Boutique cruise ships and luxury superyachts stretching four times longer than a cricket pitch could soon be parked up on the Gold Coast under a major redevelopment plan.

Berths for boats longer than 80 metres as well as parks, an underwater sculpture garden and a controversial ocean-side cruise ship terminal have been flagged by the Queensland government as development options for The Spit.

Sarastar is three decks and 60 metres of unrestrained Italian flamboyance. Superyachts like it could be seen on the Gold Coast.

The state-owned parkland on the Gold Coast was once earmarked for a $3 billion Chinese-backed casino but is now the focus of a master plan, made public on Saturday.

It details two options for a cruise ship terminal at the current Philip Park site but states the planning process will not decide if that project goes ahead.
