Water Safety Guide for Stand-Up Paddling

SUP is not inherently more dangerous than other water sports, but it carries real risks that are often underestimated. In Switzerland, SUP accidents have increased by around 50% since the sport's boom in 2015 (Suva), and in the US, SUP fatalities rose from 11 to 29 between 2023 and 2024 (US Coast Guard). Notably, more than half of fatal boating accidents in the US in 2024 happened in calm water with light wind and good visibility – not during storms – which shows that overconfidence in seemingly easy conditions is a bigger risk than bad weather. With the right preparation, a buoyancy aid, and respect for wind and current, SUP can be enjoyed safely.

A PFD (Personal Flotation Device) is the umbrella term for a CE-certified buoyancy aid in the 50N class that keeps you afloat in the water – from the classic foam vest to the compact, inflatable PFD by RESTUBE. The PFD is ideal anywhere a certified buoyancy aid is required by law: in Switzerland and at Lake Constance, for example, there's a requirement to carry one beyond 300 metres from shore. But even without that obligation, it can be life-saving – giving you crucial buoyancy exactly when you need it most.

Yes, many dogs enjoy paddle boarding once they're introduced to it gradually. Start in calm, shallow water, let your dog find their own pace, and stay close in case they panic or misjudge their own strength. A dog life jacket like the RESTUBE Dog Life Jacket gives them a stable swimming position and extra visibility. The carry handle lets you lift them out of the water quickly if needed – especially helpful for puppies, older dogs, or first-time swimming experiences.

It depends on the water you're paddling on: on flat water like lakes or near-shore sea, a classic ankle or calf leash is enough, such as the °hf Connect SUP Board LEASH. On rivers, in tidal waters, or anywhere with strong currents, switch to a quick-release waist leash like the ­°hf­ Synergy SUP BELT instead, which lets you detach instantly if you get caught.

Falling into the water can happen to anyone, whether you're a beginner or a pro and it's usually harmless. Stay calm and always wear a buoyancy aid like the RESTUBE safety buoy or the PFD by RESTUBE, so you have instant buoyancy in an emergency while you get your bearings and climb back onto your board. Keep your leash attached the whole time so your board doesn't drift away.

Yes, every SUP board has a maximum weight capacity set by the manufacturer, typically listed in the product specs (often somewhere between 90 and 150 kg, depending on the board's size and volume). This includes your own body weight plus any gear, and a dog if you're bringing one along. Staying within that limit matters for safety, not just comfort: an overloaded board sits lower in the water, becomes less stable, and loses buoyancy reserve exactly when you might need it most.

Start on calm, windless water, and consider taking a beginner's course. Check wind, current, and weather before every session, wear a buoyancy aid, and tell someone where you're paddling and when you'll be back. That way you build experience without exposing yourself to unnecessary risk.

As a rough guide, wind speeds up to around 10–12 knots (roughly 18–22 km/h) are manageable even for less experienced paddlers. Once whitecaps start appearing – typically from around 12–15 knots – conditions get more challenging and it's time to head back. Offshore wind in particular can push you out faster than you can paddle back. As a beginner, paddle against the wind and current first, so you don't run out of strength on the way home.

Yes, winter SUP is possible, but it calls for extra precautions: below 18°C (64°F) water temperature, wear a wetsuit to help prevent hypothermia (5/4mm or thicker below 10°C/50°F). Never go out alone and check beforehand for ice or local restrictions. If you have any known heart or circulatory conditions, check with a doctor first, since cold water puts extra strain on your cardiovascular system.
