Last summer a rock climber friend gave us some Dyneema, a type of rope that is touted as being as strong as steel. Since rock climbers put their lives on their lines, we figured the stuff must really be strong and reliable. We started using it on deck to secure the paddle board and various other tasks and were impressed at the little rope's power.
Our main sheet, a combo line of steel cable and rope, was pretty stretched out... so stretched out that when we raised the main sail, the cable ended up on the wench, making a taut sail nearly impossible. After only like two months of whining, Mack finally listened and agreed to upgrade the lines. Hello Dyneema.
He ordered 10mm lines, and the company even whipped in an eye splice as a bonus. Mack had spliced rope before and is really good at it, but getting the lines in a ready condition was pretty awesome. One less thing on the list!
Now for the fingers-crossed work of swapping the new line for the old. Mack engineered a bridge between the new line and the old cable using duct tape and small piece of smaller diameter Dyneema. The plan was to pull the new line into position on the tail of the other line. What could possibly go wrong when there's a block at the top and the rope goes into the mast for about a million feet.
NOTHING WENT WRONG. I still can't believe it. Mack held his breath as we pulled the bridge bit over the block at the top of the mast. It seemed like we might have a problem getting it thru that part, but with a little extra tug, it hopped over the speed bump and we were home free.
We even swapped out the shackle on the end because why not?
Two people dumb enough to think anything is possible and smart enough to bumble their way into discoveries.
