Grant Ninneman

I have 50-plus years in the marine industry. During this time, I owned and operated a 350-boat marina that offered full service and retail sales. I found Grant Ninneman from Denison Yachting to be, without question, the most responsive, knowledgeable yacht broker I have ever met. I still can't believe that any time I call, he either answers the phone or texts an immediate response.

I flew to Fort Lauderdale from Annapolis, Maryland multiple times, in which Grant set up between four and six boats each time for my review. He also performed numerous live video reviews showing the good, bad, and ugly on several other prospective boats.

I could not have been more fortunate to connect with Grant. I immediately found him to be knowledgeable, responsive, and an excellent sounding board. He was able to answer/explain all of my questions/concerns through his actual boating experience (he captained boats all around the world) with real knowledge that I knew from my experience was accurate.

He offered an excellent balance of providing his point of view when asked without pushing any agenda. He invested a significant amount of his time and was very responsive throughout the whole process.

I quickly realized Grant’s own extensive yachting background as a captain and in yacht design, features, and capabilities. He was very patient in explaining each boat’s design and mechanical features as well as answering all my questions. We spent several days visiting yachts before finding a 2007 70' Princess Yacht.

Grant is extremely knowledgeable and very capable during the purchase process, including negotiating offers, arranging for a survey and haul out, obtaining insurance, and recommending service personnel for completion of work on the boat after closing. Even now, after the purchase, Grant continues to stay in touch.

I highly recommend him to anyone purchasing a yacht.

I met my yacht broker, Grant Ninneman, from Denison Yacht Sales over the phone when I relocated from Connecticut to Florida in search of a full-time liveaboard yacht. I could not have been more fortunate to connect with Grant. I immediately found him to be knowledgeable, responsive, and an excellent sounding board, which was critical to me being a first-time yacht buyer.

Before our first yacht visit, Grant and I exchanged ideas on my yacht preferred features and an initial list of boats I found for sale. Grant quickly reviewed the list, added his thoughts, and developed a multi-day visit plan.  As we toured each boat, Grant was very helpful pointing out the positives and negatives of each boat. He had an excellent balance of providing his point of view when asked without pushing a personal agenda. He invested a significant amount of his time and was very responsive throughout the whole process.

I quickly realized Grant’s own extensive yachting background, and knowledge of local marinas and yacht manufacturers enabled him to not only provide sales support but also expert knowledge on yacht design, features, and capabilities. He was very patient explaining each boat’s design and mechanical features as well as answering all my questions. We spent several days visiting many yachts before finding a 63-foot Hampton which was perfect for my needs.

Grant was extremely thorough during the purchase process including the initial offer, arranging for a survey and haul out location. We reviewed the survey results and Grant helped me organize an initial offer which quickly resulted in an agreement with the seller. Grant continued to help me through every step, including recommending an insurance broker, introducing me to the Denison team that would complete the remaining steps leading to my ownership and introducing me to a training captain. Being new to Florida, Grant even arranged for me to have lunch with him and his family to help me feel comfortable transitioning from home ownership to full-time liveaboard boat owner.

Even though the boat was located in Jupiter and Grant was in Dania Beach, he traveled several times to Jupiter to assist me. He helped arrange temporary dockage prior to and after haul out in Fort Lauderdale and made countless contractor recommendations for completion of work on the boat while out of the water. I could not have completed all necessary work without Grant’s help. For the months following the purchase, Grant continued to regularly reach out to me offering any assistance I may need. He continues to show a genuine desire to assist me even 4-months after purchase.

Grant could not have been more helpful, from the initial yacht search to the purchase process, and then post-sales support. I feel very fortunate to have Grant as my yacht broker. I strongly recommend Grant to anyone wishing to purchase a yacht.

Betty and I were so appreciative of Grant's efforts as our yacht broker on the sale of our trawler yacht. Our previous yacht broker did very little to aggressively “show the boat”. He advertised but was not an enthusiastic salesperson. Let’s say he “called it in.”

Grant, on the other hand, hit the ground running. He was a great advocate for the attributes of the Grand Banks. He was also quick to use resources to publish a very good video which we believed contributed greatly to the relatively quick sale once he took command.

I was very pleased with his focused efforts. Thanks again.

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!

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.
