30 footers were PBRs - patrol boats, riverine. Essentially Jacuzzis on water. Would love to get my hands on one today, but they were all left behind in RVN. Also - Martin Sheen did not drive the PBR into Cambodia - the "Chief" did. Sheen was a USA captain, not a navy ossifer.
Kerry's own reference to that movie -- which I hadn't known about prior to today through the more complete Instapundit quotation -- seems very telling to me. It is also consistent with the combat cap story from the Washington Post two years ago, that Kerry carries in his briefcase today a "cap given to me by a CIA agent on a secret mission."
How do you add those details up from your own standpoint?
