The Tay has a most attractive estuary, navigable with care all the way up to Perth. Dolphins, seals and many other forms of wildlife and birdlife abound in their respective seasons. Entry can be difficult in easterlies or south-easterlies, and the tide runs strongly at springs, particularly where the channel is confined such as at the bridges.
Dundee has a thriving commercial port, with deep water berths up to 9.6 metres which are capable of accommodating a range of vessels from large crude carriers, through cruise ships and bulk carriers, to small coasters. For minor vessels the lock to Camperdown Dock can be opened on request from 2 hours before high water to high water. This is not recommended for visiting yachts, which should explore the facilities offered by Tayport on the south side of the Tay. There is a range of anchorages, including off the Royal Tay Yacht Club and at Woodhaven or West Newport (west of Anderson's boatyard). There are large vessel anchorages at the Lady Buoys and Balmerino (for Perth).
