Curious how tiring it is to sail near land, but sailing on the ocean for weeks won’t tire me out as severely.
Here time is a serious factor, time to get to an anchorage: before the tide turns (fighting current is a losing game), before dark (too many dangers in the water, traffic, dead heads, reefs, crab traps), etc.
Land and atmospheric disturbances also moves wind around in unexpected ways.
I'm with you on "too many dangers past dark". I constantly get caught out after dark for one reason or another and invariably the minute the bottom of the sun is touching the horizon line is the minute not a single thing about being out is fun anymore.
