Has anyone installed the glue-on type of D-ring cargo hold downs in a stitch-and-glue boat?

I've been looking to put some hard attach points inside the boat, but haven't made up my mind as to what yet.

Stitch and glue......is that a canvas like material covering the boat? I would think it could be done with a d ring that has an extra large rubber base as to spread the tension out moe on the boat's material, most caution excersized on the type of adhesive....just a guess

You can do really strong, really cheap hold-downs by taking a bare
D-ring, running some webbing through it, fraying the ends of the
webbing really well, then glassing the frayed parts down. Rough up your
hull a bit first. for good grab.

Do you have to use glass over the webbing? Can you just resin the nylon onto
the hull?

The resin will probably hold just fine. If you're using epoxy, it will definitely hold.
Just don't use polypropylene webbing - nylon or polyester are better.

I hadn't answered previously, since I've never used PVC fittings like this. I've made
my own D ring attachments - I took a plastic D ring (no rust) and stitched some
webbing to a patch of Cordura (fuzzy side to the hull). I used 3M 5200 to glue
them to an ABS bulkhead and it held just fine. I'd expect that 5200 would
hold it to any S&G surface, but I'm not sure about it's strength in bonding with
PVC.

I see no advantage to using glass cloth in addition to epoxy resin in this
application. I had originally thought to epoxy the webbing direct to hull,
but hadn't thought to fray the ends of the webbing first to allow better
epoxy saturation and maybe avoid an edge to catch on something. I give it a
try and post the results.

Well, so far I have tried fraying the webbing and dipping the frayed ends in mixed epoxy until saturated, then arrange the soaked ends in a fan shape on a piece of scrap 4 mm ply and weight down. Next day uncovered the mess to see a nice wedge shape from the webbing to a feathered edge at the ply. Cleaned up the epoxy a little with a Dremel 1/2 inch sanding drum and it didn't look half bad. Wouldn't come loose from the hull unless the ply separated. With the right color nylon webbing you could hide it well even in a *bright* boat and be left with just a small amount of webbing and the D ring showing.

The second idea involved 2 inch square ply pieces with 1 inch slot in the middle and recessed channel on the back side. Pass the webbing through the D ring and both ends thru the slot. Lay into channel, trim to fit then epoxy to hull.
I liked the *look* of the finished product and don't believe there should be any concern about strength, but the curve of the hull could be a challenge depending on placement.

I did take pix and will put up if any are interested.
