I guessed 'k' meant knots (kts), but didn't work out that the 'c' was meant to indicate cables (ca).
Is the area around the submarine barrier covered by the 10kt speed limit? - I can't recall offhand what still constitutes the Portsmouth Harbour limits

This puts the submarine barrier gap and Boyne SHB outside the 10kt limit
