    The only app I could find in the store with detailed charts of Hong Kong, so obv a major plus for that. I love the usability of the interface, they have a very good guide to get you going and then from there you can get the hang of it pretty easy. As other reviewer stated, I would like auto routing as manually doing it can be pretty tedious. That said, you can copy routes and adjust from those, plus a lot of nav apps don't do auto routing well because of depth and other restrictions fouling it up. The charts are outstanding, the level of detail and quality of information is top notch. I actually like this app better than my Garmin hardware chartplotter that I use on a different vessel and this app was a fraction of the price. Don't be deterred by the negative reviews on here. I think the developer got it right in terms of offering balance between features you may or may not need.

    I have 35 routes around Savannah, Georgia which I use on a motor boat at 25 knots. Easy to follow. I just completed a 900 nm passage from Tampa, FL to Savannah, offshore in the Gulf and Atlantic. All the planning and onboard navigation was done on an iPad with iSailor (with considerable prudent backup that was unneeded). This included three unanticipated ports of call which required rerouting while at sea. Excellent accuracy, even in tight quarters. (However, pay attention to expected GOS accuracy). The skipper said “the nav job was fantastic.” There is a reasonable learning curve to iSailor because this is a sophisticated, prosumer-level product. There are numerous app-purchase chart packs and instrumentation add-ones. If you just want to go around the lake, the app is overkill.

    We purchased this application since it suppose to work well with our Vesper 8000 AIS we just purchased before we head to the Bahamas for the winter. We purchased the maps for the Bahamas also with the apps and there are areas that we cruise in the Exumas that are data just note (Dredging 2 meters)....these are area we sail through and use the Garmin Blue Water and Explorer Chartbooks to seeing this blank area on the apps made me wonder if there were anymore out there. I contacted the APP maker and they validated the omission and said it would be corrected in the next release but no specific date when that would be. So overall....I guess it's a decent apps but recommend you have backup valid charts or applications.
