Another "on the boat" vet to come forward?

According to a Freeper watching CNN Crossfire, Kerry could have more problems:

(Bob) Novak implied that one of the two men on the boat with Kerry during his first Purple Heart will come forward to contradict Kerry’s story. He wouldn’t tell (James) Carville the name of the person, but said it would come out soon.

UPDATE: BeldarBlog has more details:

I'm told that now coming across the newswires is a new column from Bob Novak that contains extensive quotes from Retired Rear Adm. William L. Schachte Jr. Schachte, call-sign "Batman," has broken his press silence to insist that he was indeed aboard the Boston Whaler or "skimmer" in the early morning mission on December 2, 1968, out of which Sen. John Kerry's first Purple Heart was awarded. Schachte maintains that Kerry's minor arm wound was not sustained while under enemy fire, but was indeed the result of Kerry — code-named "Robin" on this mission — being careless in firing an M-79 grenade launcher. Other officers are quoted to support the likelihood of Schachte's presence.
