Glad you like it. I hope you find it useful. As you are from the area, please let me know if you have any feedback. I do have a minor revision coming out (a couple wrong numbers) and add a little bit more on discussing tides. I'm waiting for any more feedback of where my eyes glazed over from looking at it so much.@wetb4igetinthewater Thanks for putting this together and making it available to the public. I found it to be a great supplement to my open water training and what I’ve been able to learn on my own since then.
