The cedar boats with jet motors are quite common on the Restigouche. I think they need something like 3" of water to run in, which makes them quite popular with people who don't know how to really run a boat, especially in low water. I've seen some of them with steering wheels instead of the motor handle. They are boat with a really, really wide stern on them.
If you're in the area, i.e. Campbellton, there are two booklets of free classifieds that come out every month. The booklet costs about $2 to buy, and there is usually quite a few listed in there. One is "Un peut de tout"(french) and the other one is "Buy, Sell and Trade" or "The Restigouche Shopper's Guide."
I think they are more pricey to buy and maintain though than regular cedar "motor boats", especially the motors. I've heard of the jets blowing up because they got sand in the intake and it blew the motor. My neighbor makes the old style ones with the regular motor. He also makes regular paddle canoes(16' I think) and also makes the most beautiful coffeetable boats, which are appoximately 4 feet long. I lust after one every time I got to his shop, but it will have to wait a few more years before I can buy one.
