Check out the Maptech Waterproof Chart books too. They are a manageable size and mark marinas, ramps, etc.

Just wipe'm off after a day on the water. Maptech also makes an "Embassy Guide" that has marina info and charts of the approaches to the marina's and has aerial photos of inlets and marinas that I really like, adds a little more detail that I find helpful. On their web page you can plug in an address near the waterfront to get a map and then click on the "Nav Photo" tab to get a satellite photo too.
