Southampton Water Defence Boom (Hook)

Southampton Water Defence Boom (Hook) (81734)

Easting: 450200
Northing: 103990

Description

To enhance the defense of Southampton the Royal Navy installed a physical barrier called a boom which stretched across the mouth of Southampton Water. The boom was anchored at each end near Calshot Castle and Hook. This replaced a line of old hulks and ships .

There is a 3d model of the constructions at https://skfb.ly/68EHq

Periods

Period: Modern (1901 and later)
Period comments: Defense barriers were in place at various periods in the early part of the 20th century starting with a row of ships & hulks. The cable boom was likely to have been constructed during 1909 though plans were drawn in 1907 (updated in 1911). The guns on the dolphins were decommissioned prior to WW1 due to failings in the design.
