Hi Alan, I trust you and the family are all well.
At dusk, sitting under the Shark Rock Pier, my daughter and I were trying to compare the length of the longest whale (Blue Whale at 30m) to Shark Rock Pier.
Now, 30m is moerse long, but I cannot trace any reference to how long the Pier is in comparison.
Would you know? Do I think you are an encyclopaedia? (Yes).
Regards
Corinne
Answer: Construction of the 137m long reinforced concrete pier was started in 1998 to save Hobie Beach from erosion.

Shark Rock Pier Hobie Beach – 137 metres in length
The pier makes a stunning platform to watch watersport from – look out for the upcoming Boardwalk Hobie 16 National Championships from 27 to 30 April 2012.
