Veteran-owned and Northeast Florida-based, Blackfin Marine Group provides professional vessel delivery, inspections, sea trials, transport coordination, and operational support for boat owners, brokers, marinas, and service facilities.
Serving Jacksonville and surrounding coastal regions, Blackfin Marine Group LLC was created for vessel owners who want experienced guidance from someone who understands the responsibilities of boat ownership. Founded by U.S. Army veteran and U.S. Coast Guard licensed captain Brandon Diaz, Blackfin Marine Group is built on real-world maritime experience and the principles of safety, reliability, and attention to detail. From helping owners manage their vessels to coordinating deliveries, conducting sea trials, and providing captain services, we deliver practical support backed by experience.
Every vessel has its own story, and every owner has different priorities. At Blackfin Marine Group, we take the time to understand both, treating every vessel with the same care, attention, and professionalism we would expect for our own while building relationships that last beyond a single service.
Backed by real-world maritime experience, Blackfin Marine Group brings knowledge and careful planning to every service.
We believe great service starts with communication, attention to detail, and a commitment to doing the job right.

Captain services are not only for owners who are new to boating. Many experienced owners use a captain for additional support, vessel familiarization, assisted passages, or situations where having another experienced professional onboard adds value. We work alongside owners to provide the level of support that best fits their goals, whether that means learning a new vessel, preparing for a trip, or simply having a trusted resource available when needed.
Yes. Purchasing a vessel is a major decision, and we help buyers gain a better understanding of the boat before moving forward. Through inspection support and sea trials, we provide experienced insight into a vessel’s condition, operation, and performance so you can make a more informed decision.
A sea trial is valuable whenever you need to understand how a vessel performs underway. We commonly assist with pre-purchase evaluations, post-service checks, and acceptance runs to help assess handling, systems, and overall operation once the vessel is on the water.
Behind every well-managed vessel is thoughtful planning, clear communication, and experienced support. Let Blackfin Marine Group help you navigate what comes next.
