Summary

Testing
showed
no
degradation
in
capacity
due
to
moisture
or
liquid
gasoline
exposure

Regenerable
carbon
capacity
was
maintained
throughout
test
period

Carbon
capacity
was
unaffected
by
physical
stresses
associated
with
marine
use

Carbon
canisters
did
not
affect
performance
of
boats

Future
Work

Carbon
canisters
will
be
removed
from
boats
and
tested
for
particle
size
distribution,
heel
analysis,

and
capacity

Two
canisters
will
remain
on
boats
for
long­
term
testing
