From SY de Verleiding, Rocna 25 on a Contest 37

While sailing throughout the Caribbean area, UK, Spain and Portugal, we have anchored in various terrains and never experienced any problems. As Rocna states, it is “Rock Solid”; in sand, soft substrate, coral sand, in grass and kelp. Even in a rocky bottom with 40cm sand substrate. In clay, it was difficult to hoist the anchor but we experienced 45 knots wind, in 5 meters with 35m chain 8mm out with no problem.
