Regarding the Community Portal What to Do section. There is a comprehensive post on Reddit that has documented most of the one-off ship cosmetics, including the Banana Sails and much more. The poster has been updating his database with new information, despite the post being very old and buried, so I asked him whether the Wiki could get permission to use some of the images he has gathered.
As to the new sails that are rewarded for Pre-purchasing the tabletop game. RareLtd has provided a screenshot of the sails on the Reddit announcement post. I'll ask them if the Wiki has permissions to use the provided image.
