Catalina vs. JSI Sailnet
It might not be completely clear from the earlier posts, but the JSI Sailnet spreaders are made to fit your existing brackets. Ironically, the Catalina version is of a different configuration requiring that you remove the mast to replace the old brackets, which is not a trivial job. I haven't done it yet, but when I do, I'll opt for the JSI approach. The only disadvantage I can see is that you're out of commission while they have your old spreaders. It wouldn't be too difficult to fashion some temporary replacements using your old ones as a pattern. Straight grain Douglas Fir would be a good, relatively inexpensive (but somewhat heavier) substitute for the originals which I think are made of spruce.Personally, although I will eventually convert to aluminum, I think the wooden spreaders have received somewhat of a bum rap. Boats had wooden spreaders for years before aluminum took over and they weren't prone to failure. I repainted the wooden spreaders on my '81 C-30 a couple of years ago and could find no signs of rot, cracking or deterioration despite the fact that the tops were almost completely bare.For those of you who do continue with wooden spreaders, think about using a high grade exterior house paint. The spreaders are so high up there's no point in using an expensive marine paint and the house paint is formulated to stand up quite well to the elements. If you absolutely have to use varnish, paint the tops and varnish only the bottom and edges.
