Title: Location of hound pivot bolt interpretation
Post by: Bob Rast DN1313 on February 19, 2013, 07:45:56 AM
Ive been trying to determine correct measurement for mast hound pivot bolt hole ?
Specification says base of mast.
Is Mast socket considered  part of base if so where is specification for this?
If you use the mast base without socket and spec says with socket you are 1 inch higher than minimum.
If you use socket ,adds  about a inch and spec is to base without socket you are below MInimum
Ive looked through the general fittings and rigging and cant seem to find spec that includes socket for this measurement


13.Distance from lower mast hound bolt (pivot bolt located in front of mast) to base of
mast:
139-1/2 max  127-1/2 min 3543 3239


Thanks

The issue here is the use  of the terms "bottom of the mast" or "base of the mast" and what is included in the "bottom" or "base". 

Specification C.1.a. clearly establishes that all hardware (at top and bottom, or base) are part of the mast.  Measurements include all parts of the hardware.
 
Specification C.3.e. requires the bottom of the mast to be fitted with a socket.   This tells us the socket is included in the bottom of the mast.    Therefore it is included in the "base of the mast".   Any measurements taken from the base of the mast must include the ENTIRE socket, no matter what the design of the socket hardware.  Measurements are  NOT taken from the bearing point of the socket. 

Innovative sailors have tried several designs for the socket and over-time the now popular screw-in socket has been found to work effectively and complies with the specifications.
