Sailing things right

My sister today came to me with the question about the process for automated retouche. There are plenty of SaaS about that on the market but I decided to give a shot with any local model I'll find.
And that is a result of «Here's a reference photo, there is a photo to edit. Take color palette baseline from first and apply to the second. Touch nothing else, only color curves».

The left one was an image to edit and the right one — is the outcome.
