Rope inc. recommends using nylon rope for dock lines and mooring lines; the stretch characteristics of nylon absorb shock and will resist damaging cleats on your boat and on your dock. Nylon is available in 3-strand or twisted line, 8-strand, 12-strand or Mega Braid and in a double braid or yacht braid.

See the table below for sizing dock lines and mooring lines for your application. Contact Us for more information regarding your specific application or to quote pricing for your new dock and mooring lines. We have the best prices and availability by far.

If your boat is heavier than average, or has greater windage, or is docked where it is subjected to surge, you should choose the next larger size dock line.

 
 

When making a choice of line for your boat, keep in mind that 12-strand (Mega braid or Brait) line is not as strong as double braid line and colored line is not as strong as white line. Different braids have different attributes and tensile strengths can vary by as much as 15%. Make your choice accordingly.
