Thought this may be of interest for discussion re sailing inlets etc where fresh and salt water combine or are at one extreme or the other... is it a factor after storm surge, heavy run off... or a minimal impact as long as it's blowing it's ring off and the water is flat.

I think we all have days at Sandy Point where we all hit a wall on certain days, maybe it's just another component amongst the many we manage or go up against where we don't go as fast as we expect on average.

This effect can be important for displacement hulls but is of little relevance for high speed planning boards.

You are always going to go faster in salt water because you float higher, have you ever noticed its easier to swim in the ocean than in a fresh water pool.

That is why we wait until the fresh water has evaporated off the top at LG!

But denser water allows the use of a much smaller fin and board.

The big question? Which is better for best speeds?

From the evidence so far, I suggest that the denser water has the edge.
