[ActiveCaptain]

Absolutely not, just the opposite. I like redundancy, remember? You called this topic, "No reason to buy another guidebook"...

That's the second time you mentioned redundancy with regard to guidebooks. I mean, I'm a fan of redundancy with boating. But the things that I make sure are redundant are the things that raise to a certain critical level - navigation, resources, propulsion, etc. As much as I love ActiveCaptain, I'm not sure if losing the ability to find out whether a marina has clean showers is really something that needs redundancy, does it?

I don't think you're biased against iNavX per se, I think you're biased against anything non ActiveCaptain.

I don't think that's fair or true. I raise specific issues with the products I mention - good and bad. The Navionics product is most surely non-ActiveCaptain and yet I've written a lot of positive things about it. I was just interviewed for another article this afternoon and gave a lot of positive Navionics examples. When Practical Sailor reviewed three products just last month and put iNavX at the bottom - last of the 3 - are they biased too? Is there some unwritten rule here that you're not allowed to say anything negative about iNavX, GPSNavX, or MacENC?

All of this is a bit off-topic. If you'd like to discuss reviews and bias of software, perhaps another thread would be more appropriate.

How about this - if there is a reason to buy another guidebook, do you need to buy a new one? Wouldn't a used guidebook on eBay be just as good? Perusing around eBay finds that 2009 Waterway Guides are selling for about $15 whereas new ones are around $40. I mean, if there's some odd need for marina-data-redundancy, doesn't an older guide fit the bill? Since the data isn't very current anyway, why do you need to spend more money?
