[Public-List] block sized

[Roger L. Kingsland]

With my old wood spreaders, it appears the tapered edge slopes aft while the
vertical edge runs athwart ships; so, putting the tapered edge forward,
results in the stays about even w/ the back of the mast.  Hope it's FAST.

Has anyone priced new aluminum (is carbon fiber class legal?)spreaders?
Sure would be nice to get that extra few pounds off the mast.

Best, Roger 148

I think the tapered edge is supposed to go forward, however, the
spreaders by design were never supposed to sweep aft.
I did that on my Boat, Infinity 7+ years ago and found she performed
much better in big air, but no marked improvement in light air.
It was pointed out to me that the spreaders were on backward, but we
were winning so who cared. We got a bigger belly in the main as a result
and did tighten up the slot some. But it does work against the natural
run of the shrouds.
