I'm swapping out my wire lifelines for Samson's Amsteel on our Olson 30. I've read the IASF regs, and this is at least Cat 3 compliant for monohulls, and I think Cat 1 as well. Most of the boats in my class are using 3/16", but I'm wondering if 1/4" might be better handling... It also would probably last longer, especially if you shield the portions running through the stanchions. Has anyone got any experience with the same issue about line size?
