Rigging Length of Line Chart
As the boat and associated gear ages, the running rigging can also show signs of wear. Keep an eye out for chafed spots or badly frayed ends. Older halyards can become stiff and have difficulty running through the blocks, making raising and lowering the sail more difficult. Weathered mainsheets can also make sail trim more burdensome. New running rigging and blocks with ball bearing sheaves will greatly improve your sail handling abilities.
If you need to replace any of the lines you can refer to the chart below for the proper lengths and diameters. Please keep in mind we maintain a full inventory of running rigging for all our boats. All lines are cut to the proper length and each end is whipped with waxed whipping twine. Call or email for pricing or to place an order.
We use 3-strand polyester (dacron) as standard equipment for all of our catboats. We also stock braided line.
