Another aim of my invention'yis- toxprovide

Still another object of theinven-tion is to pro

greater than. half the circumference vof the gasket,
and, the opening 10f. thesgrooveis, less. in width
than the. diameter ofpthe. gasket. This oft-center
arrangement. has the advantage. that the. corre
sponding part of the gasket may be ?t».in...the
larger-groove where it will remain without atten
tion, and then the adjoining section of the de
vice, transverse or longitudinal, may be more
easily placed in relation thereto.
When the oif-center grooves are used all of the
keel sections on the same side of the canoe pref
erably have the larger groove.
Further, the larger grooves in the rib sections
should be placed in accordance with the order in
which it is desired to assemble the canoe. For
example, if it is desired to assemble the canoe
from stem to stern, if the larger groove is placed
in keel 49 of stem section 20 and in the rib 43
at the rear end of section 20, the gasket may be
?tted into the larger grooves in section 20 and
then the sections I8 and 24 may be easily ?tted
with relation to section 20 with much greater ease
than if the larger groove were in the forward end
rib of section 24. Also, if it is desired to assemble
stored in a more compactmanner.

that of the rib of a conventional canoe. The an
