Siege of Jerusalem (Avalon Hill)
and
Sonar Sub Hunt (Mattel)
Forty years ago a friend won a “Titanic” board game in a Chinese auction in school; the board was cut across the middle with the attached shape of a boat across the middle. With each turn the boat pivoted a little (it was pinned in the center); it gradually slipped under the waves (actually turning upside down, because of how the middle piece rotated). The object of the game was to rescue travelers from staterooms, then get to a lifeboat station. IIRC, you had to get a box of food and a cas of water as well.
When I was young we somehow came into possession of some old second-hand board games that I’ve never seen anywhere else; “Hit the Beach” (Marines storming a Pacific island, with Japanese bunkers as obstacles), “Fighter-Bomber” (I remember this had plastic planes, but I don’t remember the details), and a Civil War game where the pieces were infantry, cavalry, and artillery (you could move more quickly along rail lines).
One of my favorite games was “Survive!”, where you had to get off a sinking island (I believe a volcano was erupting); the sand pieces went first, followed by the woods, and finally the mountains. You had to fill your boat with survivors and get to a corner; eruptions, whales (which would overturn your lifeboat), and sharks (which would kill swimmers in the water) were obstacles.
Ah, memories...
I also had Radar Search from Ideal. It used electric probes and a turnable radar screen to find your opponent on a reverse board.
