A side or C side out ?

I thought I had already sent this, but it hasn't shown up in my bolger
mailbox yet so I'll try again. Sorry if this is a duplicate.

I am working on a single-handed schooner and am curious if there is a
preference in putting the A side or the C side of the plywood planking
faced out ?

I do plan on putting some type of cloth on the outside of the planking,
just in case that makes a difference.

Thanks
