Ph.D. is different than any rope you've used or seen before. It feels like fuzzy polyester but performs like 100% Ultra High Molecular Weight Polyethylene (UHMWPE). 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, with virtually no stretch.
"Ph.D. is light and grippy, perfect for the mainsheet on my foiling Moth, where every ounce counts. Yet it's strong and secure enough for the mainsheet on my 44' performance racer/cruiser."
—Jonathan McKee, two-time Olympic Medalist, seven-time World Champion
Ph.D.’s exceedingly strong UHMWPE fiber manages high loads, while Yale iGrip-treated outer polyester fibers make it easy and comfortable to handle and grip.
The key to this 12-strand single-braid’s superior combination of performance, handling, and strength is in its unique base-strand construction: Super-strong UHMWPE fibers are pre-stretched, bundled, and then encapsulated in sleeves of Yale iGrip, Yale’s proprietary fiber coating process, which dramatically improves grip on winches and in your hands.
"Four years in development, Ph.D. delivers true game-changing performance."
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.

Ph.D. splices in under three minutes. This eye splice is more than twice as strong as a knot!
Use this chart to select the right fid length:
|Rope Diameter||Fid Length|
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.
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.
Grasp the eye, and smooth the splice down the rope's body to draw the tail end back up into the rope's body.
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.
