I believe it's set up here on iboats that only the mod's can "delete" the post or thread.....If you still see the edit button icon, you could remove the contents of the post and title too and maybe say please delete in the title so one of sees it.
Or best/quickest way would be to either report the post or topic.... Or of course in your case you could link it here too.

But that mentioned, I'll probably find it right after posting this message.
Edit: Found it and you should of received an "alert" message saying the post was removed from sight....As an example for others reading this, Here the link to the removed post as it should go to nothing now,
