Ph.D. Cruiser Rope

Double Braid


Ph.D. Cruiser Rope

Thanks to the innovative engineering team at Yale Cordage, the old-fashioned, bulky double-braided core-and-jacket combo has evolved into a silky-smooth high-performance line.

"Four years in development, Ph.D. delivers true game-changing performance."

  • Grips in your hands comfortably, making sheets easier to grab, hold, adjust, and control. No more wrestling with hard, wiry ropes.
  • Grips winch surfaces securely, so you can use fewer wraps to control loads more easily; release more smoothly and cleanly; and minimize slipping, catching, and stuttering.
  • Grips and holds highly loaded knots and hitches.
  • Glides through blocks faster and more smoothly for more effective trimming, tacking, and gybing. Ph.D. even glides around shrouds and other high-friction areas more easily than standard sheets. Enables much smoother spinnaker handling.
  • Glides when released without kinking or hockling. There's no bulky core-and-jacket combo to hold a show-stopping twist!
  • Ultra-lightweight sheet also compacts nicely for easy storage.

Ph.D. securely grips in your hands and on winch surfaces to give you safe and deliberate handling, yet it glides through blocks like a dream.

Bundles of continuous-filament polyester are encapsulated in sleeves of iGrip, Yale's proprietary fiber coating process, which dramatically improves grip on winches and in your hands.

Ph.D. Cruiser Rope Splicing Instructions

Ph.D. splices in under three minutes. This eye splice is more than twice as strong as a knot!

Eye Splice Instructions

Tools Needed:

  • Fid*
  • Knife
  • Pen
  • Tape

Use this chart to select the right fid length:

Rope Diameter Fid Length
Inches MM Inches
1/4 6 5 1/2
5/16 8 6 3/4
3/8 9 7 3/4
7/16 10 9 1/2
1/2 12 11

Measuring and Marking the Eye

Mark the rope at one full fid length from the tail end (1).

Form the eye to the desired size, laying the rope's body alongside the tail.

Mark the rope's body (2) adjacent to 1 and again (3) adjacent to the rope's tail.

Closing the Eye

Tape the rope's tail to the fid's angled end as smoothly as possible.

If using a closed thimble or hardware, place it in the eye.

Insert the fid into the rope's body at 2, running the fid down the core.

Push the fid's tip out through the side of the rope's body at 3.

Pull the fid and the rope's tail through the rope's body until 1 and 2 come together.

Mark the tail where it exits the rope's body (4).

Grasp the tail, and slide the rope's body up the tail toward the eye about 3 inches.

Cut the tail at 4 at a 45-degree angle.

Burying the Tail

Grasp the eye, and smooth the splice down the rope's body to draw the tail end back up into the rope's body.

Whipping or Stitching

This splice is more than twice as strong as a knot — even before whipping or stitching!

A brummel or whipping will help to prevent no-load separation.
