Part of the Mabel Muttley Series.
Mabel, the 109 year old primary school pupil, can't swim but she is excited to be entering the novelty race in the school's swimming gala. She has built herself a very special boat made out of an old tin bath. But Sidney Scrimshanks is entering the race too and he thinks nothing of cheating to get the gold. It is up to Mabel to make sure that he doesn't succeed in his nasty tricks.
