The Stacker is a steel post with a non-scratch coating that lets you stand kayaks on edge against it, fitting more boats in less roof width. It folds down when not in use and installs or comes off quickly. Straps for one kayak are included.

KayakDIY take: Stacking boats on edge is the most roof-efficient way to bring the whole crew’s kayaks. For more gear ideas, see my fishing kayak accessories guide.
