International Thunderbird Class Association
Preface
This edition of the Black Book incorporates all revisions to the
Constitution and Specifications through January, 1994. The
Specifications section was reorganized to place all information on
one item (e.g. "mast") at one location. Ml changes from the 1987
issue are identified with a "bar" in the fight margin. In general
revisions can be made only once per year. The basic definition of
the Thunderbird Class boat is fixed and further changes to this
Black Book will not invalidate the measurement certificate of
existing Boats. Revisions that are officially accepted since printing
of this addition will be published in International (I.T.C.A.)
newsletters. Update information is available by writing to:
I.T.C.A
P.O. Box 1033
Mercer Island, Washington 98040-1033
U.S.A.
Although not an official part of the Black Book, Tips to Builders
has been added to this document rather than providing it
separately. This is a matter of convenience. Additional tips are
actively solicited.
Acknowledgment and thanks is given to Jack Foster for providing
the initial Specification draft and to Sandy Pratt, Bill Hurley and
Roy Dunbar for coordinating updated Specification drafts for class
acceptance. Thanks to Garth Wilcox for doing the Specification
drawings.
April, 1994
