Assuming the cloth is cotton and isn't coated to reduce water 
absorption.  I don't remember my hockey sticks getting heavier with 
water in the old days - the tape was kinda tarry.  The hockey tape I 
have now is not cloth.

Cotton is the fabric of choice in this case, since its hydrophilic 
(unlike most synthetics) and swells noticeably when wet.  In the old 
days before sealed seams, they would use cotton thread in jacket 
seams. The thread would swell when wet and fill the needle hole to 
minimize water leakage.

Speaking of tape - I saw that 3M now sells a Scotch Duct Tape: clear, 
not grey and advertised as stronger than the old stuff.  Now you can 
do the Red Green thing without the Red Green look! :-)  Available in 
small rolls just right for your kayak repair kit.  (no affiliation 
etc...)
