Abby finds settling into the Tarrant social scene rather a challenge. Tom begins work at the Boat Yard where Avril remains coy about the buyer of his boat. Jan’s mother, Kate, encourages her to accept Ken’s offer of work. A distressed Abby takes some drastic action.

Leo acts like a hero. Jack has reservations about Tom’s approach to the Mermaid Yard and Avril is caught in the crossfire. Abby’s relationship with her mother continues to be a difficult one. Tom and Jan have a frank discussion about the state of their marriage when Jan finds herself preoccupied with her job at Ken Master’s company. Lynne expresses an interest in participating in the impending Fast-Net boat race and Philip Morton is looking for some crewmembers.

Avril and Jack continue to disagree over the future of the Yard and Tom's role in the decision making. Jan offers Ken some business advice over dinner, much to Tom's annoyance. Leo takes a shine to Avril but Abby feels left out in the cold. Kate rescues Jack from a ditch and they have a heart to heart about business and family matters. Lyn and Tom sail the Flying Fish for one last time.

Abby secretly leaves for Southamptom leaving all in Tarrant mystified. Lyn is perturbed by Phil Norton's agenda and blows her chance of crewing for him. Charles Frere shows an interest in developing the marina. Ken uses his knowledge of who really bought the Flying Fish to drive Tom and Jan further apart.

Over dinner with Tom, Avril confesses to buying the Flying Fish. Polly encounters Charles at a gallery opening but does not get the reception she desires. She later admits to Jan that Gerald is not Abby's father. Ken continues to cause friction between Tom and Jan. Charles expresses an interest in purchasing the Mermaid Yard and saving it from financial ruin. When he pays Avril a visit, the true nature of their past relationship emerges. Tom comforts Avril following her unexpected encounter with Charles.

Charles and Ken come to gentleman's agreement about the planned marina. Jack turns to drink when the yard loses the German business contract and the bank threatens to foreclose on on the loan. Charles talks with Avril about purchasing the yard. When Tom wants to re-mortgage their home, Jan turns him down flat. Meanwhile, Ken offers Jan a helping hand and Leo finds Abby. Jack is outraged, yet again, by Tom and Avril's decisions about how to run the yard.

Charles enlists Gerald's help in his plans to develop the marina. Tom and Jan come to a financial agreement even though their marriage is over. Leo is determined to help Abby and her unborn baby. A mysterious man, Richard Shellet, claims to have a genuine claim over the Mermaid Yard. Jan travels to London where she meets fashion photographer Claude Dupont. Lyn has great success in the Fast Net race and Ken naively agrees to go into partnership with Charles.

The legal battle between Jack and Skellet over the Mermaid Yard hots up. Tom adapts his boat designs to appease Jack while Charles and Ken's plans for the marina development forge ahead. Charles seduces Lyn and learns of Tom and Avril's affair. Jan receives a business offer from Claude Dupont and a personal offer from Ken. Kate invests in a racehorse. Polly interferes in her absent daughter's life.

There is descent at the Boat Yard because Tom, Avril and Jack are all too preoccupied elsewhere. Jan and Ken celebrate the opening of their new business venture, the Periplus Boutiquie. Shellet is happy to receive payment from Charles as they await the outcome of the legal action. Tom and Avril get support over his latest design from Relton. Charles and Lyn spend time together but she has doubts about his sincerity. Polly and Abby come to blows with potentially fatal consequences.

Whilst the mermaid celebrated another successful launch, its future hangs in the balance at a London court. The mysterious disappearance of lovelorn Lynne causes panic.

Brittle Polly Urquhart is delighted by the arrival of American stud Orin. Lynne's amnesia leaves her living in a world of strangers and news from France threatens Tarrant's bourgeoning fashion scene.

As leather-clad Leo mourns for the birds, Mr Shellet plots a dangerous revenge. Ken's ambivalence towards Claude's designs enrages dazzling Jan and silver fox Charles puts a scheme in motion.

Ken’s cloak-and-dagger attempts to frighten Leo don’t have the required results. An opinionated visitor forces an impossible decision on Abby and an affectionate gesture from Tom emphasises Jack’s increasing distance from the yard. 

Polly’s revelation leaves fertile Charles in a quandary. Jack’s behaviour causes concern at home and the boatyard, forcing wily Avril into a boardroom decision. 

Oh, happy day! France and Britain are joined in matrimony. Charles’ interests in the Mermaid ruffle feathers in the boardrooms of London and Abby confuses politics with desire. 

Abby is seduced by the icy blue eyes of sexy but dangerous fanatic Curtis Jaeger. Leo and Jan come to blows and Tom is left reeling by Avril’s cold and concrete business heart. 

Darling Jan proves she’s as wonderful a daughter as she is a mother and lover. Charles finally gains control of the boatyard, but is it just business he’s after? What future is there for the Mermaid when tragedy strikes the Lynnette?
