Thanks for the new results!
Could you give an estimate on how long these searches took?
The period 9 stuff ran 3 days to a week each. The 3c/7 runs were a week to two weeks each. The c/7 runs were a couple of days each.
I have other results:
c/4 odd width 13 - 21 ships found
2c/8 odd width 13 - 0 period 8 ships found, 21 period 4 ships found
c/4 odd width 15 - 146 ships found
2c/8 odd width 15 - 1 period 8 ship found, 10 period 4 ships found (still running)
c/4 gutter width 15 - no ships found
2c/8 gutter width 15 - no ships found
c/4 gutter width 17 - 255 ships found
2c/8 gutter width 17 - 1 period 8 ship found, 53 period 4 ships found (still running)
c/4 even width 16 - 2 ships found
2c/8 even width 16 - 0 period 8 ships found, 2 period 4 ships found
Width 15 2c/8 odd ship and width 17 2c/8 gutter ship:

I tried doing an odd symmetric c/6 search at width 19, but I got tired of it after 123 phase (~20 rows) and three weeks and I killed it. Fortunately, I was logging the search tree and I continued the search at width 17 and the following ships showed up:

I also looked through my search armadas and found the following small c/4 ships (54, 55, 57, 58, 69). The 55 and 58 are just tags that I haven't seen before added to previously known ships:
