The heart of every SipaBoard is a jet propulsion engine with an integrated compressor – the SipaDrive. This pumps up your SUP for you in less than 5 minutes, and then makes it smoother and more stable when you get going. Our jet-propulsion system is hidden inside the plastic housing built into the board, virtually eliminating drag when the engine is off and you want to paddle yourself. The SipaDrive is emission-free and barely audible, so you can take it even on protected waters and enjoy the peace and quiet. It provides 3 hours of fully assisted cruising at a speed of 2 knots.
