Oceanographer's Brait

This plaited rope is the most predictable nylon rope you can buy. Yale 1 starts by utilizing nylon 6 which has a much higher energy absorp-tion capability than nylon 6-6. This can mean the difference between a mooring that stays on station or is lost. 2 The fiber is twisted to add firmness, 3 twisted again to add additional energy absorption, and 4 then ply twisted as we close the strand using a counter twisted veneering yarn creating a better balanced strand. All of this makes a rope that is firm enough to be used over a less than perfect deck. 5 Yale then plaits the eight strands loosely enough to accommodate a shrink process which further enhances the product. 6 Steam stabilizes the rope over an eight hour period so the shrinkage and strength reduction you have had to deal with in the past is eliminated. Although this firms the rope even more, there is no subsequent shrinkage so the rope splices just as easily after use as it did the day you deployed it. 7 If you elect to have your rope stretched over our automated equipment you can eliminate the guesswork of what the permanent non-recoverable elongation component of your rope will be after you deploy your mooring. The curves below show the difference this step can offer. This process will also increase your rope's length 4-8% permanently.

* Knots
and abrupt bends significantly reduce the strength of all ropes and lowers the maximum working load.
** 33% of break strength. Your application may dictate a different maximum working load.
