Thanks for sending me this the other day Bot! I love PT boats and had the pleasure of seeing one in action recently, although sadly I didn't get a ride.
She is a Vosper, last one left! A bit smaller than an Elco or Higgins. Sadly she has a pair of Detroit 8v92TIB's, which are only able to push her to about 20 knots. But never the less seeing that boat moving along was very cool! To bad it didn't have the triple Packards 5M-2500's so she could scream along at 50 knots! While burning 500 gallons per hour!
