Never played it, but as a child i played a lot of a very similar (i believe) game called Nautic Miles, in which you try to get your convoys across the ocean in the face of various attacks from your enemy. The moves (that i can remember) are to play a convoy card of some value from your hand, face down; to add a miles card to a convoy (scoring it if it reaches 4000 miles); to expose one of your opponent's convoys using a radar card; to stop one of your opponents' convoys using a storm card; to release one of your storm-bound convoys using a fair weather card; to sink one of your opponent's convoys using a mine card (unless they can counter with a minesweeper card); to attack one of your opponent's convoys with a warship card (which they can counter with a stronger warship card, which you can counter with a yet stronger warship card, etc); and some form of air attack, which could be foiled if your opponent had an aircraft shot down card. There was also something about alerts; maybe you had to lay an alert card on a convoy before you could attack it (except with a mine!). How many times did i successfully press an attack, at the expense of multiple cards, only to discover that i had sunk the worthless chalutier? It dates from the '80s, but has rather elegant art deco card designs: https://boardgamegeek.com/image/540087/nautic-miles https://boardgamegeek.com/image/540087/nautic-miles https://paille-editions.com/V2/produit/nautic-miles/ https://paille-editions.com/V2/produit/nautic-miles/
