"FALL-OFF" SLIGHTLY TO LEEWARD. THIS SHOULD GIVE THE MAST A
SMOOTH, EVEN CURVE FROM HEAD TO DECK. SIGHTING ALONG THE BACK
OF THE MAST ON EACH TACK, FROM DECK LEVEL, WILL GIVE A COM
PARISON AND INDICATE THE NECESSARY ADJUSTMENT.
5) WHEN RACING, THE BACKSTAY MAY BE TIGHTENED UP TO COMPENSATE
FOR THE ADDITIONAL FORWARD LOADING APPLIED BY THE GENOA. AT THE
CONCLUSION OF THE RACE IT IS BEST TO "SLACK-OFF" THE AMOUNT YOU
"TOOK-UP" ON THE BACKSTAY TURNBUKLE. THIS AVOIDS UNNECESSARY
STRAINS ON THE HULL AND RIG. UNDER NO CIRCUMSTANCES SHOULD ANY
OF THE RIGGING BE SET UP "BAR-TIGHT".
6) TOO MUCH TENSION ON THE BACKSTAY IS PROBABLY THE PRIME REASON
FOR MAST AND RIGGING FAILURE. BE EXTREMELY CAREFUL WITH HYDRAU
LIC TYPE ADJUSTERS.
