T&T: 18 knot displacment hull with a 45ft waterline length

[John Holbrook]

Interest design appears to use two rudders space far apart at the stern. I would guess that at higher speeds the rudders are turned a few degrees out, port rudder to stb and stb rudder to port to give the stern some lift. 
   
  Also interesting to see the lightship weight at 32,000lbs. Makes me wonder why typical 50ft trawlers are nearly twice that.
