IN-WATER DRY DOCKING SYSTEMS
An in-water dry docking system works by separating the hull of the boat from the water without lifting the boat out of the water. These devices deflate in the rear to allow the boat to drive in and out of the liner. Once the boat is inside, the back of the device inflates, and the water between the boat hull and the liner is removed to leave the boat dry. Additional benefits are provided by the inflated chambers that surround the boat, protecting the hull from collision with the dock. If interested in seeing an in-water dry dock in person, there are two being tested by private boat owners at Anchorage 47 and are visible from the promenade.
Boat lifts are devices used to raise a boat out of the water while it is docked in a slip. They help protect the boat from marine growth, corrosion, and other potential damage, such as electrolysis. Boat lifts greatly reduce or even eliminate hull maintenance requirements, including in-water hull cleaning and periodic painting, which can save the boat owner money, increase the resale value and extend the lifespan of the boat.
Boat lifts can be used as an alternative to antifouling paints to prevent algae, barnacles, and other encrusting organisms from developing on the hull by keeping the boat out of the water while in the slip. The use of boat lifts typically reduces loading of copper and other contaminants to the marine environment since the boat lifts do not require chemical protection from fouling growth. There are currently several brands of boat lifts in use in the Marina del Rey Harbor.
CONVERSION TO NON-BIOCIDE HULL PAINTS
Non-biocide hull paints do not release metals or other toxins into the water. These hull paints work one of two ways:
- Hard non-biocides can provide a protective barrier, which would be cleaned more frequently.
- Soft non-biocides can provide slick surface making it more difficult for marine organisms to attach to in the first place, but need to be cleaned more carefully to prevent paint damage.
The County is implementing a pilot hull paint conversion program to help promote the effectiveness and use of non-biocide hull paints. As part of the pilot program, County-owned boats were painted with non-biocide hull paints to study the costs, maintenance requirements, longevity and overall effectiveness of non-biocide hull paints. More more information, including pilot study results, visit the Alternative Hull Paints & Coatings webpage.
All Marina del Rey Harbor boat owners interested in participating in future copper reduction programs should fill out the Interest Form below, to be added to the copper reduction program interest list. We will then contact you as opportunities to participate arise.
If interested in learning more about the County’s copper reduction programs, you can email the program contact by filling out the fields below.
You may also join our new boater outreach email list, which the Department of Beaches and Harbors will utilize for program updates, new programs, requests for feedback, and other outreach in an effort to have more direct communication with the Marina del Rey boating community.
We look forward to speaking with you!
