I don't know...but, wax rings seem to work pretty well sealing toilets. I carry a couple because it's the type of wax that when it's warm it can be worked into cracks in metal thru-hulls or welds that have given way and then it can be backed up with tape or other materials. The wax helps reduce the size of the opening...it's not for gluing things together.

As for Icarus...his problem was that he failed to heed his father's advice and flew too close to the sun, the wax melted, and, well, as they say the rest is history. BTW, Icarus' father built the wings...two sets in fact and then the father flew to safety on his wings by staying away from the sun. I don't think the critique of Icarus is one for illustration of faulty engineering, but rather the hubris of a dumb dude that didn't listen to the good advice of his father.

Looks like you did not watch the video posted. They did that in the video and showed how it worked. Nit something I would count on. Also, as they said in the video, how do you then patch the hole so you can get home with that stuff sticking out of the hole, inside AND outside.

When I talked about using the blue tarp, it was ONLY as step one to quickly stop the inflow of the water. The the Splash Guard under water epoxy, to patch the hull from the inside.

Once patched, the outside tarp, of any type, comes back aboard.

I was thinking of using it as a gasket material. Like with a long non round hole similar to the Yacht Monthly's video I would smash a bunch of that wax into the hole, then make a nice glob on a piece of wood and brace it from the inside and let the wax form a gasket to the hull.

The problems with the plastic on the outside of the boat...Unless it is large enough to come up over the bow and still cover the hole you are dead in the water. Once you move the plastic is going to get water behind it and it will release/compress/release/compress against the hole and end up sinking you. Also I wouldn't rely on a standard blue tarp from Lowes/HD because those are the cheapest things ever. The water pressure will make them fail. If you are going to rely on this then you need to use a thick plastic material like PVC coated fabric or similar. I used to make above ground holding tanks out of that material for the koi pond hobby and it is very strong.

Water activated glass mat is another option for emergency hull repairs. See (click-on) Syntho-Glass

The lesson from the Icarus story is not about human failing.
It is a lesson about the limitations of wax as an adhesive.
If you have an engineering problem solve it.

Re: Emergency Hole Patching Material

wet dry 700 kevlar reinforced epoxy putty has saved a lot of sinking boats and floating homes (as well as leaking swimming pools). Carried by a lot of offshore sailors. use with our without fiberglass cloth or as a glue to seal and attach patches. Of course these coatings pretty much have to be applied on the outside using the water pressure to hold and push them into place.
