Synthetic rigging has come of age. Colligo Marine is now taking orders for made-to-order twelve-strand Dynex Dux (pre-stretched Dyneema SK-75) shrouds, backstays, and forestays (and other standing rigging), which are compatible with either lashing or turnbuckle-style tensioning systems. Colligo claims that the synthetic rigging is roughly the same cost as stainless-steel wire shrouds but is only one-sixth the weight; it also says its synthetic rigging is only one-third of the cost of either PBO or carbon-fiber standing-rigging systems.. Available for boats from 10 to 70 feet. Call for custom pricing. Colligo Marine, 480-703-3675, (www.colligomarine.com).
