When most people look at a racing sailboat, they see speed, grace and teamwork. At Yale, we see a living laboratory, where rope is exposed to dynamics rarely — if ever — experienced in other applications. That's why we test our sailboat racing ropes both in our labs and at sea, where reliable performance can define the difference between victory — and everything else.
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.

Crystalyne is a double-braided rope constructed with an inner load-bearing core of Vectran Liquid Crystal Polymer (LCP) and has a tough polyester outer sleeve. LCP is more tolerant of bending than other high-modulus fibers and is not as affected by overloading.
Maxibraid is a 12-strand single-braid rope constructed from Honeywell Spectra® fiber. Spectra® has the highest strength-to-weight ratio of any synthetic or natural fiber, and it floats. The integral Maxijacket High Performance coating firms the construction, increases wear life and helps keep contaminants out of the rope.
Maxibraid Plus is a double-braided rope constructed of an inner load-bearing core of Honeywell Spectra®. The polyester outer sleeve is slightly thicker than Ultrex Plus, which would provide more abrasion resistance in high-wear applications.
Ph.D. is different than any rope you've used or seen before. It feels like fuzzy polyester but performs like 100% Spectra®. 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.
PoBOn is a double-braided rope consisting of a polyester sleeve covering an inner load-bearing core of 100% Zylon PBO polyester, a rigid isotropic crystal polymer. PoBOn has outstanding tensile strength, high modulus, flame resistance, and thermal stability.
Ultrex is a 12-strand single braid of Honeywell Spectra® fiber enhanced with Yale’s Maxijacket High Performance coating, which supplies superior abrasion resistance. Ultrex's braid angles and twist level are designed to optimize break strength and keep stretch low.
Ultrex Plus is a double braid of Honeywell Spectra®, treated with Maxijacket coating for enhanced toughness. Sleeved with high-tenacity polyester, Ultrex Plus is spliceable, using conventional high-modulus splice techniques or the new Yale tuck splice, which shortens the bury portion and minimizes the length of the larger diameter associated with a bury-type splice.
Vectrus is a single-braid rope of 100% Vectran™ LCP (Liquid Crystal Polymer) and is always treated with Yale’s Maxijacket coating to increase abrasion resistance and enhance the fibers' UV resistance. LCP is more tolerant of tighter bending radii in terminations than other high-modulus fibers.
