I was looking to purchase a  boat on the east coast and then ship it back to our home port in Ventura, CA. I needed an experienced yacht broker, someone I could trust and preferably a licensed captain. In other words, someone who really understands vessel capabilities and operating systems and could spot potential problems, I was introduced to Grant Ninneman. Grant is not only a captain but one with trans-pacific experience. With his guidance and keen eye I found the boat we were looking for. Grant then went on to negotiate a lower price than I thought possible. Grant’s a great guy and brings a lot to the table.

Our Denison yacht broker, Grant Ninneman, was invaluable in helping us purchase our Nautitech 44 catamaran in Martinique. Purchasing a boat in a foreign country, dealing with documents in a foreign language, foreign currency, and unfamiliar laws can be extremely daunting. Grant held our hands through the whole process..His efforts made a huge difference in our anxiety levels while going through the occasionally very tough process. We highly recommend Denison Yachting and Grant Ninneman for any yacht purchase, especially if purchased outside the US.

Grant goes above and beyond for his clients..and he really cares. He’s also a captain and a prior- service manager who always has time for me if I’m confused about something or need something for my boat. He’s never not replied to a text or email. You should buy your boats from Grant!

Grant has an easy style to make you feel welcome and comfortable.  That helps when you are learning to pilot a yacht which can be intimidating.  It is also clear he possesses boat systems experience to help someone make a good choice in purchasing a vessel.

It is a distinct pleasure for me to write a recommendation letter for Grant Ninneman. I have had an opportunity to meet and work with Grant during the purchase of my yacht from Denison yachting. He was able to teach me and my wife the specific features of this yacht and how to maintain it. He also helped me to move it from Denison yards to my dock at Aventura.

It was immediately clear that Grant was very competent and skillful in seamanship. He had the full understanding of how the boat works and how to maintain it. He was also a very patient and knowledgeable teacher. We really enjoyed learning from him as he was so eager to share his love of seamanship and knowledge with passion.

There is no doubt that Mr. Bob Denison has very competent staff working in his team. Having a person who not only knows and loves certain skills but who can easily teach these skills.. is rather hard to find

Grant is a great teacher. He has a lot of patience and makes learning fun. I had no prior boating experience before I purchased the GT 40. Grant made me feel comfortable operating the boat in a matter of a few hours. He is encouraging, responsible and motivating: perfect skills for a remarkable instructor.

Grant Ninneman provided excellent training for me during the past month and I am completely satisfied with the instructions he provided. I fully recommend Grant for anyone who wants to learn boating basics and advanced training.
