We're freezing up here! I put a hat on the stork in front and he has a blanket too. He still looks cold. 

I've added more iPad navigation programs and started the analysis. My list of features has greatly expanded. Some have amazing capabilities although I find it hard to visualize a situation where I would use all of them. In one, you point your camera at the horizon and the app filled in labels for everything in view such as buoys and ships, right on top of the image you see of the horizon on the iPhone or iPad. I'll plow through the list below but the end date for analysis may be a week away with such a big list. It ought to be interesting at least. Here's the revised list:

They all fit on the iPad!

Navionics USA HD
Navimatics Charts and Tides

I hate to say this, but if there are others I ought to add to the list, please let me know now. By the way, I bought them all, no gifts.
