Inflatable roofrack + sea kayak = either badly dented roof or lost boat.
Probably both. I'd encourage you to fit some proper bars, probably Thule,
and Thule J bars or similar. Far superior versions from Karitek or Kayak
Carrier Systems easily available in in UK but not generally available in the
us as far as I know.

How much is your boat worth? Let alone other peoples safety when it comes
off the roof?
