I used it first to make a dinghy cover, which lets water through (and then out the stern drain hole) while protecting the inflated sides from UV damage. I'm getting ready to make a sunshade for the wheelhouse "patio" roof with it, because it has a wonderful property of not beating itself to death in a mild breeze when we are at anchor. Shaded happy hour up top.
I used the exact same product. It doesn’t block light like the solid sunbrella, but basically provide a nice shade that let some breeze go through. While my bimini is made from a silver sunbrella (that I also like a lot), this adds extra shade while docking or motoring. It is very light, strong and inexpensive. The same material can be used to make hatch and port covers

One technique that I like, rather than using grommets is to use lacing tape.

https://www.sailrite.com/Notions/Trims/Lacing-Tapes

It's stronger than grommets, very quick to apply and you just sew it to the hem of an item. Then use thin line to lace the edges to an eye, rail, or lifeline.

I used it to lace the bottom of a Phifertex holder for fenders to the toe rail of our boat.

Re: External DIY UV Shading material? Clever solutions? Experiences?

If cost is really important, you may be able to get some used, blown-out sails from a fellow boater. No good for sailing, but you could make them into sun shades fairly easily.

Some people hoist old sails in their back yards to get decent shade. (I think this idea came from Australia.) So much so that there is the Coolaroo product mentioned by a previous post, made into "sails" sold for this use:

All the work to retrofit an old sail to fit your need would be toast in one summer in the sea of cortez. Be cheaper to buy a roll of nursery shade cloth 95%. It will last for years. We used this for awnings and side curtains in the cockpit and got 7 years out of them.

Hey everyone, thanks again, we were talking about the actual shading and UV protection material for our hatches here.

Got the material and Tenara thread here now.

Well use it with the Sailrite fastener system:

That's actually what we bought but in a bit better quality which is used on balconies.

Cost about 20€ in total. The Tenara thread was more expensive :-)

Dont use the material that is plastic. It will make so much noise.
I used a cotton painters cloth but sun bleaches this cotton material.
Best yet would be to go to your fabric store and get 100% nylon fabric....print, solid whatever...sun proof and quiet
Cheap colorful and lasting.

Re: External DIY UV Shading material? Clever solutions? Experiences?

You night want to look at the SNAD fasteners, also sold by Sailrite.

With this system it apears you put the metal domed clip onto the fabric cover, and the domed ratainer onto the boat.

They are very low profile, an dno sharp edges ro whatever, and are recommended for fixing things like cushion covers underneath, so if you remove the cushions the SNAD that is left is 'foot friendly'.

Probably not cheap, but if 'foot friendly' is one of the main criteria...

Re: External DIY UV Shading material? Clever solutions? Experiences?

Thank you Buzzman.

Looks like Sailrite really has a ton of good stuff.

When installing onto horizontal surfaces these SNAD fasteners have surely advantages. Much more foot friendly than Loxx fasteners.

Still, I am not a big fan of plastic fasteners on a boat, because eventually they all fail due to UV.

As our fasteners in this application will go more onto non horizontal surfaces I think we'll use the Snaprite instead.
They are reasonably flat, seem to have good holding and are much more reasonably priced than the Loxx fasteners.

Loxx has perhaps better holding power, but they are not foot friendly at all and really expensive.
