Okay - I have a much clearer idea what happened thank you
On a *completely* different topic: I've read a lot of books about naval operations during the age of sail (notably, the Patrick O'Brian series, although I still have a few more to finish). This means although Gamil doesn't know much about sailing and ships, I do a fair bit. *however*
1: This is knowledge from reading well-researched novels and books. I have next to no *personal* sailing experience, and that counts for a lot.
2: The workings of fairly advanced sailing ships on a well ordered navy may be quite different than a medieval, fantasy ship. The tech and culture are just not the same.
3: I hope that this partial knowledge can be of help to the GM and not a disruptive know-it all
So all this to say that despite Pyrlig's mistaken impression, smiths were commonly found on sailing ships with mini-forges, to maintain the weapons and craft various tools and useful metal objects. Of course, the Medusa may or may not have such facilities (although Gamil does have some tools).
