I presently have a 2001 3780 with twin 420 gas volvo and the boat fits us well. I came across a 2006 3880 leftover with options that I would prefer 440 Yan, bow thruster, better electronics,and new canvas. My 3780 canvas is at its end and needs to be replaced.I was woundering what anybodys thought are on having a new boat servey. Would this be a waste of money or over kill. Would also appreciate any other insight on this matter.
