Default HM Grommet

I'm guessing an HM line grommet is a brummel then bury one end this way and the other end that way

Working Rope has the instructions for the HM Grommet. It's a bit trickier than the Brummel, but doable. Mine didn't turn out as nice looking as the Brummels on the lifelines, but it is functional.

Default 2 million $ Cat life lines......

I just spent an hour on a 2 million dollar Gun boat catamaran. All Carbon fiber...everywhere. You cannot even order a generator for this boat. They had Dyneema (spectra) lifelines with soft eyes and lashed. No steel, no fittings. Also same for the lazy jacks. The knotless spectra webbing on the bows is reported to be 10 yrs. old on some boats. Made right at Bainbridge Island from N.E.T.S. company. If you ever get a chance stop by for a visit. The machine that weaves knotless web will blow your mind!
I figure the Gunboat could use gold if it was the best choice. All big roundworld cats are using spectra webbing and none has been returned.
The life lines on a 48' cat Looked like 3/16" or 1/4" so. Te 1/4" is 4k breaking strength. Guess all lifelines should be sized for humans, and not for the boat huh?
Same as I changed to on my 34' Searunner Tri in Mexico. Very easy change over.
