Notice to Mariners

Least Depths in Lochboisdale Harbour

NtM 03-2019

Mariners are warned that recent surveys revealed the following least depths within the breakwaters of Lochboisdale & Gasay Harbour, more details are shown on the attached Harbour Depth Survey.

Eastern Breakwater

A shoal, comprising compacted stone with least depths of 3.6 metres below chart datum, extends 55 metres from the eastern breakwater wall along a line running south south westwards from the traffic light signal.

In effect this gives a least depth of 3.6 metres below chart datum to vessels approaching or departing the Fish Pier.

If necessary, owing to insufficient height of tide or draught, this shoal may be avoided by

navigating as close as is safe and practicable in the prevailing weather conditions to the northern pontoon.

A depth of 5 metres below chart datum is available all along the Fish Pier.

Between the Pontoons

A least depth of 2.8 metres below chart datum exists midway along a line joining the ends of the two main pontoons.

Dome-shaped rock

A spot least depth of 1.4 metres is presented by a dome-shaped rock located 12.5 metres south south west from the end of the southern pontoon.

Mariners are not to access the berths on the south side of the southernmost pontoon without permission from the Harbourmaster.

Those vessels permitted by the Harbourmaster to use these berths may avoid this rock by erring their navigation as close as is safe and practicable in the prevailing weather conditions to the southern pontoon.

Lochboisdale Harbour will man and operate the breakwater Red traffic lights (3FR) during the times listed above when large vessels (defined here as any vessel with a draught greater than 3m and or 20m in length and including all RO-RO Ferries transiting the North Gasay channel.

This procedure is in place to allow more stringent control over vessel movements during the times highlighted in the LHA Navigational risk assessments. Whilst these procedures should be adopted by all vessels operating in the Lochboisdale Harbour area, it is important that a proper lookout is maintained, that the vessel is proceeding at a safe speed and that sound seamanship is demonstrated by all mariners. This NtM does not relieve the vessel Skippers/Masters their obligation to check the Channel is clear, prior to entering it.
