I have a Yakima rack on my van, but I would need a longboard rack for my car on a trip around the U.S. I have seen many soft racks (including the Malone inflatable ones and the FCS Premium Soft Racks), which are popular with surfers. I plan to carry a single longboard 12’6″, 35 lbs. The best longboard rack I’ve used was from Cozy Winters Company. Not sure of the brand but they were significantly better than the FCS or Malone racks. Not as compact though.
