John Blumenthal was born in Sydney and raised in the Bay of Islands, New Zealand.  

His love of the water has taken him around the world as a professional crewman and boat captain on marlin boats, particularly on the Great Barrier Reef, in Central America, and throughout the Caribbean.  

John settled in the U.S. in 1991 and worked as a Captain for boat owners until 2005, when he became a licensed boat broker. 

He has extensive, decades-long experience in boat sales, is honest and easy to work with, has great attention to detail and a tireless commitment to his clients.  

Apart from being a very successful broker in the US … John’s specialty is sourcing pre-owned boats for Australian and New Zealand clients, thoroughly inspecting them and reporting to those prospective buyers on the condition of the boat, closing the sale on their behalf and shipping the boats to Down Under. 

He has many clients in Australia and New Zealand (see the testimonials below), who have purchased boats from the US with him, without having to travel to there to inspect the boat and for whom he has made the shipping and import to Australia and New Zealand process easy. 

Many of these clients have referred John to friends, who have also purchased pre-owned US boats from him. 

The US preowned boat market is vast and there’s more choice of boats for sale than in Australia and New Zealand, so whatever type of boat you are interested in, contact John and get him to work on your behalf.
