These words share the spelling -aft and rhyme with kraft /krɑːft/ in British pronunciation (/ɑːft/: craft, raft, draft, graft, shaft, daft). In American English these are usually /æft/ (e.g., craft /kræft/), so they do not rhyme with an /ɑː/ pronunciation of kraft. 'Waft' also looks similar but is usually /wɒft/ in British English, so it is not a rhyming match.
