Everything but the kitchen sink on the roof

Searched everywhere...couldn't find it...and know I'm not the only one that's tried it.

I've got my anklebiter installed, and am getting a solo kayak, and want to also add the stacker on there. can both fit on the fac rac at the same time with bike and boat? I'm a crazy adventure racer needing ideas before making the purchase.

I know...I should plan one activity at a time.

AND...I'm looking at a solo, but might get a tandem kayak. Will that make a diff?

Thanks ahead for the input.

You may not need the stacker. I've just stacked 2 kayaks (of different kinds) one on top of the other with a pool noodle or pipe insulation placed between them and hauled them on the hightway no problems.

A while back, scOoter had posted a pic of his X with a stacked kayak set up.
