Giant Jacks? Who Knows The Official Name?

The cycling artist, Tina Mammoser has got in touch and is hoping our readers might be able to help with a query.

rightWhilst on the Wight recently (sponsored by the excellent Vintage Vacations), as part of an English Coast paintings project, Tina fell in love with the concrete sea defences that run along the coast near Wheelers Bay.

Their interesting shape has inspired lots of sketching and she’s even sculpted clay versions of what we refer to as ‘giant jacks’.

Given that they’ll feature in her project, Tina wondered whether our readers knew what the official term was for these shapes.

Can anyone help? If you happen to know, perhaps you could leave a comment on this posting.
