This weekend the local HMGS-South group played a Russo-Japanese War naval battle based on the Battle of Tsushima. In order to make the game more balanced, the Russian ships were not handicapped to reflect their historical performance.
Visibility 14,000 yards. Wind SW at 14 knots. Seastate 3
Status at the end of the game: tsus2 io
Damage output file: tsus2 out
Plot of ship movements:
0 to 30 minutes tsus2 plot 0-30
30 to 60 minutes tsus2 plot 30-60
60 to 90 minutes tsus2 plot 60-90
Computer code (described here)
We called the game after about 4.5 hours of play (90 minutes of game time). The damage was fairly even at that point. The Russian battleships were low on main gun ammunition and several were completely out, so their ability to continue the fight was limited.

My favorite naval war though a lopsided battle – even with your balances thrown in.
