Boat Lift Cable is made up of 7 x 19 aircraft cable. Aircraft cable is specified by the number of strands in the rope times the number of wires in each strand. For example, “7×19” means the rope has seven (7) strands, with 19 wires in each strand. 7×19 is the most flexible aircraft cable construction.
If you have a boat lift, the cable is one of the most used components that require proper care and maintenance. If you look closely, the cable is made of multiple wire strands and wraps. When there is excessive corrosion or fraying, the cable becomes prone to damage.
BH-USA recommends 7 x 19 aircraft cables for boat lift applications. 7 x 19 means the rope has seven strands and there are nineteen wires in each strand. Always consider at least a 5:1 safety factor when figuring working loads. A test certificate for all cables sold by BH-USA is available upon request.
7 x 19 aircraft cable is not suitable for use in aircraft controls.
Aircraft Cable
Aircraft cable is specified by the number of strands in the rope times the number of wires in each strand. “7 x 19” means the rope has seven (7) strands, with 19 wires in each strand. 7×19 is the most flexible aircraft cable construction.
Swaging
Swaging is a method of securing wire rope or aircraft cable with a permanently applied fitting or sleeve. The swaged connection will exceed the rated breaking strength of the wire rope or cable when properly applied.

The drop is the individual piece of cable from the boat lift to the sling or cradle. Boat lifts have a minimum of 4 drops straight line and 8 drops compounded. The cable must be 7 x 19 aircraft-grade and less than 2 years old. These ratings drop after 2 years and all cables should be replaced after 2 years. What size boat lift cable do I need to lift my boat? Any boat heavier than 6,000 lbs. needs the boat lift cable to be compounded. We use the ASME (American Society for Mechanical Engineers) recommended safety factor and rating system, which is the same used in the overhead crane industry. Never use “Breaking Strength” for rating a cable.
