Agree with rachet-typs straps. I recently bought a pack with two long rachets and two shorter non rachets. I put one long fore and aft from trailor, over hulls to opposite side of trailer. I use the shorter ones to hold each hull down to the trailor. Takes 5 min or less and my H16 is glued to the trailor -rock solid. Travel regularly 2 hrs back-forth without any loosening issues. Good luck
