Awesome. A book that does exactly what I had planned to homebrew for my campaign. It takes the ship combat system from Starfinder and converts it to Pathfinder 2e. It even expands a lot on the idea of Naval combat and roleplay. I plan to include the book in my recomended ones to pickup when I finish my setting for PF2e (that's the first 3rd party book to make the list.) I also thought about converting the Skull & Shackles Adventure Path to 2e. This will make it much easier.
