On the last leg of the journey, the app crashed on the iPhone and will not reload. I suspect a memory use issue.
The slip at Bert Jabins is intimidatingly narrow and challenging. When I initially toured the slip and chose it it looked much wider but I think that was because the adjacent slips were empty. With boats on both sides there's hardly room for a fender. The slip may be undersized for the boat. Not sure but I will ask.
