I wanted to pass along a great source we used for inexpensive lifeline netting on our tartan 37, it's from a sporting goods company that supplies goal netting. We have had it on the boat for 3 years and it is holding up great! A single net for all the lifelines including the transom was less than $100 3 years ago!
