The carrier must be mounted usual, simple and fast as Thule. The design allows a very secure and safe transport of the boat. Especially when several boats transported on the roof to the possibility of Abklappens the vertical bracket for loading other boats is enormously helpful and important for me, as the argument of fuel saving, because if I do not need the support, I mount them off completely. The tension belts supplied with the protection to the buckle are also great, now I do not want other more. Highly recommended!
