Those old boats might be big, but they're not exactly safe or even that heavy. Here's an interesting crash test comparing one to a modern vehicle. https://www.youtube.com/watch?v=C_r5UJrxcck https://www.youtube.com/watch?v=C_r5UJrxcck Both of those cars weigh about 3,500lbs. Now swap in a 5,000lbs Tesla, or that new 9,000lbs Hummer EV. That big old car will be nothing but a pile of twisted metal. In short, I don't think you can compare large cars of the past to ones that exist today.
