A Manatee is slow and Graceful, also similar in shape.  Manatee's also have a great nature.

 "A
 knot or less" and "Manatee" both suggest
 sluggishness to me, but I think this little boat will move.
 My wife is suggesting "Shackleton" since I really
 like the fellow and he was a relative. So that one's in
 the lead, but I'm still pondering it. If she were a
 one-person, I would name her "Batchelors Delight"
 after a pirate ship that I think had the best name of all
 time.  Yesterday I did something I hadn't done in a
 long time, and actually looked at a list of baby names. This
 is fun.

 Hi   
   Alec,

 How about "The Equalizer" or "A knot or
 less".
