Isobel is one of the two boats built in 1988 following a massive fund-raising effort by the class and members of Howth Yacht Club. Like the other boat built that year, Erica, she was initially owned by HYC and was chartered out each year to keen applicants.
Isobel was named after the widow of Jim Anderson after his efforts helped raise the money to build the boats but sadly he died before their launch.
