Loch Fyne Boom

Recent Page Trail:

The Loch Fyne Boom was a World War II anti-submarine defence which protected the upper reaches of Loch Fyne, a sea loch with a considerable inland reach.

Reports only identify the eastern end of the boom, just west of Otter Ferry, where surviving remains on the site show the location of the boom depot, where the anti-submarine net and other components would have been stored when not deployed. The location of the western end of the boom on the opposite shore of the loch, has not been referred to in any reports or accounts of the boom, but is believed to have lain south of West Otter Ferry.

The depot site lies along the beach to the west of Otter Ferry, and is marked by a single concrete building measuring 4 m x 4.6 m, and is single story but has stairs leading to the roof. The end facing the shore is completely open, while the opposite end features a large aperture at ceiling level. It has been suggested that this was an engine room, supplying power to the boom, but this seems unlikely as there no engine mounting bases have been reported on the floor, which appears to be smooth. More likely is that the building was some sort of store related to the boom.

A row of small concrete blocks leads to the water, and a number of metal rails remain on the shore, purpose unknown.


There may be no connection, but the depot is located to the east of a beacon which marks the extent of an oitir or spit of sand and mud between the two features. Had the boom been anchored to the ground where the beacon is sited, then it could have less than half the length and weight otherwise needed to bridge the entrance to the loch, as no submarine or vessel could have passed the the shallow waters east of the beacon.

Western anchorage

No documented references have been have been discovered relating to the western anchorage of the boom, however it has been noted that OS mapping of the shore area opposite the depot, and in line with the beacon, has a site or building marked "Anchorage". The site is not described, and has not been visited. It is also relatively far inland. With no further information, it is not possible to state whether or not this feature is related to the boom. Any local knowledge would be appreciated.
