Round Convoys?

[Sandman_28054]

After a year of not playing GWX 3.0, I recently reloaded it and began playing again.

Seems like this happened once before, but I can't say for sure.

After patroling Grid CF 99, I remember reading some thread about Rockall. Turning north, I decided to cruise up there and see what shake loose.

Convoys typically turn up as Red squares.

Picked up a large convoy. Heading: SE, Sp. 8 knts.

This time it was a Bluecircle.

Turned out this convoy had 8 tankers from small to modern, four Whale Factory Ships, 2 large Merchants, and 4 small merchants.

Here is my list of sinkings:

0000 Grid AM 1 Ship sunk! HMS Acheron (A&B classes), 1350 tons
0008 Grid AM 1 Ship sunk! S.S. Tannadice (Small Tanker), 2051 tons
0010 Grid AM 1 Ship sunk! M/V Stanvac Cape Town (Large Tanker), 9679 tons
0017 Grid AM 1 Ship sunk! M/V L.P. St. Clair (Large Tanker), 9680 tons
0026 Grid AM 1 Ship sunk! S.S. Southern Empress (Whale Factory Ship) (Whale Factory Ship), 12016 tons
0431 Grid AM 1 Ship sunk! S.S. Nicarao (Medium Tanker), 8700 tons
0435 Grid AM 1 Ship sunk! S.S. Janna (Medium Tanker), 8327 tons
0438 Grid AM 1 Ship sunk! S.S. Stirlingshire (Medium Tanker), 8701 tons

Are tanker convoys usually blue?
