That makes sense. On my little O'Day Day Sailer, I had our local sailmaker cut down an old jib to use as a heavy-weather sail. He suggested mounting it off the deck (essentially at the same height as when it was full, except now the bottom 25% was missing). His argument was that this is where storm jibs usually fly, the expectation being that at deck level in a storm, the sail could be hit by a breaking wave. Also, by keeping the peak at the same height, the standard turning blocks for the sheets were more or less still in the right position. After trying it a couple of times, I mounted the tack right to the stemhead, just like the working jib. The sail trimmed a lot better, although I did have to provide new turning blocks forward and inboard on the cabin top.
