: is way too expensive)

Are we talking a basement or a garage or a barn?

You really want to get some heat into your work area for a variety of reasons. Consider your least expensive options. 1500 watts of electric heat is about 15 cents an hour. For the price of a can of soda you can heat your workspace for 4 hours. 1500 watt electric space heaters sell for $15 to $75. They all give off the same amount of heat--1500 watts of it! Some have fans which circulate the heat better. Buy the cheapest you can find.

Theoretically you could just plug in ANY electric appliance that uses 1500 watts and you will heat the area with it. But many appliancew will wear out if run continuously. A simple and durable option is to use lightbulbs. Three 500 watt halogen lamps strung up over the work area, or on stands surrounding ht area, will heat the worksurface by radiant heat, and heat the surrounding air by convection. The majority of a barn amy be cold, but the area around the boat will be much warmer. The light also warms the carpenter!

There are radiant Infra-red heaters which attach to the top of propane tanks. Again, these can be aimed at your work area to keep that warm enough to work in.

If you have to leave your work at night, you can drape a tarp over the hull and put 2 or 3 100 watt light bulbs on the floor underneath this. The heat rising from them will be trapped by the tarp and your glued areas will stay above freeszing long enough to set properly. You can use some cheap table lamps. See what you can find at a garage sale. Keep the lampshades on them and these will keep yourtarp from brushing up against the hot bulb should it be moved by some draft or stray air current. Or, get a couple of the clamp-on workshop fixtures with the reflectors.

Other possibilities are wood burning stoves, natural gass heaters, torpedo heaters, and kerosene heaters. Your workspace conditions will setermine whether any of these can be made to work for you. They are not that expensive to buy--particularly when you consider that they give you an extended building season. When you are done with your project you can sell it at a garage sale and recover some of the cost.

If the temperature gets very cold you may want to work on some other project this winter and wait until spring to work on the boat. Set up the strongback and forms and then cover it up durig the coldest months.

Hope this helps.
