Canoes are long, heavy, and catch a lot of wind, so simply tying a canoe down with bailing twine on naked crossbars is one way it could end up in pieces on the side of the road. The Thule 819 Portage Canoe Rack features L-shaped brackets that prevent the canoe from sliding side to side due to road and wind forces while the padded, weather resistant bases protect the gunwales from dents and scratches. Heavy duty load straps with rubber buckle covers are included along with a set of bow/stern tie downs for additional stability and security. Ramped edges assist with loading and unloading, but keep in mind, we are still talking about a canoe. For a more effective lift assist, see the Thule 847 Outrigger II. 819 Portage canoe carrier comes with tool free FlipFit brackets that are incredibly easy to use and fit virtually all crossbar systems. Fits Thule Aeroblade and other T-slot style bars with Xadapt 12 T-Track hardware kit (sold separately).
