Ronstan’s ILCA® mainsheet blocks provide the perfect balance of strength, performance, and reliability Ronstan is known for. They feature a 2-stage bearing system which minimizes friction and gives sailors ultimate control while trimming. The cheeks and housings are lightweight yet strong and made from toughened glass fibre reinforced nylon. All stainless steel fixings and rivets are grade 316 stainless steel. The linked traveller block uses the same 2-stage bearing for the mainsheet sheave while the smaller traveller sheave has a simple AP bearing. Several concepts of the articulation point of the linked traveller block were tried and tested by ILCA® sailors to ensure the best design was achieved for optimum articulation.
