How to unlock the Hoverboard achievement in Shaun White Skateboarding - Definitive Guide
Turn around, grind the next shaping rail to the cinema roof and save your position.
Then grind the shaping rail off this roof. This is a long grind (170m+) so reload your position so they are actual grindrails and unlock the achievement.
The balance meter I told you to turn on under the settings helps here as well. There are honestly 100 places you could do this. Just find a long rail and grind it. Notice it says "without touching the ground” that means you can do tricks in between grinds if you need to.
In the options menu make sure to turn the “Balance Meter” on. This will make it easy to keep your balance on long grinds. I unlocked this during the mission where you have to knock out the Ministry loudspeakers. Start out on the rail that goes on top of the white box truck (located in the main square area). From that point you should be able to sgrind onto several different rails. The achievement should unlock at the end of the rail, and you must land safely. This achievement can also be completed in several spots later in the story.
