Supply Thread for Fishing Net Repairs

I spend most of my nights at sea and my income depends on a single pukat. Several panels have started to rip, so I need a roll of heavy-duty thread and, if possible, someone who can show me the proper stitching pattern so each repair holds against constant saltwater friction.

Here is what I’m after:
• High-tensile, salt-resistant thread compatible with nylon trawl mesh
• Enough length to patch multiple one-meter tears
• Simple, illustrated instructions (or a short video) on the best hand-sewn knot for sealing the edges

Please confirm the thread’s specifications, estimated delivery time to my dock, and whether you can include that quick how-to guide. I’m ready to order immediately and will leave fast feedback once the net is seaworthy again.
