Drew answered why.

I'll add that you could use looking-at:

(defun goto-vowel ()
 "Skip to next vowel after point."
 (interactive)
 (while (not (looking-at "[aeiouy]") (forward-char)))

More over, only in iso-8859-1 there are a lot of other vowels:
 
    ÀÁÂÃÄÅÆÈÉÊËÌÍÎÏÒÓÔÕÖØÙÚÛÜÝàáâãäåæèéêëìíîïòóôõöøùúûüýÿ

(and what about semi-vowels like y? In some languages it's considered
a plain vowel).




One would hope to be able to use the character categories and match \C1 as in:

    (while (looking-at "\\C1") (forward-char))

unfortunately, in the default category table, the consonant/vowel
attribute is not set for ASCII characters.  You'd have to build a
correct category table.
