Yes Like I said I have the tide tables for my area. I will leave with the tide and return with the tide. What my question is how bad they effect is off shore? I understand the river and have sailed them 45 times in the last 2 years. Just need some advise for the off shore tide conditions. I see high and lows and when they are predicted , But along the beach to 10 miles out? does low tide go south and high go north? Does it go straight out to the east? Dumb question I know. Still learning this stuff. Sorry.
