Interestingly the saftey regulations also contributed to the sinking of SS Eastland (your 2nd link):

> During 1915, the new federal Seamen's Act had been passed because of the RMS Titanic disaster three years earlier. The law required retrofitting of a complete set of lifeboats on Eastland, as on many other passenger vessels.[7] This additional weight may have made Eastland more dangerous by making it even more top-heavy. Some argued that other Great Lakes ships would suffer from the same problem.[7] Nonetheless, it was signed into law by President Woodrow Wilson.

More recently in the Thames, the Marchioness.
