Bangor Notice to Mariners

Navigational Special Mark Position. Update

We hereby notify mariners of a small change in position of the four special marks at the corners of the experimental mussel farm site in Conwy Bay. Each special mark is of yellow, St Andrews Cross type (2m), indicating a marine farm/aquaculture. The NE and SW marks are fitted with a yellow light, set to a 5 second flash sequence.
The new positions are:

	DDM WGS84
NW	N 53 18.643	W 3 59.523
NE	N 53 18.688	W 3 59.282
SE	N 53 18.543	W 3 59.205
SW	N 53 18.497	W 3 59.446

The experimental site and system

The experimental site is in an area of open water in Conwy Bay (see figure 1), just to the East of Dutchman bank. It is marked on admiralty charts for aquaculture research.

Within the site are six 150m polysteel longlines. Depending on production state, they may be buoyed with pencil floats, or they may be invisible; using near-surface submersible floats.

Please be cautious when navigating near to the site

Mariners are requested to give the installation and the buoys by which it is marked a wide berth. The buoys have drogues attached that trail beneath them in the water.
