Net laying ship

Nets could be laid around an individual ship at anchor, or harbor entrances or dry docks, or other anchorages.

As World War II progressed, net layers were pressed into a variety of additional roles including salvage, troop and cargo transport, buoy maintenance, and service as tugboats.

Orange anticipated the construction of a large anchorage in Lahaina Roads between the islands of Maui, Lānaʻi, and Molokaʻi.

Construction would consist of massive nets and minefields to protect the anchored ships.

Net layers were eventually made redundant by advances in underwater detection technology.

The United Kingdom and British Commonwealth referred to net laying ship as “boom defence vessel".
