Emergency hull repairs while at sea

Post by Fatboy Coxy » Tue Nov 03, 2020 10:30 pm

Hi all, certainly in Nelsons time, and possibly throughout the years of sail, emergency hull repairs could and were undertaken while at sea, by fothering. This was the practice of wrapping a sail around the bottom of the hull, being fastened on either side of the ship, hoping the pressure of water trying to get into the hole would push the sail in, providing a decent plug. Come the 20th century and the demise of sail, was there anything similar to effect emergency hull repairs to warships, to ‘get them home’.

You could put a mattress against a smallish hole and brace it. Standard test to see if it would hold was to get a beefy dude to swing from the overhead an hit it with both feet. This is good information up to 197something when my ship was doing training at Gitmo.

For more robust bracing look at the pictures of ships who lost their bows in a collision.

Clearly a credit to the ships architect and builders for the construction of a ship so well compartmented.

I wonder how much spare timber might be carried by a ship for emergency bracing, and just how low and accessible it might be stored in a ship. Back in the days of the wooden ships, they must have carried a lot, but by the 20th century?

In anticipation of such events as illustrated in my last post the outfitting parties would have tucked timber wherever it would fit. I was on USS MacDonough when we were in Gitmo for training. She had just come out of the yards and one of things done during a yard period is to check that we have everything we're supposed to have. I helped load 4x4 and 8x8 wood at one point, stashing it in the overhead piping when we could find a spot. It would take some exploration to find out how much was considered "minimum load out" for that item.
