OFFSET REVISIONS
1.
General Notes:
The offsets in
CanoeCraft are for the station molds. There is no need to reduce the
offsets for the thickness of the planking - that has already been
done. Unfortunately, this is stated incorrectly in the text on page
42, second column, fourth paragraph of the 2000
edition.
2. Stem
and Mold Offset Revisions
The revised and
expanded edition of CanoeCraft contains offsets for 8 fine
canoes. The stem offsets for the Rob Roy, the Bob's
Special
and the Ranger contain some typographical errors. There are
also corrections in the half-breadths for the Freedom 17 and
the profile for the Hiawatha 15. Many thanks to our sharp-eyed
builders for pointing these out. We present here the correct offsets
for these boats. If you wish to make your life even easier you may
purchase the full size drawings
(including all stations and both stems, full size).
The stem offsets
are horizontal measurements from the station listed in the table to
the outside edge of the inside stem. Therefore the stem mold that you
make should be cut back to allow for the thickness of the inside stem
(normally 3/4" on the canoes). Units are feet-inches and
eighths, +=sixteenth. See sketchbelow.
