the epoxy is probably less smelly than latex paint. if you can paint a wall without bothering the family, you can do a boat.

But, keeping a window open a crack will help the ventilation a lot.

Close off the room where you are working -- as best you can. I've just read of one person using plastic sheeting. That sounds like a good idea if you can't just close a door to the room.

Since it is cold outside, consider opening the window a crack jsut as soon as you put the last drops of resin on the boat. This will not only suck the heated, resin-smelling air out of your house, but it will cause the room temperature to drop a bit, which should be considered a benefit, as it should reduce outgassing from the wood.

If you are working with the windows closed, though, then you definately need a respirator mask, as you'll be breathing nothing but those fumes for a few hours -- and you don't want to do that.

Once you start glassing plan to procede at a rapid pace so you finish the entire job before anyone gets fed up with you. Once the resin has started to harden and the boat can be taken off the forms and moved, get it out of the house. It will smell of plastic (that "new car" umm boat smell) for a while If you can move the whole thing while it is still on the forms, that is even better. By the time you get around to varnishing it the weather should be better.
