the RSS – RESTUBE Safety System. A single pull on the trigger instantly inflates the buoy via a CO2 cartridge within seconds. In its inactive state, it is so compact and lightweight you won't even notice it. After use, simply replace the cartridge, and you are ready for your next session.
The difference lies entirely in how they are used. Here is a direct comparison to help you find the product that perfectly fits your water activities.
BEACH/ONE or ACTIVE: Who Needs Which Backup?
BEACH/ONE – Your Companion for Every Day on the Water
Relaxed beach days with the family at the lake or snorkeling along the coast – the BEACH/ONE is designed for everyone who occasionally enjoys the water in coastal or calm areas. It is our smallest and lightest version, providing 50 N of buoyancy to give you what matters most in, on, and around the water: a completely clear head.
"I hope I never have to use the Restube Beach!! But it has given me so much confidence in open water because I know that if anything goes wrong I have my own personal airbag. A great idea, thanks. "
– Paul C.
ACTIVE – For Everyone Who Heads into the Water Regularly
Whether it's stand-up paddling, triathlons, rowing, open-water, or ice swimming – the ACTIVE is our best-selling all-rounder for anyone who goes into the water regularly. It is designed to be more robust and offers features specifically tailored to active water sports. The buoy itself is larger, giving you an even more secure and comfortable feeling when resting on it. With 75 N of buoyancy, it keeps you safely afloat even when wearing a wetsuit, carrying gear, or navigating rougher waves. The ACTIVE is the perfect choice if you want to venture beyond the surf zone.
“Despite the escort boat, you swim out there alone. RESTUBE Safety Buoy helps me keep my focus while swimming. The super small Safety System has no flow resistance and is weightless in the water. A pull on the trigger inflates the yellow Safety Buoy in seconds, which gives me an even better feeling.”

50 N vs. 75 N: Buoyancy, Dimensions & Weight
BEACH/ONE and ACTIVE differ in buoyancy and buoy length – here are the differences in a direct comparison.
- The BEACH/ONE offers 50 N of buoyancy (~5 kg / 11 lbs). This keeps your head safely above water and provides a stable breathing position in standard swimwear and calm conditions. Additionally, at only 160 g (5.6 oz), the BEACH is a true featherweight and extremely compact with a buoy length of 50 cm (19.7 in).
- The ACTIVE, on the other hand, delivers 75 N of buoyancy (~7.5 kg / 16.5 lbs). This makes all the difference when you are not just in calm waters: in waves, currents, or when wearing extra clothing. Once inflated, the larger buoy offers enough surface area to lean on and catch your breath. With a buoy length of 65 cm (25.6 in) and a weight of 195 g (6.9 oz), it is slightly heavier than the BEACH/ONE due to the higher buoyancy – but remains just as compact with a pocket size of 14 x 7 x 4 cm (5.5 x 2.8 x 1.6 in).

Smart Features: More Than Just a Buoy
Maximum Flexibility: Wear It Your Way
While the BEACH/ONE is fastened horizontally at the hip, the ACTIVE can be worn both horizontally and vertically. This is a real advantage, especially for triathletes and open-water swimmers: the vertical wearing position reduces water resistance to virtually zero. Furthermore, the RESTUBE ACTIVE is officially approved as a safety buoy by World Triathlon, DTU, and USA Triathlon.

Details & Extras
The ACTIVE model stands out with clever extras that can make a vital difference in an emergency:
- Signal whistle: Integrated into the buckle to draw acoustic attention to yourself.
- Positioning bar: Stabilizes the buoy when inflated for an even more secure position.
The BEACH model does not feature these extras to ensure maximum compactness at an attractive entry-level price.

The Right Choice for Every Water Moment: Find Your Perfect Backup
Choosing between the RESTUBE ACTIVE and the BEACH/ONE depends entirely on your activities in, on, and around the water. If you are occasionally out in coastal or calm waters, the BEACH/ONE is your ultimate companion. If you are regularly in the water, sometimes further away from the shore or in changing conditions – then the ACTIVE is your backup.
They both have one thing in common: They give you the freedom to experience the water just the way you love it – bold, alive, and with a feeling of absolute peace of mind.
