All six share the final /oʊt/ sound with the -boat ending of speedboat (spelled -oat or -ote). Because speedboat's stressed syllable is /spid/, these are not full rhymes of the whole word; 'seed' /sid/ and 'need' /nid/ rhyme with that stressed syllable instead. Beware the lookalike 'boot' /buːt/, which does not sound like 'boat'.
