Day Sailor Life Lines

[osteoderm]

Instead of a hitch or a turnbuckle, consider a simple lashing; adjustable, light, and in blue line would also match the boat...

[Essington]

oooh! I hadn't thought of the lashing route.

Would a 2mm or 3mm polyester double braid be sufficient for that, or should I use something like Spyderline with a dyneema core?

How about the eyes on the life lines? if I use the lashing, do I need to add a thimble to the splice?
