Futuristic vehicle initially hauled into the sea? (10)

I believe the answer is:

hoverboard

'futuristic vehicle' is the definition.
(I know this)

'initially hauled into the sea?' is the wordplay.
'initially' says to take the initial letters.
'into the sea?' becomes 'overboard' ('man overboard!').
The first letter of 'hauled' is 'h'.
'h'+'overboard'='HOVERBOARD'
