Sailboats classified as superyachts put tremendous strain on their running rigging. That’s why A+ Rigging of Mallorca, Spain chooses Vesconite, the advanced marine polymer, for components that routinely have massive working loads, yet need to run freely without lubrication such as halyard sheaves.
Ultra-low friction Vesconite has a compressive yield strength of 12,750 psi, yet is self-lubricating, making it ideal for rigging that cannot be inspected with any regularity. It has exceptional wear resistance and for areas where it’s exposed, excellent UV resistance. These features and the ability to machine to exacting tolerances of +/-0.001″ are why so many sailboat makers use the polymer, including an America’s Cup foiling catamaran.
“We tested Vesconite the first time 15 years ago as a bearing material for a spinnaker halyard sheave on a large yacht,” said Marko Bakker, A+ Rigging project manager. “We realized it was the only material that didn’t melt under high load and high speed.” A+ Rigging uses Vesconite exclusively on mast and deck sheaves, boom gooseneck fittings, hydraulic winches and furling gear. “It has proven itself to be the best material out there; it doesn’t disintegrate or need lubrication and is easy to machine.”
Founded in 1996, A+ Rigging Mallorca is the leading superyacht rigging service center in the Mediterranean. It’s experienced with all types of sailboats, from classic to high-performance yachts. The company has longstanding relationships with all major mast manufacturers and is highly skilled with rod, metal and synthetic wire, and carbon fiber rigging.
