Shipwrecked is the 13th episode in Season 1 of H2O: Just Add Water.


When the mysterious old woman's boat and home is declared unseaworthy Emma invites her over to stay. Zane gets trapped on the sinking boat and Emma saves him but he sees her tail...


At the local boat yard, Emma finally meets the mysterious old woman who has been following Cleo around; Miss Chatham. And she finds her at just the right time, as Miss Chatham has an argument with Zane about an accident involving her houseboat ("Lorelei") and his jet ski, and then collapses from a heart attack. As she is taken away in an ambulance, Zane hears her muttering to Emma that she needs to protect her ‘treasure'. Later, Emma invites the fragile Miss Chatham to stay with her, and she, Cleo and Rikki get to know her better. But upon hearing that she has been evicted from the boat yard, Miss Chatham sets off in the Lorelei before it can be taken away from her but she accidentally damages Zane's Jet Ski. Zane chases after her in his Zodiac pontoon boat, catches up with the Lorelei near Mako Island, and boards the Lorelei. He demands compensation for his damaged jet ski, but Miss Chatham passes out with another heart attack. Emma and Lewis arrive just in time to help Miss Chatham and take her to seek medical care on Lewis' boat. Zane stays aboard the Lorelei, searching for the treasure. Kerosene from a lamp ignites on the Lorelei's engine, and the boat begins to sink, trapping Zane. Emma is forced to dive down to the sinking boat in order to save Zane, and risks him discovering that she is a mermaid, but he just glimpses her tail before he passes out. Emma returns Miss Chatham's "treasure" to her, and it turns out to be a locket (identical to Cleo's locket), containing a picture of three teenage girls; herself and her friends Julia and Gracie, who were all mermaids back in the 1950s (Cleo's locket belonged to Miss Chatham's friend Gracie). 


  • Emma appears to drink from the glass that Mrs. Chatham gave her, but she doesn't actually drink anything.
  • The Sea Monster storyline is continued on for the rest of the series.

Lewis: (about Miss Chatham) Some people say she's a witch.

Miss Chatham: They're just after my treasure!

Zane: You are a disgrace to this port! You left a scratch on my boat!
