The Navionics Charts look like a good deal if you are not in the USA where the NOAA charts are free and totally up to date. The other problem with Navionics is that Apple are highly likely to improve the iphone later this year. (The current battery life when using GPS is rubbish.) You will not be able to transfer any purchased charts to another iphone, any iphone, so if your current iphone should break for any reason, you are up the creek without your paddle! But they do look nice.....
