That gives you just enough time to get to Maine and back, and likely no more. If you go Onset to P-town, P-town to Biddeford, Bidderford to say Portland, Portland to say Penobscot Bay,...it's time to turn around, and those are all loooong days. Why bother?

You should try to allow yourself more time, I know how hard that can be.

One thing that we've done several times is I take the boat alone(or with the kids) overnight one way, and my wife follows with the car at a later time(call for an update). You might consider something like that which can give your wife and dog a break. It's an easy 5 hours to Boston from Penobscot Bay over the road.

It's about 150 NM from the CCC to western Penobscot bay, a good area to meet your wife and leave a car(Rockland, Camden, Rockport-free parking...). If you moved at 7 knots, that about 22 hours.

Now you've got some time left to sail and enjoy Maine.

Then there's the likely possibility Larry, you'd have 15 knots of southerly wind coming out of the CCC, for Double Horizon to broad reach at,... 9, 10, 12,...??? knots,....
