I don't think anyone has searched very deeply for these. Keep in mind that in Life for speeds c/6, c/7, and c/8
dragon is the only ship with a search width less than 10.
I ran c/6 w8 u and reran w8 v with qfind. Here are the longest partials:

I suspect that there is a ship at a search width of 9, but it's hard to be sure without running the search, which I don't plan to do.
I did run c/6 w9 a, but the longest partial wasn't very impressive:
Code: Select all
x = 9, y = 39, rule = B36/S23
