There are new plans to expand Pwllheli marina 16 months after councillors turned down a £3.8m proposal, BBC Wales has learned.
Opponents feared the plans to almost double the 400-berth marina could dilute the area's language and culture.
But a new plan is being put together by Pwllheli Sailing Club in conjunction with council officers, BBC Radio Cymru's Post Cynta understands.
It involves creating 150 new berths, for visiting sailing vessels only.
Pwllheli is recognised as one of Britain's top sailing venues, along with Weymouth and Largs in Scotland.
But some feel a lack of facilities is preventing it from realising its true potential.
Objectors to the original expansion plan argued that creating 300 extra berths on long-term lets would attract more inward migration.
Some feared an influx would damage the area's language and culture, but others argued that the marina's expansion was vital for the local economy.
The new plan would only allow short-term lets, and is thought to involve building a sailing academy and events centre at the marina.
Plans are understood to be at an early stage and funding for the scheme has yet to be considered.
Gwynedd councillor Michael Sol Owen said: "The pontoons will be used for visiting sailors and also for the championships that we run there.
"That's an awfully important part of the economy now, it brings nearly £2m in every summer and we really haven't got the facilities to run these events."
Gwynedd Council Board members are due to discuss the ideas at the end of the month.
