This bay has long been the venue of the annual New Year’s Regatta, and is located at the entrance to Tuna Bay.
A major wharf and a launching ramp makes this a frequented boating centre.
Large numbers of boats are usually moored at its western side and deep water can be found up until close in to shore.
There is fair holding in the sandy bottom. It is possible to anchor with a stern line to the northern shore, but this is sometimes fairly open and is not recommended in winds from the S sector.
The mooring on the eastern side of the bay belongs to the Mana Cruising Club and Tennyson Inlet Boat Club. It can be used in NW to N to E winds only.
There is a post on the shingle spit, protruding from the point between Penzance and Tuna Bay. This post does not mark the end of the danger and a clearance of at least 100 metres is suggested.
