Thank you for the chance to try your "unfinished" simulation. It was easy to DL and install. The graphics and sound were good and better and than I expected. The mouse, keyboard and hud worked fine too. The "Instructions" were helpful and adequate to get started playing.
The "Painted Ocean" seems well-researched, and had me reaching for my copy of John Harland's "Seamanship: In the Age of Sail". I sincerely hope you find the time to return to it.
I would like to volunteer with any help I can provide . I do have small boat sailing experience, and sci knowledge of C++ (but not game or sim programming per-say) No experience with Unity but willing to learn.
