Dyneema net edging

Comment by kim whitmyre on May 30, 2012 at 9:34am

The net is folded over itself, and has two rows of continuous half-hitches that secure the boltrope; the boltrope itself should be half-hitched to the net itself at some point as this will make the net more stable.

The half-hitching was done with Samson's "Lash-It," also a dyneema product: 400lb load rating.

Looks like a good alternative to trampolines.  What is the cost of the dyneema netting and do you have any idea of its lifespan in full U.V. exposure?

Nice work Kim,I have bought some knotless netting too,mine is black but not dyneema. I like the fact that there are no dodgy eyelets to rely on but that you are knotting directly to the net hisself.

I got the "Ultra-Cross Silver Knotless Netting," that's a mouthful, from here:

Net Systems

They are on Bainbridge Island in Puget Sound, and sell mostly to the trawler companies.  They recognize the multihull market though. The net is sold by the pound, and I measured from the center line of the hulls, beam to beam. That amount of net was $300. I bought two rolls of Lash-It, but basically only used one for the half-hitching: great stuff to have on hand though. A length of 3/8" dyneema finished off the materials. Roughly $425 for materials.

Most dyneema is treated with a uv-blocker to extend its lifespan, but as with most things, if the net is covered when not being used, it will live longer. Here is a pdf file on trawler netting that has some info on wear and uv resistance of common  netting materials Fishing Nets

I reversed the flat-webbing tramp on Vaea's bows this season for this reason. The webbing tramp, 7-8 years ago,  from Sunrise Yacht Products in Florida, cost the previous owner a bit over $600

Once again, I'll probably be following your lead, Kim.  That's certainly not cheap, but I know it's strong and I like the open netting better than any tramp material.  It's also great that grommets are not needed, as they always seem to tear out on these tramps.  I've changed my mind on the slat deck up front and gone to a central catwalk instead.  I'll have netting on both sides of that, and in the stern on both sides of the ladder support rails.

Hey Scott,I was going to go with a central slatted catwalk myself,actually I had built one but the idea that it could be a wave catcher up front got me me to thinking maybe I could do without it.

Paul, mine is small and definitely lighter weight than the deck I started with (sold that one already to another T26 owner).  With 1-inch gaps between the planks I don't think it will hold much water, especially with nets on either side instead of tramps.  I think it will be handy for handing the anchor, cleaning fish, etc.  By the way, what kind of knotless netting is that you went with?  I might be able to live with something a bit less pricy than that dyneema!

Scott,the netting is Diamond mesh 250 ply knotless netting from a mob at www.haverford.com.au It sure is strong.

I may attach a catwalk over the top of the whole net once I figured out how to sail her...

Thanks Paul, I'll check that link out.  I'll post pics of my new catwalk soon.  Working on the cockpit seats right now.
