From single-point moorings, to the dual point “Catalina” moorings, the need for free floating and individually moored boats and yachts is very big. There are more individually moored boats in the world than boats at marinas.
Traditionally, single-point moorings (SPM), also known as single buoy moorings (SBM) or swing moorings, have been done using a catenary chain solution, whith the inherent issues of corrosion and bottom dragging.
The corrosion of a chain-based mooring solution clearly affects the longevity and economic viability of this method. Using chains in corrosive environments means that each link must be inspected frequently, and in many cases much of the chain will have to be replaced regularly over the years. A cheap initial cost can soon be outweighed by the cost of frequent inspections and repairs or replacements.
Because of the material used in SEAFLEX, a longer life expectancy is possible for your single-point mooring. Compared to traditional steel components, the “marine grade” stainless steel in SEAFLEX along with its plastic parts and rubber elastic component has a much better resistance against the corrosion process. There are several very old installations in Sweden – the first market SEAFLEX was introduced in – going back as far as 1970. Some of these are still in use today, with the same SEAFLEX and attachments as the very first day!
Of course there are other sites which offer an even more corrosive environment for the steel components, but the stainless steel parts of the SEAFLEX will still outlive any normally used non-stainless steel components. In case of installation sites with extreme local corrosion problems, SEAFLEX can also be ordered with titanium parts to further increase the resistance against corrosion.
Bottom dragging is one of the main negative environmental impacts of these old methods of single-point mooring. A dragging chain can move around on the bottom along with the boat movements and create what is known as “dead spots“, often permanently killing the underwater flora in the area. Single-point mooring with chain close to coral reefs is also one of the main causes of damage to the reef ecosystem around the world.
The SEAFLEX mooring solution efficiently solves this problem. We believe that one of the main reasons for choosing SEAFLEX is the positive effect of the SEAFLEX units never touching or scouring the bottom sediments. Our system is 100% sure to not devastate the bottom living flora and fauna. The SEAFLEX unit is attached to a bottom anchor which is the only static point on the bottom; the mooring itself does not touch the bottom at all!
By using embedment anchors rather than gravity anchors the impacted area can be as small as 100mm². And this is only during the installation phase, after that no part of the mooring touches or affects the bottom.
