The design of this mooring spring combines the concept of simplicity and the easiness of installation. Light, safe and resistant, it employs only the 10% of its potential to absorb the bumps that the boat could be subject of during sea storms, protecting the mooring from the wave motion and ensuring better comfort on board. A supreme high-quality boat shock absorber, resistant to UV radiations, non toxic and environmentally friendly. Ariel does not produce annoying squeaks. It is stain proof, does not scratch the hull and does not deteriorate in the marine environment, even if left for long periods in the water.
