We haven't used BB yet. We actually haven't made a trip down in almost 3 years now. But when I first saw it, I didn't think it was a big deal. Here in New England, it seems many marinas use dockwa. Seems to work well. Major difference is you can book further in advance, but it is also a lot more expensive. I wasn't really sure why a whole new method/app needed to be created for this when others existed, but I also didn't see it should be a big deal. I know if we wanted to take a mooring, I'd much rather know we have one waiting then get there to not find one. Especially in a spot like cooper.
