Hi Don,
It was great to see you at the messabout.
I like those booklet charts too. I've been using them on the Chesapeake, just printing them out on regular paper and putting them into plastic sleeves in a 3-ring binder. After the outing, I draw my approximate route and keep the page as a momento. It's not as secure as your method, but I also have a waterproof GMCO chart book for backup. The one thing I don't like about the booklet chart is that the lat/long minutes are only marked on pages that cover the edges of the original paper chart. The few times I've gotten lost down the wrong creek, it was tricky to find my position on the chart from the lat/long on my GPS.
