New US Tides Link added

HI Boaters,
I wanted to put a link up here to US tide charts so it will be easy for you to find.
This way you won't have to tear the boat up on a Sunday when no stores are open searching high and low for that darn tide chart so you can plan your trip home from San Juan Island. Not that I would ever have been in that predicament. There is also a link in the right hand column under "Important Links"
Later all!
