Baie Comeau is primarily a commercial harbour with a bulk carrier terminal at the head of the bay and a conventional mole harbour a little further out. The yacht harbour is just to the south of the latter. Once inside the yacht basin depths are adequate for any normal sailing yacht  but the entrance channel is quite constrained and surrounded by shoal water. The marina staff  advice that a vessel drawing 2.0 m or more should not attempt to enter a couple of hours either side of low water. 

Baie Comeau is convenient  if you need to refuel, take on water, re-provision or get internet access, but if you just want a place to stop for the night and the wind is not blowing too hard from the south, then Anse St Pancrace, just 5 miles to the NE is an altogether more attractive stop.
