It occurred to me that there's something else about the collision between the Olympic and the Hawke that wasn't addressed; the difference in draught. Hawke, at most, was 24 feet deep into the water but Olympic could get up to 34 feet and 7 inches. That's 10 feet and 7 inches of difference in height. How exactly would that damage the bottom of the ship?The keel was never damaged. The Hawke did not go so deep into the Olympic. Aside from the reports in the article of Mark Chirnside mentioned in the above posted link (post #37) it was also photographed.
The "damaged keel" is a lie made up by Robin Gardiner and Co.
Even if it was damaged it could have been removed, cut off the stern and build a new one as they did with the Suevic bow. H&W had already done that with other ships and even have experience in extending a ship (by adding a new "middle" part).
