About YMP

Yacht Management Professionals (YMP) started when Grif saw, and experienced, a huge problem that occurs on a daily basis in the marine industry.

That problem is that boat owners and captains have a hard time referring people to do good efficient work for a fair price and trust that it gets done correctly. For a long time, owners and captains have had to settle and be frustrated with their results due to lack of communication, inconsistent follow through, and unprofessional work. It’s mostly a shot in the dark dealing with the next company unless they have built a reputable business. That is where YMP comes in. We practice what we preach!

Our seasoned crew of dedicated professionals are more than just skilled laborers. We are made of a passionate group of individuals devoted to  the marine industry who love what we do and it shows in our work.

We treat each boat as if it were our own! As a team, we aim to go above and beyond what we are hired to do and work hard to exceed expectation. As a whole, YMP possesses a continual strive to live out our company motto… “Enjoy the water. We got this.” This means your vessel is always ready to leave the dock. We encourage you to go enjoy your time on the water without any worries, Yacht Management Professionals will take care of the rest!



Yacht Management Professionals

 Grif Blackstone – President

Grif bought his first sailboat at 15 years old and learned to sail on Lake Erie. Realizing the lake wasn’t big enough at just 19, he sought out to do a transatlantic on a 192′ motorsailer as a 2nd mate. He spent three years extensively traveling the Mediterranean and the Caribbean Sea then continued his passion for boating and the water by moving his company Blackstone Agency, a marketing agency specializing in the marine and aviation industries, onboard a yacht in Marina Bay. Grif has lived, breathed, and literally worked on boats for most of his life.
