Tow Line Diagram Notes

  • Overall Tow Line Lengths are recommendations only subject to alternations, review, and approval by the Captain
  • Overall Tow Line Lengths are effected by towing speed, weather conditions, and the resultant location of the towing boat's "wake sweet spot" of least turbulence
  • Pull-In or Pay-Out Tow Line Rope and or Adjust Towing Speed as needed to optimize the towed boats location within the wake sweet spot
  • The amount of force on the tow line is proportional to the towing speed squared (double the towing speed quadruples the force on the tow line)
  • The Tow Lines for the Runabout and Houseboat are Single Leg Tow Lines

These figures are for brand new rope. Age, wear, sunlight exposure, splices, and fraying will further reduce these figures over time
All hardware sizing is approximate where thimble size and rope thickness may require a larger shackle to fit properly
Heavy Duty Towing Thimbles are available to include NEWCO, Blue Line, NAVSEA, GN Rope Fittings, Rope Connectors, etc.
We also supply towing plates, wire rope assemblies, stud link chain, and additional hardware as required
Additional fiber and rope construction styles are available
When the bridle legs are 2x the length of the beam, the inside angle formed by the legs is very acute and the bridle leg strengths are additive
The inside bridle leg angle shall be 60deg or less where 30deg is very acute, but not to exceed 90deg
Most conservative is to approximately match the single leg strengths (DBN - Dyneema) and design the inside bridle leg angle to be acute

Tow Bridle

Above an example of a Fully Specified Ocean Tow Bridle: 58 ft Sovran Yacht by Tiara towing a 24 ft Center Console by Everglades. The bridle’s working load was chosen to be 4,500lbs, which is the estimated fully loaded weight of the center console. Notice that the center console stays in the middle of the wake even as the Tiara is making a port side turn.
All of our towing bridles and lines are customer specified, made-to-order, and manufactured in the USA!

Above an example of a Fully Specified Ocean Tow Bridle, St. Croix USVI: 65 ft Hatteras Yacht towing a 32 ft Century. For this tow bridle the W.L. was chosen to be 10,000lbs minimum, which is the estimated fully loaded weight of the Century.

Tow Lines & Recovery Ropes y-shape tow bridle

Above an example of a typical Y-Shaped Tow Bridle Assembly: To the left are the two black double braid nylon stern legs that connect to the stern of the towing boat’s cleats. The relatively long 12-strand dyneema tow leg is joined to the 2 stern legs using small soft covered eye splices, while the other end of the tow leg is provided with a hard eye splice using a heavy duty stainless steel wire rope thimble spliced to a stainless steel quick release snap shackle. At the top is the optional snubber line. The snubber line provides for ease of connection to the tow leg and allows the towed boat to be put underway with the snubber line still attached. Both ends of the snubber line are provided with heavy duty stainless steel wire rope thimbles. One thimble will receive the tow leg’s snap shackle while the other end of the snubber is provided with a stainless steel safety bolted shackle, which connects to the towed boat's bow eye tow plate. Note the additional sewing / whipping / lashing used to seat the rope within the wire rope thimble. As with all of our lines, our Tow Bridle Designs are fully customizable and made-to-order per the customer’s specifications.
