blocks on deck near the mast..."
Here's a couple of ideas..
1) If you are building the blocks yourself, you may
be able to design them with the exact angles you
need to direct the lines from cockpit to mast.
The only reason you need springs is to allow the
block to assume the correct angle under strain,
yet keep it from banging on the deck when the
tension goes out of the line. I would look at
building a turning block flat on the bottom, angled
correctly, and bolted flat thru the deck.
2) I have seen wooden blocks fastened to thru-bolts
in the deck. The bolt is surrounded by a flat mat
woven from heavy rope. The mat cushions the block
and prevents it from banging on the deck when
tension goes out of the line. There is an illustration
of this, as well as instructions for making wooden
blocks, in Hervey Garrett Smith's book "The
Marlinspike Sailor" ISBN 8286-0044-9.
Good luck . . . Kurt
