In my experience, a polyester / polyamide / polypro knotted or knitted net properly installed will give the boat owner a firm platform to stand or lounge on. Knitted nets, with their smoother finish are more comfortable than knotted nets, which are favored for heavier work such as found on charter boats, day charter boats and diving. Metal grommets can chafe or cut the rope used to secure the net to the boat, and since the grommets are usually punched at set increments, the net is not as flexible to install.
