Just a reminder to be careful when using the Thule Sup Taxi. Yes it is very fast and it locks so that is great but PLEASE put an extra regular strap on the board as well. They have been known to fail and it just happened to somebody we know recently. They were only driving a 1/4 mile from their house and only going 30mph. Wind caught it and sheered the spring/locking mechanism and his 14′ board flew in the air like a football. Thankfully nobody was behind him so nobody got hurt but they could have. Please take extra precautions and never trust the thule sup taxi alone.
