Most of us would instinctively roll charts so the chart is "inside" the rollup. But if I roll the chart so the printed part is on the outside, then when I unroll it any tendency to "spring" would be downwards, not upwards.
Let's also remember that
most charts are purchased (or at least were, given that ships are now allowed to use commercial-grade chartplotters) by the commercial maritime industry. Ships have adequate-sized chart tables. I personally think it's silly for a sub-30 foot boat to have a chart table; there just ain't enough room. But I suspect that there are "check off the list of features" buyers and builders that feel a uselessly tiny table bests none at all.

Greg makes a good point, those chart books rarely strike the real joy and pleasure of skirting across the sheet with a parallel or roller rule, but look at the Weem and Plath Nav board, it is specifically designed for those NV Chart type or the Mapquest series.But I also like the PVC method of stowing the large charts. And to keep the chart from "springing" back God gave us weights, and I have 4 cast iron painted white whales weighing a good 1/2lb each to hold the rolls at bay.What diametre PVC pipe would you need or wnat to use for 10 to 20 charts? I would keep them numerically ordered, and label the pipe for the numbers and titles, and of course PVC capped is better than Kraft tubes aboard a boat every time.I saw a PVC pipe specifically labeled for charts, I think either Celestaire or Weem and Plath sells it.
