Mine are 6 feet long and each comes apart into 2 sections. They are
light weight and easily fit into the lazarette. I got them at WM. The
locking mechanism is usually torqued in the store by customers
attempting to take them apart without understanding how they work.
Have the sales people fix the locking mechanism and test it before
leaving the store. If you know how to do it, the oars come apart
easily and lock securely.
