There is a clear teflon tape sold by Catalina dealers which works great to smooth the sliding action of the companionway hatch on my SunCat. It is not so slippery as to cause problems with a sloppy hatch. The tape has lasted two seasons without apparent wear. It was costly, as it was sold by the foot. As I recall, it was about $10 or $15 for the two 3-foot lengths I needed. Russ Browne P J Puddlejumper ComPac SunCat #16 Branched Oak Yacht Club Sailing the prairies of Nebraska
