The Voices of the Community

The wind was so strong that I lost my board and then the kite. I was completely exhausted and desperate when I remembered the RESTUBE safety buoy on my harness. Luckily! I made it to shore with the buoy.

Alexandr

We have a lot of experience but still my son and I completely underestimated the sea and its forces. Thanks to the additional buoyancy provided by the RESTUBE safety buoy, I was able to get us both to shore.

Jürgen

When I was stung by a jellyfish in the open sea, I knew I needed help as soon as possible. I used the safety buoy to attract attention and luckily a fishing boat spotted me straight away.

Pia

I rescued a 7-year-old boy who was completely overwhelmed and way too far out with his SUP. Would I have swum to him without my RESTUBE safety buoy? I don't think so!

All FAQs

Why do I need additional buoyancy when kitesurfing?

Additional buoyancy can often resolve a problematic situation in the water, and knowing that you have buoyancy with you just in case will allow you to enjoy your kite adventure more freely and relaxed.

Remember, even the best equipment can be damaged or you can be unexpectedly separated from your equipment. Having additional buoyancy directly on your body and with you at all times is vital. Other people in the water may also need help. By handing them a buoyancy compensator from a safe distance, you can help them effectively without putting yourself in danger.

Who is EXTREME for?

EXTREME is made from extra strong buoy and bag material, making it ideal for rough conditions in and on the water. The split pin closure also prevents accidental opening of the bag.

EXTREME is suitable for kitesurfing, windsurfing, surfing and stand-up paddling in waves or on the river.

Can I use the RESTUBE Safety Buoy more than once?

Yes, after replacing the CO2 CARTRIDGE, the Safety Buoy is immediately ready for use again. The sales package contains the safety buoy incl. an original RESTUBE CO2 CARTRIDGE that must be screwed in before use. After use, the safety buoy is very easy to prepare for use again: Deflate, insert a new cartridge, fold the buoyancy chamber according to the printed instructions, and stow the whole thing in the pouch! ATTENTION: Only original RESTUBE CO2 CARTRIDGES are 1.) 100% quality tested, 2.) seawater resistant, 3.) level tested and 4.) the necessary release force is matched to the release. The cartridges comply with the standard for life jackets DIN EN ISO 12402-7. If other cartridges are used, it cannot be guaranteed that the safety buoy will fill without problems in an emergency and the trigger may be damaged.

Detailed instructions for how to get the Safety Buoy ready to go again are available in our blog: https://restube.com/blogs/news/how-to-pack-restube-care-and-maintain-correctly

How many times can a CO2 cartridge be used?

A CO2 cartridge can be used to trigger the Safety Buoy once. Afterwards, the empty CO2 cartridge must be removed, and a new original RESTUBE CO2 cartridge must be inserted.

This is simple, and only takes a few steps. You can view an instruction video here: https://restube.com/blogs/news/how-to-pack-restube-care-and-maintain-correctly

You can also blow up the Safety Buoy manually using the mouth valve. This is a practical option if you are using the Safety Buoy as a swim buoy, or for snorkeling.

You can purchase a 2-pack of original RESTUBE CO2 cartridges from our shop!

What safety rules should I follow when kitesurfing?

VDWS highlights 11 safety rules: pick a spot with enough free space (three line lengths), kite only in wind you can handle, check all gear before launch, always use your leash and quick-release, wear proper protective equipment, respect others on the water, know the rules of navigation and priority, and never kite alone. DLRG adds: don’t go farther than you can swim back, secure kite/board when not in use, and call 112 quickly in an emergency. Always check weather and wind, keep launch/landing zones clear, and set up a rescue plan. Follow these, and you’ll keep your sessions safe – for yourself, others, and the environment.
