A quick tip for those who might want to take the leading edge
spars out of the BoT; the spar connectors are bonded pretty
solid to the spars, but there's no need to force them off
because they part real easy if you apply steam to them (from
a kettle say).  You can remove them without any damage at all
to the connector, and can reglue them later.

Only thing to watch for - don't burn the sail on the kettle
spout!!!
