Port au Choix makes an excellent harbour of refuge. Although the entrance is narrow, it is well buoyed/lit with very prominent leading lights and could be safely entered in most conditions other than strong northerlies. Once inside, the harbour is sheltered from all directions and particularly from the prevailing south westerlies. We sat out a SW gale here very comfortably.
It remains primarily a working fishing port and there are a significant number of wharves all around the bay. The long set of wharves to port after first entering the harbour is not suitable for yachts and is used by the bigger trawlers. The public wharf is at the far south east corner of the bay and has 2 well maintained wooden floating pontoon systems, one either side of the coastguard vessel pontoon. There is normally space for yachts to tie up here amongst the other smaller fishing craft.
In 2016 a set of inner breakwaters was in the process of being constructed to protect the floating pontoons from the short northwesterly fetch across the harbour. Once complete, the all round protection in the inner harbour should be even better.
Ashore there are a couple of cafes serving traditional Newfoundland fare, a drug store, bakery, post office and general store. There is a Foodland supermarket 20 minutes walk outside of town but the choice of food was not appreciably better than that available in the general store in town and may not be worth the walk. Large quantities of fuel can be delivered by truck, or smaller quantities ferried by jerry can from the petrol station in town. Large propane bottles can be exchanged at the Foodland store but if you have the more normal smaller sized propane bottles you will need to go to Port Sander ($15 taxi ride) where they can be refilled at the Esso station.
The harbour master's office is on the main wharf, just to the north of the coastguard station. It has showers, toilets and a launderette. There is a single fresh water hose right outside the office, although you will probably need to tie up outboard of a fishing boat in order to fill up your tanks from it. Electricity is available on the main wharves but a long extension cable is needed to connect from the floating pontoons.
