As you can see by my track

I did a quick check on my GPS and noticed I was very close to max ebb for the Race so figured I would turn around. The wind was very good about 15 knots.

I figured with that much current against me I would only make a couple knots overground.

As you can see I was going 4 to 5 knots.

Any explanation as to why.

The only thing I can thing of unless you see a dumb mistake is that I was just out of the current by a few hundred yards.

It would seem that anyplace in that area would have significant current though so I'm perplexed.
Do you use Eldridge? The answer to your question may lie in Eldridge. The maps with current directions and speed there may help.

More importantly, as others have mentioned:
Your angle vs the (actual) current
the fact that these predictions are educated guesses and not pure science
local knowledge

I sail this area all the time and have been for years. If you are trying to figure out why the current was not doing exactly what it was supposed to do when it was supposed to do it, my advice to you would be; Good luck

When it's nearly an hour past "predicted slack" and the nuns and cans are still healing and straining against a current that should be with you by now.... welcome to New England.
