I will be sailing out from the Texas and hanging a left - need coastal nav.

Laura bought some stuff called "Map Seal" used by surveyors to water proof papers for use in the field. Google Map Seal and you'll find it.

Thanks, CJ.  I used to use that (or something very similar, but I think that's it) on my 7.5 Minute Topos when I carried them bushwacking, but could not remember the name of it.  I seem to remember it stank.

Map Seal makes sense...I should be able to remember that....

Not all inkjet printers use water soluble inks... and many will do much larger sizes than LTR size.  I've printed charts out on an Epson 4000 series printer and used a plastic-based "paper" for them and they're both waterproof and pretty tear resistant.  I did it as an experiment to see how well it'd work.

True, but don't that plastic paper cost a BUNCH more than your garden variety 8.5 x 11 from Office Depot?   

Also, I was under the impression that an inkjet printer that would do nautical chart sized paper was pretty durn pricey, and are thus not generally accessible to most of us in our homes.  I've got a fairly high dollar business grade Deskjet (nearly $500 a few years ago), and it maxes at 8.5 inches wide.  It will handle LONGER paper, but not wider.

My method is a cost cutting measure, nothing more, nothing less.

Found the map seal at Safety Central for 6.97 per 8 oz --that sound bout right?

I've used a $0.99 can of clear spray paint from the hardware department to do the same thing. I don't know if it works better or worse by much, but unless your stuff gets *soaked*, it works about the same. :)

The paper was leftover from a printing job my friend's company did, and he had parent size sheet stock, which is rather large.  The large format printers are fairly pricey, but I know a lot of pro photographers who own them, so can get the use of one rather easily.  I have an Epson that will do 13" x 19" paper in any case.
