Boat and Knots
My Boats A navigation page with links to my various boat builds, sails and spars.My Ten Knots The 10 knots I use around my boats. I've finally figured out a good assortment of knots that seem to do the job.
My Carbon Fiber Mast
I built it and documented the build.

Trade Names of Rope Materials Manufacturers
I was trying to compare the qualities and characteristics of various rope material for use on boats, and was getting bogged down with the trade names. After a bit of searching, I think I sorted out the most common rope trade names. Trade names and Companies is a changing landscape!
I'm building a comparison table about the properties of the different rope making materials, and will post it when its done.
ARAMID, PPTA
A high strength, high modulus fiber.
Kevlar and Nomex: duPont trade name for aramid.
Twaron and Technora in the Netherlands are aramids produced by Teijin
NYLON OR POLYAMIDE, PA
Atlas: Bexco (Belgium), Drahtseilwerk Bremerhaven and Lankhorst Euronete trade name for a rope manufactured with two forms of nylon. Half the outer yarns on a strand are fine multifilament nylon fiber. The other outer yarns are large monofilament fibers (tradename Perlon).
Perlon: Bayer Chemical Co. (Germany) trade name for nylon.
Caprolan 2000 nylon with proprietary coating, offers dramatically improved wet strength and abrasion resistance
POLYESTER, PES, PET
Terylene: ICI (England) trade name for polyester.
Dacron: duPont trade name for polyester
Deltaflex: Bexco trade name for a high strength polyester and polypropylene mixed fiber rope.
HIGH MODULUS POLYETHYLENE, HMPE, POLYETHYLENE, PE
Spectra: Allied name for HMPE fiber.
Novabraid uses Spectra from Honeywell, I'm not sure how Honeywell is linked to Allied but they are both associated with "spectra"
Dyneema: DSM (Dutch State Mines)
Amsteel Blue Winch line is made from Dyneema with material from Samson's Amsteel blue rope.
Quantum-8 is another specialized UHMWPE rope by Samson. It has higher friction than the usual slippery UHMWPE. Used for wire replacement.
polyolefin: The chemical group which includes both polypropylene and polyethylene. This term might refer to either of these fibers.
MIXTURES
Supermix: Marlow trade name for a polyester-polypropylene mixed fiber rope.
Jetkore: Samson/American trade name for a 6 strand rope of nylon, polyester, and polypropylene.
Nystron: Samson trade name for a double braid rope having a nylon core and a polyester cover.
Karat: Scan Rop (Norway) trade name for a polypropylene-polyester copolymer fiber material, also used in ropes by several other manufacturers.
Power Braid: Samson trade name for a double braid rope having a polypropylene core and a nylon cover.
Ultraline: Samson/American trade name for a polypropylene-polyester copolymer material rope.
Poly-Plus: Wall Industries trade name for a polyester-polypropylene rope.
LIQUID CRYSTAL POLYMER, LCP
Vectran: Hoechst Celanese name for liquid crystal aromatic polyester fiber
POLYPROPYLENE, PP
polyolefin: The chemical group which includes both polypropylene and polyethylene. This term might refer to either of these fibers.
Nelson: Marlow trade name for polypropylene rope.
