I am being penalized through our club measurer for having an elongated boom (six seconds). Does anyone know the proper length of a stock Mark 1, 1971 boom?

"E" measurement is 10.5 feet -- it's longer than a Mk 2 or Mk 3/4 boom.

Isn't the "E" measurement the length of the foot, not the boom? On my Mark I, the boom is over a foot longer than the foot of the sail. This is because the mainsheet leads from the end of the boom to the traveller which is mounted at the aft end of the cockpit.

Thinking twice, our measurer (Hugh) measured the sail, not the boom.
Anyhow I believe the measurement should be from the aft face of the mast to the black band near the end of the boom.
The PHRF-LO website should have this information -- the "how-to measure".
EDIT: The PHRF definition of "E" is from the aft face of the mast to the maximum point the main is permitted to extend. This means normally the black band -- and the foot of the mainsail needs to be measured to confirm that "E" is equal to or less than 10.5 feet for a Mk I.
