For an owner thinking of building a marina or rebuilding an existing marina, the new Attenuator Planning Tool is a sensible way to kick off or accelerate a project.
By Robert Wilkes
The new Attenuator Planning Tool was developed by Bellingham Marine and SmithGroupJJR. It saves time and money; a lot of time and money. A pre-construction evaluation process would normally take weeks and run up a tidy number of engineering hours. Using the Attenuator Planning Tool takes about four or five minutes and is free. The tool answers key questions about wave attenuation in normal and extreme weather conditions. The resulting data is directly related to the cost and feasibility of the project.
The system was a cooperative project by Bellingham Marine and SmithGroupJJR. Jack Cox has 40 years of experience in marina and harbor engineering and wrote a book on floating wave attenuators. He’s also one of the authors of “Planning and Design Guidelines for Small Craft Harbors,” the current standard for marina layout and design.
Margaret Boshek is also an accomplished and comprehensively trained coastal engineer with a talent for building computer-based analysis tools. She encoded the system and created the user-friendly interface for both the Attenuator Planning Tool and the Wind/Wave Analysis Program. The system allows the user to change the variables and test multiple design choices quickly. Once the required data is loaded in, the user can vary a number of factors and see the effects a few seconds later.
Embattled by rising maintenance costs, Alamitos Bay Marina initiated a program in 2005 to rebuild all 1,962 slips in seven different basins.
By Robert Wilkes
The timber docks dated from the 1960’s and were 20 years past their projected life span. No one at the City of Long Beach, California, imagined it would take the next 13 years to complete the project.
The marina is south of Los Angeles and enjoys a uniquely loyal customer base. There are tenants who have been there for decades whose children and grandchildren are also renting slips. Over time, neighboring tenants have formed tight communities.
The City’s marinas are operated by the Marine Bureau, part of the Department of Parks, Recreation and Marine. Three City-owned marinas total 3,337 slips: Alamitos Bay Marina, Long Beach Shoreline Marina and Rainbow Marina. Alamitos Bay is the largest marina in the U.S. The rebuild project started in 2005 and has been undertaken in phases. The final phase will be completed in mid-2018.
Reasons for the length of the project are size, environmental compliance and the timing of funding. Elvira Hallinan is the Marine Bureau Manager. “Most operators have a marina the size of one of our basins,” said Hallinan. “We had seven basins to rebuild. It wasn’t a project, it was a journey.” Delays caused by the Environmental Impact Review (EIR) were unanticipated. Contractors were ready to begin when the requirement for a full EIR delayed the start of construction. Continue Reading…
For versatility, it’s hard to beat concrete floating platforms.
By Robert Wilkes
Floating platforms provide foundations for stores, offices, yacht clubs, rowing club facilities, boat rental concessions, charter and cruise companies, customs offices, harbormaster offices, restaurants, bars, restrooms and houses. They serve as ferry and water taxi landings and create a platform for event space, rowing docks, swimming pools, helicopter landing pads, even floating golf greens, such as the 14th green at The Coeur d’Alene Resort in Idaho.
The performance and endurance of concrete floating platforms is outstanding. They can be built with almost any freeboard and can be square, round, curved, sloped, stepped, notched and decked in any way the owner specifies. They support building of every style and building material. Floating platforms are limited only by the imagination.
Many public and some private marinas invite the public to experience the waterfront. In a social-equality world, marina projects win public support by incorporating community activities and park areas and opening promenades and beaches to all. Alamitos Bay in Los Angeles, California, has done away with fences and security gates altogether.
Floating platforms help make marinas more accessible. Marina and park complexes, such as Marina Park at Newport Beach or The Yards in Washington, D.C., provide romantic event venues, schools and classrooms, and places for family gatherings. Continue Reading…
The 2017 has been an exciting year for new materials in dock construction.
By Robert Wilkes
Two new Fiberglass Reinforced Polymer (FRP) applications have emerged from years of R&D development and are on the market. In the fast-growing market of wood and aluminum docks, a handsome and rugged hybrid dock that combines the best of both materials was introduced.
The durable, stable, reliable concrete floating dock is the world standard heavy-duty dock and that is not changing. Two design challenges remain: corrosion in metal parts and the eternal quest for the zero maintenance dock.
Stainless steel thru-rods, washers and nuts make up a significant portion of the metal in a concrete dock system. Thru-rods attach the walers to the side of the dock and, because the walers are layered and lapped, they make the connection between modules. The timbers flex with the movement of the dock and physical “hinges” are not needed.
During the first six months following installation, it is common for the wood waler to shrink. This can cause the tension between the nuts at the end of the thru-rods and the waler to become loose. It’s a simple task to restore the tension and can be done with a set of hand tools. Manufacturers recommend annual inspection of the steel rods to ensure the nuts are tight. Continue Reading…
Learn how to attract Millennials to your marina. Think functional luxury. There are some simple features you can incorporate into the design of your marina that will appeal to the Millennial generation.
By Roxie Comstock
High-spending Baby Boomers, floating concrete docks and affordable fiberglass boats built the boating and marina industries we know today. That was then. Today we are facing a serious challenge: as Boomers pass the keys and floating key fobs to the next generation of boaters, who are they passing them to? What do these new boaters want in a marina?
Millennials are the up and coming generation and will make up the bulk of our boating population. They are attracted to a different set of facilities and services than those that once satisfied the Boomers.
The definitions of Millennial vary, but they are generally described as those born from the early 1980s to the early 2000s. At about 80 million souls, they are the largest demographic cohort in U.S. history. Understand their approach to life and you have a window into the future.
