Just wanted to make note of a boat experiment that went well. I bought some "slippery tape" from Lee Valley Tools and put it on the bottoms and drawer slides on the boat along with the companionway slide. It did a really good job of reducing friction and making everything slide more easily. I did 11 drawers and the companionway with one roll (a lot of cutting the wide tape in half and it fit the drawers perfectly). You can read about it at http://www.leevalley.com/wood/page.a...at=1,110,43466
Lee Valley have a lot of very interesting, high-quality products, especially if you are into woodworking or gardening (and no, I do not have a connection with them other than that they have collected a lot of my money over the years). They have stores in Canada and sell online through locations in Canada and the US.
