Uncle Peak ,

Getting better all the time!

I’ve been playing around with the beta versions for about a month or so now. Since my boat is out of the water, I’ve been “cruising” up and down the ICW using the Waterway Guide, checking Ditch Smartpath against Bob423 nav alerts. Amazing correlations. This will be a great tool to have on board next summer when I need some extra assurance.


Great job highlighting difficult to navigate areas

Enhances the MLLW data found on navigation charts to also include the paths most traveled by those most knowledgeable about the local waterways. The Mianus River in Greenwich, for example, practically becomes a beach at low tide and requires practical knowledge to safely navigate. This app does a great job of showing the narrow route to take.

Brilliant - Surprised this is only available now

Great concept and very intuitive interface. This fills a void in traditional navigation products. In a data-driven society, this is the art of the possible and opens the door for operators to explore new waterways!
