Well, we ended up with the Nautly Dinghy Ramp XL. Happy with it. Seems well made and was very easy to install.
I type this sitting on the baot, ready to leave tomorrow AM. Very excited about the trip, and the family is looking forward.
Naturally, I did not get the right chip nor the cruising guide. I did pick up the paper charts, however. I now have a chip that will take me up the the locks, and hope to be able to buy teh chip I need up river, as well as the cruising guide. If I can not find the chip, I will use the paper charts.
Thanks to everyone who provided input. We will be playing it by ear, and staying out on the hook a lot. I will try to post every day here.
Tomorrow looks to be rainy and slow going, but w/e.
