I KNOW I saw it on Lit, but now I can't find it. It was called "Lusty Lessons" (that exact title), about an idle-rich yachtsman who rescues a shipwrecked Russian woman.
If you know the title, you can find the story through the story search. If that fails (and you're sure you know the title) then the story is gone. In that case, you can often find the story on the wayback machine (TWBM). To do so, construct the URL by changing the "ending part" of an existing story URL: lowercase the title, remove all punctuation, and replace spaces with hyphens:
Paste this into the search bar of TWBM. When I do this, I see a story with this title by SpiceyAngel that mentions a yacht in the first line, so probably your story.
AFAIK, this is the only hope for reading a story that has been pulled from LE. It often works, but not always.
BTW, I'm not allowed to past a URL to TWBM (if the moderator sees the post, he will delete the message). DM me if the above is not clear.
BTW, very often, you have to do more, because the story will have something after the title (a part, chapter, number, etc.). In that case, TWBM will report that the URL is not archived: "Hrm. Wayback Machine has not archived that URL. Click here to search for all archived pages under <URL>"
Click on that link to find all URLs beginning with that string. (This "show all urls" feature does not always work, you may have to try a couple times.)
