Building a small Catamaran using pine and spruce.
No, I am not crazy.
The year is ending in cottage country and I just finished building a 8 by 8 walk-in closet, this let me finally clean up my cabin, use up the lumber and plywood I had lying around the place and generally get organized. At this point I found myself looking at my 16 foot 6 inch Prospector fiberglass/kevlar canoe. Because I never got around to building a rack for it, it had been left on the ground a lot and basicly most of the wooden was rotten to one degree or another. After removing all the old wood I found the glass hull to be in fine condition, just needing new wood work. At this point I decided my dream of building a catamaran should become real. However, a quick trip to the local hardware store told me my dreams of building a cedar design will cost me big. Since I have been all thumbs in my previous boating attempts this could be a big waste of money. However I had some very clear (no knots) spruce 2*4*8 pieces and a large number of cottage grade (cut very thin) tongue and groove pine pieces also 8 feet long. I quickly realized that I could make all the needed wooden parts out of these materials but short of encasing in epoxy what is the best way to extend the life of these woods if they come in say monthly contact with water? Epoxy will work but I assume I must glass the pieces as well, and that will add a lot of weight. Varnish, is easy - but does it trap water inside if there is a break and rot the wood inside out? Linseed oil should work, would I have to oil it every time I take it out on the water? I have some Teak Oil from a friend, is it better than Linseed? No treatment? Leave the wood bare but make a special rack so no wood touchs the ground and a simple open roof so the wood dries naturally but and rain is kept away? Any thing I missed?

A boat that gets wet? Where do you get these radical ideas?

Earl Colby Pottinger Several people have suggested it: for a budget boat (and you must know that clear spruce can have great strength/weight but it is not durable nor water -resistant.) you could use premium water-base 25 year external house paint. More water restance for the buck than any other coat, probably. Or oil-base house paint. But tougher to clean up - with costly (?) solvent. Brian Whatcott Altus OK |

Brian Whatcott :

For some strange reason until you mentioned the paint I forgot that I used a outdoor deck paint on my floating dock. All the parts that you walk on show wear and sun damage but last year when I was working on the barrells I noticed that the lower wood looked it new. I think your idea will work out fine.
