A note from the owner..
"Our Adventure with Paradise
We bought Paradise in 2017, and after six months living in Darwin's marina while we learned to sail, we headed off on our first big voyage, without any crossing experience, we made our way to Kupang, Indonesia. From there, we spent our days chasing waves, exploring islands, diving, and soaking up island life.
We sailed extensively through Indonesia, especially spending a lot of time in the Mentawai Islands West Sumatra surfing and spearfishing up and down the coast of Sumatra. Paradise is perfect for like-minded adventurers--she's spacious, with lots of room on board, full headroom throughout, and a dry cockpit that keeps you protected in wet weather. She's a very liveaboard boat, comfortable and practical for long-term cruising and living aboard.
In 2022 we moved back onto land to start our new journey of raising a young family, and although we've done some trips here and there, we've made the tough decision to pass Paradise on to someone else ready to start their own journey. She's been an incredible vessel for us, and we hope she'll do the same for her next owners. "
