Lifeboats of ships from the second half of the nineteenth century
As for the positioning of the tarpaulin, I took a look around and got an idea, but I still have a big doubt.
Usually when the images don't provide details (even when enlarged) I reason logically: I think about how the thing should actually work.
Now, for fixing the tarpaulin, it's easy: a rope can pass under the edge (horizontally) and prevent the cover from flying away. Or a rope passing through the various rings and under the hull (zigzag) blocks the tarpaulin to the hull.
What I don't understand is how they made the two pulley blocks come out of the tarpaulin. I don't think it was punctured because water would have gotten in (and then it would have been impossible to remove the tarpaulin), perhaps there was a cut and a fold on the tarpaulin where the two blocks were.
Does anyone have a solution?
