The best thing about this software is that it syncs in real time, so as soon as you enter one of your boats into the database to be towed, it will show up right away when pulling up another boat's information.
It does not have an auto update function like other towage apps do, which is kind of annoying sometimes, but also makes it important that you go back and check often. I am using it for my personal business at home (towing from our dock), but would definitely use if for commercial purposes too! Being able to track multiple vessels all within one app really helps me keep things organized.
