I have a finished Kaholo and I see no problem carrying it on the side, nor does my Yakama dealer rack guru. It's a tough board. I think mounting it on edge is okay. Windage from a side view board might be a problem in a crosswind. I may try it in the future since my daughter, board user, wants to rack two boards  - on a neon = dinky car. My choice is stack them or go side by side vertical - Yakama frowns on two side by side flat boards that size - 14' - not to mention two side by side won't fit on dinky car rack.

I would only carry Kaholo on edge between two kayaks so wind shouldn't be a big factor. I would carry it flat if not taking with two kayaks. I drive a Forester so haven't have any issuses with wind yet.

Thanks for input
