FORT LAUDERDALE — Say your neighbor has a yacht so big that it dwarfs the dock behind his home. Do you call the city to complain? Michael Meldeau did. It wound up getting him sued by one Steven Howell, owner of the yacht. The two men live on Delmar Place in Fort Lauderdale’s upscale Las Olas Isles, just north of Las Olas and west of the Intracoastal. The yearslong feud isn’t your run-of-the-mill neighborhood dispute.
