Any problems with the glue not setting up properly due to a cold workspace would have shown up by now.

If your glue is holding now, then it msut have set up despite the temperature not being optimum. It should still be holding come the spring thaw.

Of course, if it gets colder and you put on some strips and they jump back at you when you move the clamps, well, then you know why: It finally got too cold.

When you epoxy the boat, either by putting on a seal coat, or when you apply the glass cloth and resin, you will get some epoxy soaking into those areas between the strips that your glue did not fill. This will hold things nicely even if your original glue should fail at some future time. And of course the surface bonding of the glass cloth and resin to the faces of your strips is going to keep those strips in place anyhow. There is a lot of surface area for that resin to bind to!

I'd think the biggest problem with working in a cold shop would be the effect of the cold on the carpenter. Add a few lightbulbs or a small heater to kick up the temperature of your work area a bit so you'll be more comfortable.
