sort of stretches the reality a bit but there are many different boats that go over and back many different times a day. This is a cut and paste from Wiki

Run by Nusa Lembongan locals there are afternoon trips back to the mainland everyday. The boats are all fast modern and comfortable and take 30-40min to cross. Departing from the beach at around threeish each day the boat then returns to the island at around 4pm, waiting for passengers at the beach in Sanur. There is no need to book many of the local boys or porters on the beach will show you the way.
Public boats depart daily from Sanur beach public wharf (near the Grand Inna Bali Beach Hotel). No same day return. IDR 40,000 one-way at 7-10.30am. They can be a bit sketchy at times and usually very crowded. No same day return. IDR 40,000 one-way. The ride across is approximately 90 minutes. Seas can be rough.
Perama a local transfers-only operator for the budget traveler, without same day return, IDR 70,000 one way, and has a network of connecting bus-links from around Bali. Boat departures daily at 10.30am. The ride across is approximately 90 minutes. The office of Perama Sanur can be found at friendly Warung Pojok in Jalan Hang Tua. Daily Perama buses depart from here to Ubud, Kuta, the airport, Padangbai (for Lombok) and now also Amed.
Scoot Fast Boat, [1] leaves from Sanur too. It operates fast comfortable boats which take you to either Mushroom Bay or Jungutbatu for US$25 return. The tickets can be bought from the Scoot offices next to Dunkin' Donuts, by the Paradise Beach Hotel, or on the beach near the departure point. It takes 30-40 minutes and is probably the most modern scheduled passenger ferry on the route.
