The Bible says it was 450' long and 75' wide. It says nothing about the shape, though. I seriously doubt that it had pointed ends. It just needed to be a big box that would float around with God's guidance. No propulsion or guidance needed. Nobody knows, of course, but my guess would be that it looked more like this.
I don't think the Old Testament says anything about feet.
