It's really important you secure your boat at the front and back of your car. You need to fix bow and stern lines, probably using the front and rear screw-in towing eyes if you have them on the car. Some kayak and boat carriers come supplied with these straps. We also have sets of straps available that are perfect for the job and are really easy to use. Yakima make some excellent Bow/Stern tie down straps and Thule makes the QuickDraw 838 . These straps usually attach to the front and rear screw-in towing eyes but if you don’t have these on your car you will need to attach them somewhere else instead. You could always use the ‘Hood Anchor’ if you don’t have towing loops on the vehicle. Hood Anchors secure under the bonnet or the boot.
