Luxury Yacht Marinas

Turrell, Hall & Associates specializes in the planning, engineering and construction management of marinas for the largest of private, luxury yachts in the world, sometimes known as megayachts. Slips 200′ + have become common and our firm has a dozen such projects in different stages of design, permitting and construction. We pride ourselves with “in house” knowledge of not only the waterfront structures necessary to safely moor these vessels but also the needed infrastructure, such as the massive amount of specialized electrical power and the other utilities needed. Large Yachts have other needs such as concierge services, access for provisioning, specialized fueling and crew facilities. We specialize in proper planning for all of the yacht’s requirements to keep them happy and coming back to your port. In association with Dream Harbors, our firm also offers operational expertise, facility management, and marina staff training in specialized areas such as fuel spill and emergency response procedures.

Terrestrial Biology

Land-dwelling species are often extensive and diverse, thus understanding how and where different species live requires thorough investigation and technical expertise. Our ecologists and biologists are qualified to execute all kinds of terrestrial investigations, including mandated procedures and guidelines required by federal, state, and county agencies. Our knowledge of the underlying dynamics of terrestrial ecosystems is used to manage them in an ecologically appropriate manner.

Marine Biology

Tidal wetlands, mangroves, submerged aquatic vegetation such as seagrasses and other submerged resources including corals, oysters, sponges are all critical components of the marine ecosystem. Our services provide an investigative approach that systematically surveys the project area in order to identify any resources present at the site, the percent of coverage, and limits by use of GPS. Our findings are presented in report form and complemented by underwater video and still photos to aid in dock design and processing of the necessary state, federal, and local government permits.
