Picton is the focal point for Queen Charlotte Sound. The road/rail ferries provide the access for many people to get to the Sounds.
The harbour is sheltered from any sea caused by E to S to NW winds. Winds from N to NE blow straight in and if strong can make the harbour very lively. For boats unable to get into the marina, the area adjacent to the wharves at the ferry terminal give best all-round shelter.
A fee is payable for use of the wharves in Picton and Port Marlborough officials will collect the dues, either at the ferry terminal or at the town wharves. At the ferry terminal there are toilets, showers and laundry facilities for boat owners.
Water is available from all of the wharves and there are bins for rubbish from boats.
The Picton grocery shops are open 7 days, and longer hours in the summer. Most of them will provide a delivery service to the wharves, if given adequate notice. They will also arrange to deliver stores to any of the regular stops on the various mail boat routes in Queen Charlotte Sound, there is a charge for deliveries via the mail boat.
There are a large number of moorings in the area of the town foreshore and care is necessary navigating here at night.
In SE to S winds yachts under sail are advised to enter or leave the harbour between Kaipupu Point and Mabel Island. This route will more quickly get boats into the main wind stream and avoid calms along the SE shore from the Snout into the harbour.
