I have never sailed on the left coast so I don't know what the
chartbooks are like, but...
One of the chart books that I have for the Chesapeake is waterproof.
They have a kind of plastic page. I try to keep it dry certainly, but
if it gets wet it's not a big problem.
The chartbook that I have for the Maryland Chesapeake fits into one of
those plastic zippered sleeves. I do the same for any paper charts
that I use, folded so that they fit and show the area we are sailing
in. They come in various sizes. If I had a wet cockpit, I might use
one of them for a chartbook.
We also have a completely enclosed cockpit so stuff doesn't usually
get wet. (center cockpit) I've never really had the chartbooks get
that wet, and if they do, I separate the pages while they are wet to
dry them in the same way you would do with paper charts or any kind of
a book. Just be sure the air can get to both sides of the pages.
(This may require some thought.)
