take the oar stands off the bottom raft so that the top raft will sit right on the bottom one? other than that, the only thing i know of is to derig the bottom frame, ride it on the top one, and rerig when you get to the putin. never seen a rack that is made for this, but i'm sure it can be made....
By the waterside I will lay my head.
Listen to the river sing sweet songs to rock my soul.
