On the eastern side of Shelter Point are the four Boat Harbour surfing beaches (T 1055-1058) which form a near continuous 800 m long sandy high tide beach, divided into four by small protruding rock outcrops and reefs. Boat Harbour Beach (T 1055) commences on the southern side of Shelter Point, with a 50 m wide grassy reserve and car park separating it from the harbour. This is the main swimming and surfing beach for the community and the site of the Boat Harbour Beach Surf Life Saving Club. The 200 m long beach faces northeast into waves averaging over 1 m, which usually break across a 50 m wide surf zone. It curves between the island and a 50 m long rock outcrop with a low gradient high tide beach grading into a 100 m wide low tide bar with rips forming during high wave conditions. The surf life saving club is located behind the centre of the beach, with car parking between the club and the point. The northern end of the beach has a boat ramp, which is used by 4WD to launch off the sandy beach during low waves.
Beach conditions at Boat Harbour depend on the winds and tide. Normal westerly winds produce low waves and least hazardous swimming conditions, however higher waves, particularly accompanying easterlies, can produce 1-2 m waves and strong rips, particularly at low tide. Best swimming is at mid to high tide and clear of the many rocks. At low tide the beach may be over 100 m wide, with many rocks exposed and rips in the surf.
Easterly winds and swell can produce a good beach break which tends to be better at mid to low tide.
