[PUP] BSFC (wasKrogen 55 Expedition vs Dashew FPB64)

[Robert Miller]

Not to take away from your conversation about the Krogen and Dashew, but
this is my first post to PUP.  I would like to know from you what you
consider the top five passage makers to be and why.  My wife and I are
getting very close to retiring to a boat and intend on extensive cruising.
I have been reading Passage Maker for some years now and would really like
some "real world" help on the purchase of a passage maker.  Considering
safety and fuel consumption, I could really use some help.


Kindest Regards,

Robert Miller
