That is the whole problem.
I was very surprised to make that speed against what I expected to be a strong ebb current.

This is a 24' boat that probably can only do 6 in perfect conditions.

Maybe it is as simple as that. I had perfect conditions and was making 6 through the water and 3 over ground.
That may be the answer.
