Hi Lucas, yes there is a difference, the Jag has a classic slalom style outline, cutouts, squarer rails, longer and a more powerful and upright fin - so really much more matched to top end speeds. But the Blast is also no slouch, but will not win in a one on one top end speed battle, it's quick to accelerate, but more of a manoeuvre style free ride board, vs the FreeRace Ray?
