Hi Robin, I paddled both for 20 mins on tidal canal flat water. Boost LV @ 9.2kmh v. VauIt @ 9.8kmh. The Boost LV was incredibly stable so I bought it. As much as I liked the Vault for it's speed, it was a bit of a tight squeeze for my wide hips and I felt a little uncomfortable in it. On the other hand, the Boost LV at 42cm has an extra 2cm of bucket width and it felt a lot better. Also I want to venture outside and feel the Boost LV a safer bet.
