[Rhodes22-list] Critical Standard Mainsail StandingRigDimensionsFor Rhodes 22

[Rob Lowe]

Lloyd/Sarjo/Roger,
More interesting information.  My 76 (RC 249 I believe is what my main has
on it) has neither a rotating boom, nor reefing points, in addition to
lacking holes above the mainsail gate on the mast.  It does have a downhaul
line on it, but nothing to cleat it off to.

Rob
