Yep, Gainiac uses the same tactics that I use. It works wonders for finding shipping in the pre-radar era. One thing it helps to offset, is the early war faulty torpedoes. During that era, I tend to stay away from smaller, shallower draft ships that are less than 15ft from the waterline to the keel. You will still have problems with fish running too deep, but most will hit home if the ship is a deep runner. And don't waste your early torpedoes on any warships smaller than a heavy cruiser, and it needs to be fairly calm for the sea-state. Nothing over 6mps. I wish the wind was in knots. Watching Deadliest Catch, the CG still gives the weather reports with wind speeds in knots, and mph.
