    Re: A question about plotting sheets and scale
    From: Dan Hogan

    You need to use another plotting sheet or calculate using one of the
    sailings. My fault, I'll try to keep Departure Points under 60 Nmi in the
    future. I picked this the position off of Chart INT 400, forgetting about the
    scale.
