Here you will find a few surfboard racks that are avalable for your vehicle and for you home. Your surfboard will last alot longer if it's stored inside, out of the sun and weather.
For your Vehicle (Multi-Purpose)
These are the best racks you can buy. They are very fleable and can be used for many different sport. You purchase the mounts ant the cross bars to fit your vehicle. You Can the purchase accessories to carry just about anything! (Surfboards, Skis, Snowboards, Kayaks.......) They are, however expensive and you need to purchase the mounts specifically for the Make, Model and Year of your vehicle.
Your going to need to put your surfboard somewhere. Leave it on the floor and it will get run over! Leave it out side and the weather will wipe it out in no time or it will get stolen! Get a rack...it's worth the few bucks. (Or, make your own, I did. Some chain, 1-1/4" emt and pipe insulation with screw eyes to hang from my ceiling. Just be sure your ceiling is high enough and the rack won't interfere with the garage door.)
